Ask a business owner how they manage to keep track of every mobile phone of the company. Sweat beads will form on the forehead just by thinking about losing the phone or getting the data hacked. Gone are the days when food, clothes, and a roof were the basic necessities of life.

The bare necessities of life in 2023 and post-2023 are – Food, Clothes, a Roof, Mobile phones, and the Internet…

And to add one more to the list – mobile device management software.  

What is Mobile Device Management Software?

Mobile Device Management is any software that allows companies to keep track of their devices in case it is lost, broken, damaged, or stolen. It can automate and control the administrative policies on all the devices connected to the organization. It is one of the top technology trends that will save the company and the employees.  

Basically, in a time of crisis, it allows the organization to erase or lock all the critical confidential data which could otherwise ruin the company. Mostly, the employees who are deployed with organizational devices have this immense pressure to be careful with it. Still, a person could be so cautious, let alone stress themselves, to the point of returning the device.

And god forbid, if it is stolen, how deftly they will be punished. Hence, this is where Mobile Device Management Software will come to the rescue. Think of it as an antivirus saving the device from damage, and imagine not worrying about taking the data backup because it is all there on the cloud.

Keeping control in the employer’s hand, the employee is provided with a device with pre–installed apps and software that will be used by the employee to perform their task. With MDM software, the company can track, monitor, troubleshoot, and even wipe device data in the event of theft, loss, or a detected breach.

Features of an Mobile Device Management Software:

A Mobile Device Management Software should have the following features to make it the best of the best. Otherwise, it is simply a waste of money and resources.

• Security

Security feature ensures that your mobile data is being protected. If this feature is working out properly, then it will be able to detect the compromised device and take care of the situation.

It will also be able to detect malware, allows, and dentist applications too. It will monitor outbound commission, block all the commission, alerts the users, and prevents the data from getting into the wrong hands.  

• Data Wiping

There is no use if the MDM software does not have a data-wiping feature. Losing the device is one thing, but failing your competitors who can hack it and use it to their advantage is next level. And you don’t want things to turn ugly.

Thus, if there are chances that the stolen device will not be retracted at any cost, the data wiping feature comes in handy. The company should be able to wipe the data remotely from wherever the device is.  

• Location Detection Turned On

Location Detection is not just about locating the lost or stolen device. It will also provide custom options to lock a few apps as soon as the employee steps out of the company premises. Their location will be known, and their activities can be tracked and monitored. And demographic terms and conditions like the device shall not be taken away from certain miles from the office, and if done so, it will auto-lock itself. 

• Responsive Integration

The Mobile Device Management Software that your company chooses should be one that can run on all kinds of devices. The mobile device management software shouldn’t be limited to mobile phones, even though the name suggests.

Because there might be people who own devices other than mobile phones for them, responsive integration of software is necessary. 

• BYOD Integration

Not everyone will be getting the company phone because not every company is big enough to have a lot of phones for all the employees, but that shouldn’t limit software. It is something that can be installed in every phone with the option to uninstall or lock it once they are out of the premises. 

Plus, it will save the company’s cost of allotting every employee a phone, tablet, or Macbook and even still functioning however it is required to. 

Reasons your company needs Mobile Device Management software

Generally, there are no significant reasons for the company to get Mobile Device Management Software unless they want to protect the devices allotted to their employees and protect the confidential data from getting stolen, but here are a few other reasons:

1. Data security is the top reason, and the second one is low cost. With BYOD integration, the company doesn’t need to provide a separate device for all the employees. It can be integrated into the employee’s device itself and be beneficial.
   
2. The company can control the application usage, promoting work–life balance. Also, it will prevent the employee from misusing the company’s resources.
   
3. Depending on the size of the company, a single device could be used by multiple employees, which is why it is necessary to keep track of inventory as well, and that is when MDM software comes to the rescue.
   
4. When MDM software is centrally managed, it reduces the cost of employing admin departments that need to keep track of devices, data, staff, etc. One can install, uninstall, and update the software from one management dashboard.
   
5. Every industry has specific rules about protecting the data, and getting the data leaked can not only be dangerous to the company but individuals who are their customers and clients. Thus, password-protected software must be installed to adhere to such rules and regulations. 

Key Takeaway From This Article:

If you have read till here, you must know what’s coming next. Yes, your company/business needs MDM software. It is a fantastic addition to the industry that runs primarily on mobile devices. Everyone in the company, who owns a gadget, should have mobile device management software installed in it.

1. Understanding React Router

React Router is a widely used library that provides routing capabilities to React applications. It allows users to define routes and navigate between them without needing page reloads. React Router abstracts the complexities of handling URLs and provides a declarative way to define the flow of your application.

When working with React Router, it’s essential to understand its core concepts. One of the key concepts is the Route component, which maps a specific URL path to a corresponding component. By defining routes in your application, you can create a hierarchical structure and determine which components should render based on the URL.

In addition to routes, React Router also offers various navigation components, such as Link and NavLink, which provide a seamless way to navigate between different pages. These components automatically update the URL and trigger the rendering of the corresponding component, resulting in a smooth and interactive user experience.

2. Setting Up React Router

To get started with React Router, let’s install the necessary packages. Open your terminal and run the following command:

Once the installation is complete, we can proceed with the basic configuration. In your main application file, typically “index.js”, import the necessary components as follows:

3. Navigating with Link and NavLink in React Router

React Router provides two components, ‘Link’ and ‘NavLink’, to create navigation links within your application. Let’s take a look at how they work:

The ‘Link’ component allows us to create links that navigate to specific routes. The ‘to’ prop specifies the target URL. Similarly, the ‘NavLink’ component works the same way but provides additional styling options. The ‘activeClassName’ prop allows us to apply a specific class to the active link, enabling us to style it differently.

4. Route Parameters and Dynamic URLs

In many cases, we need to handle dynamic segments in our URLs, such as user profiles or product pages. React Router allows us to define dynamic routes using route parameters. Let’s see how it works:

In the example above, the ‘:id’ part in the path is a parameter that can be accessed within the ‘UserDetail’ component. We can extract the parameter using the ‘useParams’ hook:

5. Nested Routing and Layouts

React Router supports nested routing, allowing us to create complex page hierarchies. We can define child routes within parent routes to handle sub-components. Let’s take a look at an example:

In the example above, the ‘Dashboard’ component acts as the parent route, and the ‘Profile’ and ‘Settings’ components are nested within it. This enables us to render different components based on the URL.

6. Programmatic Navigation

React Router provides the ‘usehistory’ hook and the ‘history’ object to navigate programmatically within your application. Here’s an example:

7. Route Guards and Authentication

In real-world applications, it’s crucial to implement route guards to control access to certain pages based on authentication or user roles. React Router provides a mechanism to protect routes using the ‘Route’ component and custom logic. Let’s explore how to implement a basic route guard.

The ‘PrivateRoute’ component acts as a wrapper around the standard ‘Route’ component. It checks if the user is authenticated and renders either the specified component or redirects them to the login page.

Now, you can protect your routes by using the ‘PrivateRoute’ component instead of the regular ‘Route’ component:

This ensures that only authenticated users can access the dashboard route, while others are redirected to the login page.

Conclusion:

Congratulations on mastering the art of leveraging React Router to create seamless navigation within your single-page applications!

1. Writing many components in a single file

This is one of the most common mistakes that many developer make. Developers tend to write most of the React code in a single file even though they splits the components, still writing all the code in a single file is not the best practice.

In the above example, the code will be executed completely fine though the reasons why it is not considered as the best practice are:

1. The size of the component will increase by may be 15, 20 or even 30+ lines making the component difficult to understand.
2. The UserField component is not Encapsulated, being used in the same file as in App.js does not hide the component UserField from the outer world. To hide the component details we have to export the UserField component from a different file and then import the component in App.js file.
3. Unit testing for UserField is not possible, as the component is not isolated and is in the same file with App component.

2. Not using setState callback to update state correctly

Many times setState is used twice in the same function to update the state value, many developers forget to use the callback provided by the setState, which might not update the state with the correct value.

In the above code for Counter, after clicking on the button the count value will be increased only once though it should be incremented by 2. After clicking the button the count value will be 1 . This is because in case of the second setCount (line 8) the count value is still 0 and is not updated because in React, the state value is always after the execution of the function. That’s why even for the count in second setCount is 0.

Using the callback provided by setState method can fix this issue. This is because now in case of the second setState, it will consider the current/updated value of count and then will increment the count value by 1. After fixing the code, when the button is clicked, the count is updated correctly. The count is now incremented by 2.

3. Invoking components with wrong syntax

Many times the components are invoked directly using JS functions which created many issues.

The above code looks fine and when executed, the working of the code will look fine though its having the following issues:

1. By directly invoking the component, we are basically creating a custom hook of UserField and the code is re-rendered multiple times when the value is updated in the input field.
2. With the above code, not only the UserField component is re-rendered but also the App component is re-rendered when the state is updated in UserField component. This is because invoking the component directly, the component is now being treated as a custom hook and every time the state value in the component is updated, the HTML is returned causing re-rendering of App component as well.

To fix this, instead of directly invoking the component we have to call the component as an element <UserField /> .

Conclusion

In conclusion, React is a powerful and flexible library for building complex user interfaces. However, it’s easy to make mistakes when working with React. Some of the most common mistakes include not using state properly, invoking components with wrong syntax, not understanding the component lifecycle, and not optimizing performance.

Remember, React is just one part of a larger ecosystem of web development technologies. It’s important to understand how React fits into the bigger picture, and to be comfortable using other tools and frameworks as needed. By keeping these tips in mind, you can avoid common React mistakes and build better, more effective applications.

The post Big mistakes we make in React appeared first on Deqode Blog.

As an alternative to the well-known NodeJS, Deno is a contemporary Javascript runtime environment. Deno was developed by the same person who developed NodeJS, Ryan Dahl. The goal of the project is to solve some of Node’s shortcomings that have emerged in the thirteen years after its release.

Deno is more in line with current coding requirements. Decentralized package management is available, TypeScript and WebAssembly support are built-in, and security is given priority. Unless you specifically allow it, Deno runs code in a sandbox without access to the file system or the network.

NodeJS is fantastic and will remain the de facto standard in the JavaScript community. However, because of Deno’s superior TypeScript support and cutting-edge standard library, it will eventually gain popularity.

Some of DenoJS’s distinctive qualities that set it apart from NodeJS are as follows:

• Deno is based on modern features of the JavaScript language
• The feature has an extensive standard library
• It has TypeScript at its core, which brings a huge advantage in many different ways, including first-class TypeScript support (you don’t have to separately compile TypeScript, it’s automatically done by Deno)
• Deno embraces ES modules
• No package manager
• First-class await
• It has a built-in testing facility
• Deno aims to be browser-compatible as much as it can, for example by providing a built-in fetch and the global window object

A little bit on NodeJS

NodeJS was created to handle asynchronous requests to the web server. For instance, NodeJS handles opening files by sending them to the file system and quickly returning them to work.

After the file system responds to earlier queries, servers merely send responses (in this case, the file’s contents) to clients. As a result, NodeJS uses less memory and handles requests more quickly.

NodeJS is also capable of gathering form data, producing dynamic pages, and carrying out all server-side file actions including opening, closing, reading, writing, and deleting as well as adding, removing, or updating database data.

A better version of NodeJS, Deno, was created to take care of NodeJS’ deficiencies. It enhances the security of JavaScript runtime environments.

Check out our NodeJS-specific solutions here.

Deno vs NodeJS: Similarities and differences

The most used JavaScript runtime outside of web browsers is NodeJS. Because of its widespread use, you can access a top-notch community of knowledgeable developers. Built on npm, the NodeJS package ecosystem is extensive and simple to maintain. This implies that Node is frequently the best option if compatibility and familiarity are your main considerations.

However, Node hasn’t gotten everything right. Deno makes advancements in a number of crucial areas, especially those related to security and standards compliance. Because Deno is a single binary, it is more portable than Node, and the open-ended module architecture may become the standard for dependent imports in the future.

The only similarities between them are that they both are developed upon the V8 Chromium Engine and Both are great for developing server-side with Javascript.

On the other hand, DenoJS stands apart from the NodeJS in following ways:

Typescript support:

The TypeScript language extends JavaScript by enabling customers to provide type data. By using a TypeScript compiler with caching techniques, Deno comes with TypeScript out of the box.

Permissions: 

In addition to supporting JavaScript and TypeScript, Deno is known for its secure runtimes. The permissions system plays a part in maintaining security. Deno allows the following permissions list:

• –allow-env=<allow-env> – allows all environment access like getting and setting of environment variables.
• –allow-hrtime – measures time with high resolution.
• –allow-net=<allow-net> – allows network access.
• –allow-ffi – allows you to load dynamic libraries, it does not have the same security reasons as others since it does not run in sandbox. Use with caution because it is an unstable feature.
• –allow-read=<allow-read> – Read access to the file system is allowed. To provide an allow-list of files and directories you can specify a comma-separated list.
• –allow-run=<allow-run> – Running subprocesses is allowed. The Deno 1.9 release adds the ability to specify an optional, comma-separated list of subprocesses to be allowed. In contrast to the Deno process, subprocesses are not run in a sandbox and therefore have fewer security restrictions.
• –allow-write=<allow-write> – Write access to the file system is allowed. To provide an allow-list of permitted file system access, you can specify a comma-separated list of directories or files
• -A, –allow-all – Allow all permissions. This enables all security-sensitive functions. Use with caution.

Browser Compatibility: 

Browser compatibility makes it easy for developers to build applications that can be run in both the browser and Deno.

As much as possible, Deno will use web platform APIs (such as fetch) instead of introducing proprietary APIs wherever possible. 

Deno implements the following web platform APIs:

Fetch API: The fetch API provides an interface that allows you to make HTTP requests to servers from web browsers. It requires only one parameter, the URL of the resource that you want to fetch.

Web Worker API: In web applications, Web Workers enable script execution in a background thread separate from the main execution thread.

Standard Library:

Among Deno’s features is a large standard library of modules evaluated by the core development team. There are no external dependencies on any of the modules in the standard library.

The Deno standard library provides a set of modules that are used for a variety of tasks, including:

• Making HTTP requests for Deno
• Working with the file system
• Prints formatted output with helpers
• Test and benchmarking your code using basic utilities.
• Helpers are included for handling XML, CSV, base64, YAML, and binary files

Installing Deno:

Deno is delivered as a single executable that bundles all of its own dependencies. Direct downloads or the majority of well-liked package managers are options for Windows, macOS, and Linux users.

-The installation script is the simplest route to get Deno running on Mac and Linux systems:

$ curl -fsSL https://deno.land/install.sh | sh

This will install Deno to the .deno folder inside your home directory. Add this location to your PATH so you can use the deno command without specifying the full path to your binary. Edit your ~/.bashrc (or equivalent for your shell) and add the following lines at the bottom:

export DENO_INSTALL="$HOME/.deno"

export PATH="$PATH:$DENO_INSTALL/bin"

-Open a new shell window and try the deno command:

$ deno
Deno 1.24.2
exit using ctrl+d or close()
>

-You’ll be dropped into an interactive REPL where you can run JavaScript code:

> console.log("Hello World");
Hello World
undefined

-Exit the REPL by pressing Ctrl+D or calling close():

> close()

You can run an existing JavaScript file with the deno run command:

$ echo "console.log('Hello World');" > hello.js
$ deno run hello.js
Hello World

Follow this guide to know more about DenoJS installation procedures and other processes.

The bigger picture: 

Why Deno? Are the problems with NodeJS so big that we need a new system? Well, no. Many people won’t even consider them to be problems, but there is a central idea behind Deno that makes its existence reasonable and design choices understandable:

Node deviates significantly from the browser’s way of doing things.

For instance, the browser will ask the user for permission when a website requests the right to capture audio. NodeJS did not have these kinds of permissions, but Deno reinstates them.

Even with the implementational specifics, this is the overarching theme. In order to reduce friction while transferring libraries from the front-end to the back-end or vice versa, DenoJS aims to be as near to the browser as possible. The status of the application as it was in Node has a significant impact on the overall picture, but Deno makes sure that the application has all the pertinent data required for application deployment.

Should you learn DenoJS?

Well, maybe, and maybe not. 

Deno may be a better option for new apps that don’t need to communicate with a lot of existing code. It is a production-ready technology with a comprehensive set of integrated development tools and a large standard library to support it. With Deno, you can develop the functionality of your application more quickly by utilizing tools like TypeScript while reusing a larger amount of your work across many platforms.

Then what’s holding Deno back? Although Deno’s community is active, it is still quite small. Deno-specific packages are quite rare, and the NodeJS compatibility layer isn’t always reliable. This could leave you at a disadvantage if you want to use a particular library or if you need some support. 

Deno will get better with time as it gets more and more compatible with NodeJS. So until then, keep an eye out.

Conclusion: 

To put it mildly, Deno is an interesting project. We only have the initial stable version, and there is still much work to be done. For instance, they are working diligently to enhance the TypeScript compiler’s performance. In addition, the ‘—unstable’ parameter hides many APIs. The upcoming releases could alter these. Deno is a project worth following because of the principles like TypeScript’s first modules that work in browsers.

In this article, we will analyze whether the use of Object-Oriented Programming (OOP) concepts in JavaScript is viable.

Before getting started with the discussion, let’s have a quick glance at what is JavaScript

JavaScript is a lightweight, prototype-based scripting language, which is widely used for building web pages. With the help of a few frameworks like NodeJs JavaScript can also be run in a non-browser environment like in any OS terminal. JavaScript is a single-threaded and dynamic language that can act as a multi-threaded language with the help of an event loop. But does JavaScript complies with Object Oriented concepts?

Is JavaScript Object Oriented?

The answer to the above question is Maybe. The reason is that still there are discussions that if JavaScript is OOPS or not. Some people tend to suggest that it’s not at all Object-Oriented as it does not support classes just like Java does, though some suggest that it has the properties of OOPS and so it is an object-oriented language. Let’s first discuss what are the properties of Object-Oriented language.

The THREE pillars of Object Oriented Programming:

Polymorphism, Encapsulation, and Inheritance — These are the three properties that define if any language follows OOPS laws or not. Let’s go through each one of them quickly –

Polymorphism:

Poly — many, Morphs — forms Polymorphism means anything with many forms. To elaborate with the simplest example given below:

In the above examples, we have used the + operator where in example 1 it simply adds the two numbers while in example 2 it concats the strings a and b. This explains that JavaScript does follow the laws of Polymorphism.

Inheritance:

Inheritance means that the child class can be derived from the parent class having all the properties of the parent class and also some additional properties of its own.

JavaScript follows a concept of prototype inheritance which let objects access all or some properties from other objects or parent objects.

The above example shows how the object car can not only access its own properties brand and type but also the property of the parent Object like hasOwnProperty. This explains how JavaScript is able to achieve inheritance with a fair means.

Encapsulation:

Encapsulation is nothing but hiding the private data or the data that should not be directly accessible. Now does JavaScript support the last pillar of OOPS?

Yes, it does, through the concept of scoping. Check the example below to understand better

As seen in the above example, the variable declared inside the function functionExample can be used inside the same function only and are not accessible outside the function. This means that JavaScript also follows the laws of encapsulation.

To dive deep into the topic refer to this article.

The conclusion

As we have discussed above, is JavaScript an Object-Oriented language?

I would say YES, though JavaScript does not support classes (We have the class syntax in ES6 though it’s just function sugar coating, as we know ES6 is transpiled to ES5, and the classes are transpiled back to functions) still JavaScript follows all the three properties of Object-Oriented language. And according to the above discussion, I will also agree with the point that any language can be Object-Oriented even though it does not support classes.

The DevOps model or the DevOps lifecycle constitutes eight phases: plan, code, build, test, release, deploy, operate, and monitor. Their further division is:

1. Continuous Development (Plan and Code)

2. Continuous Integration (Build and Test)

3. Continuous Deployment (Release and Deploy)

4. Continuous Monitoring (Operate and Monitor)

What is Azure DevOps?

Now that we have a basic understanding of what DevOps is let’s understand Azure DevOps. 

It is a single platform that helps every software development team to design software. By utilizing the Agile process, developers can oversee code Git, test the application, and deploy code using the CI/CD framework. 

Azure DevOps (previously known as VTST) handles DevOps, successfully. Azure DevOps automates all development and operations processes. The technology stack and tools in this are reliable, evolve quickly, and help engineers to accomplish tasks quickly. Like establishing cloud infrastructure for application deployment or continuous deployment of code from GitHub using Visual Studio Team Services. Usually, these tasks would have required assistance from separate teams, but because Azure DevOps integrates these into a single unit, it increases the development speed. 

Azure DevOps Service Vs. Server

Azure DevOps is available in two different ways: on-premises (“Server”) and online (“Services”). 

Azure DevOps Services is released by Visual Studio Team Services and, Azure DevOps Server is released by Team Foundation Server. The cloud service belongs to the Microsoft Azure cloud platform. In this blog, we will be talking about Azure DevOps Services. 

Terminology in Azure DevOps:

1. Continuous Integration: Continuous Integration (CI) is a method that automates the build and testing of code every time a team member pushes a change to version control. The master branch remains clean with the creation of a development branch. After the completion of testing and the acceptance of the pull requests, changes take place in the master branch.

1. Continuous Delivery: Continuous Delivery (CD) is the process of building, testing, configuring, and deploying software from a development environment to a production environment.

1. Infrastructure as Code: Infrastructure as Code (IaC) is the management of infrastructures like networks, virtual machines, load balancers, and connection topology in a descriptive model, using the same versioning as the DevOps team uses for source code. DevOps team can test applications in production-like environments early in the development cycle in Infrastructure as Code.

1. Microservices: Microservices are architectural patterns in which programs are broken down into smaller components and deployed to carry out specific business logic. Communication over the web occurs with Azure DevOps REST API.

Benefits of Azure DevOps

Azure DevOps combines the cloud with DevOps. It allows the team to develop, deploy, and monitor code without opening multiple interfaces. Below are a few benefits:

1. Speed: The code automatically builds and tests for errors and bugs after execution. This allows the team to take ownership of services and release updates faster. 

1. Speedy Delivery: Since all the processes and tools are on the cloud, the development and testing of apps can be done using automated tools and deploying as soon as a code commit happens. This facilitates rapid delivery.

1. Reliability: You are informed of the performance in real-time with the help of monitoring and logging practices

1. Scaling: Infrastructure as code enables you to manage your development, testing, and production environments more consistently and efficiently.

1. Improved Collaboration: Teams can collaborate effortlessly with DevOps on a single unified platform for developers and operations. They are no longer separated from one another and can now share tasks and feedback. 

1. Security: Scalable compliance may be defined and tracked using automated compliance policies, fine-grained controls, and configuration management techniques.

Types of Services

Azure Boards: 

The Azure board is used for project planning, work item tracking, backlog management, and sprint management. Azure Board is an ALM (application life cycle management) tool, similar to JIRA, SpiraTeam, and others. One can create workflows, issue types, epic, and many other components of ALM inside the Azure board.  IT consists of three types of work items: 

Epic work item: It tracks features or any requirements.

Issue work item: It tracks bugs or any small changes.

Task work item: It tracks works that are smaller than that tracked by issue.

Azure Repos

Azure Repos allows users to create, manage, and store code versions. It can be used for code review as well as other version control features. GIT (distributed version control) and TFVC are the two types of version control systems that Azure Repos provides.

Azure Pipelines

The Azure pipeline is a DevOps automation process that allows us to produce, release, test, and deploy code to the target machine. In simple terms, the Azure pipeline is a combination of CI/CD. 

Azure Test Plans

Advanced test management solutions for client feedback, UAT, automation testing, and manual testing are all supported by Azure test plans.

Azure Artifacts

Azure Artifacts is one of the Azure DevOps extensions. All the artifacts produced during development and deployment are stored here.

It allows the team to create, host, manage and share packages. Packages such as NPM, Nuget, Maven, Python, and others are supported by Azure Artifacts. 

Life-cycle

This life cycle mainly follows the below-mentioned phases:

Write code, test, and debug:

Most Azure application code is written locally on a developer’s machine throughout the application development stage. Azure Functions, a new service from Microsoft, has recently been added to Azure Apps. Azure Functions is a serverless computing technology. It allows developers to create enterprise apps without having to write code or maintain infrastructure.

Deploy and Monitor:

For Deployment and Monitoring, Visual Studio Team Services and Git are two popular code collaboration tools. Azure App Service for DevOps provides OneDrive, Dropbox, FTP, Local git repository, Github, and Visual Studio Team Services deployment slots for Continuous integration and deployment of your codebase

Why migrate to Azure DevOps services

Below listed are a few reasons why you won’t regret switching from on-premise to Azure DevOps services.

1. Automatic Updates

2. Cost and time effective

3. Compliance Certifications

4. Access any device from anywhere

5. 99.9% Uptime

Conclusion

With the number of actual DevOps applications growing all the time, Azure DevOps has a great future.  Many things, however, would alter and better as a result of this. A lot of applications running from the cloud could bring a significant shift in the world of DevOps! Choose your cloud service provider today.

So here, let’s discuss the history of programming languages and a few of the oldest programming languages in history. 

“Did you know: Ada Lovelace invented the first-ever machine algorithm for Charles Babbage’s Difference Machine that laid the foundation for all programming languages.” 

Ada Lovelace invented this in 1843. She wrote this machine algorithm on a piece of paper!

Her machine language algorithm laid the foundation for programming languages.

Later in 1944, Konrad Zuse developed the first ‘real’ programming language called Plankalkül. In 1949, there came assembly language, a low-level programming language that simplified the language of machine code. John McCauley suggested Shortcode, the first High-Level Language. In 1952 Alick Glennie developed the first-ever compiled language. Using a compiler, this language could be translated into machine language. 

After this came a few important programming languages, which are the oldest ones and are still in use today.

1. Fortran

In 1957, John Backus designed and a team of developers from IBM under his leadership developed Fortran. It is the oldest programming language in use today. Backus first submitted the proposal for the language in 1953. In the later stages of its development, it was used on the IBM 704 mainframe computer.

Fortran IV and Fortran 66 are the two versions of Fortran which are still in use. Fortran 77, Fortran 90, and Fortran 95 are the most used versions. 

Major Implementations: Absoft, Cray, GFortran, G95, IBM XL Fortran, Intel, Hitachi, Numerical Algorithms Group, Open Watcom, PathScale, PGI, Silverfrost, Oracle Solaris Studio, Visual Fortran

2. Lisp

Lisp is a family of programming languages. Released in 1958, designed by John McCarthy and developed by Steve Russell, Timothy P. Hart, and Mike Levin. It is the second oldest programming language still in use today. The design of this programming language was for easy manipulation of data strings. The best-known general-purpose Lisp languages are Racket, Common Lisp, Scheme, and Clojure.

Major Implementations: Racket, Common Lisp, Scheme, and Clojure

3. COBOL

In 1959, COBOL(Common Business Oriented Language) was released. Dr. Grace Murray Hopper was the developer of this language. Credit card processors, ATMs, telephone, and cell calls used to use this. Banking systems still use this language.

Major Implementations: GnuCOBOL, IBM COBOL, and Micro Focus Visual COBOL

4. BASIC (Beginner’s All-Purpose Symbolic Instruction Code)

The BASIC programming language was released in 1964. It was designed and developed by Dartmouth College students John G. Kemeny and Thomas E. Kurtz. As the language was easy to learn, it became popular among students who weren’t good at mathematics or computers. 

This language was further developed by Microsoft and became the first marketable product of the company.

Major Implementations: Dartmouth BASIC,  Applesoft BASIC, Atari BASIC, Sinclair BASIC, Casio BASIC, Microsoft BASIC, Liberty BASIC, PowerBASIC

5. Pascal

Niklaus Wirth in 1970 developed and designed PASCAL. This programming was popular among the students who were interested in improving their programming skills. It included good programming practices using structured programming and data structuring. In the late 1970s and 1980s, commercial softwares were written using Pascal.

Major Implementations: CDC 6000, Embarcadero Delphi, ICL 1900, Pascal-P, PDP-11, PDP-10, IBM System/370, VSI Pascal, Free Pascal, GNU Pascal

6. C

Dennis Ritchie in 1972 developed C. It was developed to use with the Linux operating system.  C is based on an earlier language called “B”. Languages like C#, Java, JavaScript, Perl, PHP, and Python are all derivatives of C. Tech giants like Google, Facebook, and Apple still use C. 

Major Implementations: K&R C, GCC, Clang, Intel C, C++ Builder, Microsoft Visual C++, and Watcom C

7. Smalltalk

1972 saw the release of Smalltalk. Alan Kay designed and Xerox Palo Alto Research Centre by Alan Kay, Adele Goldberg, and Dan Ingalls developed Smalltalk. Its commercial release was in 1980.  Before this, only Xerox Alto computers ran this.

Major Implementations: Amber, Dolphin Smalltalk, GemStone/S, GNU Smalltalk, Pharo, Smalltalk/X, Squeak, VA Smalltalk, VisualWorks

8. SQL(Structured Query Language)

SQL, designed by Donald D. Chamberlin and Raymond F. Boyce and developed by IBM, was released in 1974. The purpose of SQL was to manipulate and retrieve data stored in IBM’s database management system.

Major Implementations: Amazon Aurora, Database Management Library, Google Fusion Tables, IBM DB2, IBM Lotus Approach, Microsoft Access, OpenLink Virtuoso, Oracle, and many more

These are the few oldest programming languages that are still in use. Apart from these, there have been many programming languages, to name a few :

Ada: 1980

C++, Ruby, Objective C: 1983

Perl: 1987

Haskell: 1990

What is Cloud-Native?

Ask ten different people and you will receive ten different answers.

So, according to Cloud-Native Computing Foundation’s official definition:

“Cloud-native technologies empower organizations to build and run scalable applications in modern, dynamic environments such as public, private, and hybrid clouds. Containers, service meshes, microservices, immutable infrastructure, and declarative APIs exemplify this approach.

These techniques enable loosely coupled systems that are resilient, manageable, and observable. Combined with robust automation, they allow engineers to make high-impact changes frequently and predictably with minimal toil.”

Developing an application has become very complex with users demanding more and more and better UI/UX. Users expect rapid responsiveness, innovative features, and zero downtime. Problems with performance, errors, or speed are no longer acceptable.

Businesses now focus on strategic transformation that can speed up business velocity and growth. Cloud-native is all about that speed and agility. Selling an idea to the market has become more crucial. 

Companies like Netflix, Uber, WeChat have achieved great pace, agility, and scalability with this.

“Netflix has 600+ services in production. Deploys hundred times per day.”

This architecture enables these companies to respond to market conditions. They can immediately update small areas of a live, complex application, and scale those areas as required.

This blog series will tell you all you need to know about what cloud-native is and why it matters. There are three parts:

• Cloud-native architecture: what is it and why does it matter?
• Cloud-native development: how does the cloud change how you develop?
• Principles and practices for Cloud-native: tips on how to go ahead on cloud

In this blog, we will be discussing Cloud-Native Architecture.

Cloud-Native Architecture: What is it and why does it matter?

What is Cloud-Native Architecture?

An architecture or a system built to exist and run in the cloud is a cloud-native architecture. Unlike legacy systems, cloud systems don’t rely on hardware and software. Flexibility is one of the main advantages of this architecture.

Cloud-native architectures are deployed on a cloud platform. It leverages the cloud philosophy of distributed systems. This thus enables these architectures to take full advantage of the latest and best technologies around distributed systems.

The cloud-native architecture utilizes cloud services such as EC2, S3, Lambda from AWS, etc. to allow dynamic and agile application development. Microservices are at the core of cloud-native application architecture. Each microservice is made to execute a different function, whether implementing capabilities, communicating, or running processes.

Why Is this Architecture Important?

Cloud-native removes constraints and shortens the path to business value.

Let me explain with an example.

You have a payment application and, the user feedback for your app suggests that users want a passbook feature in the app.

Now, without cloud-native, you will start by thinking, how to deploy, what network you need, and, you will think about the customer.

But this setup removes the need for servers, operating systems, orchestration layers, and networking which, puts your code front and centre of everything. Your team can straight away try out and experiment with things.

Cloud-native removes the constraints of “what if we did this?” With this, you focus more on the products and not pipelines. Fix errors in your app and not in your database replication.

The Benefits of Cloud-Native Architecture

~ Removes Constraints to Rapid Innovation

The traditional systems are slow to adapt and at times are inflexible to the changing needs. But, with this architecture, the software delivery pipeline has undergone a huge transformation. Be it with build automation, test automation, or deployment automation.  In DevOps, the automation is done across the software delivery process.

~ Brings You Closer to the User

The key benefit of cloud-native is eliminating non-customer-focused activities. The closer developers are to the users, the better understanding they have of the product. 

Customers these days expect a rapid release. Cloud-native architecture lets you roll out features to a small percentage of your users, where you can test prototypes with actual customers in real-life situations.

~ Cost-effective

In the cloud, you only pay for what you use and don’t have to buy anything up front. Rather than using infrastructure, containers are used in cloud-native which are easier to manage and secure applications. Kubernetes is used for managing resources in the cloud. Kubernetes along with an open-source model and few cloud-native tools drives down costs. 

~ Easy Access to New Tools and Services

With the cloud, we have access to new tools and services. Cloud-native has many options to make infrastructure management effortless for example serverless platforms like Azure Functions and AWS Lambda.  

Serverless computing platforms let you upload code in the form of functions and the platform runs those functions for you so you don’t have to worry about provisioning cloud instances, configuring networking, or allocating enough storage.

~ Secure, Transparent, and Reliable

With modern cloud-native approaches like microservices architecture and Kubernetes in the cloud, you can easily build applications to be fault-tolerant with resiliency and self-healing built-in.

Because of this design, even if any failures happen you can isolate the impact of the incident. Therefore, it doesn’t take down the entire application.

~ DevOps and agile frameworks

For this approach, groups within IT and business lines need to collaborate.

Development teams must partner with IT operations and the lines of business to deliver needed business functionalities. This, therefore, leads to a shift in culture away from step-by-step monolithic development practices to a more collaborative, agile method. While new tools and technology can help start to break down the barriers that monolithic processes have created over time, a DevOps culture is predicated on collaboration.

But, businesses now face a higher risk of cybersecurity threats as a vast number of remote working employees have no protection from the company’s in-house IT security systems. For a variety of tasks, staff would use their device: linking to the company servers, accessing online accounts, dependence on email, and messaging networks to establish contact with their team.

So, to help you revise your cybersecurity strategies, and work securely here are a few best practices to maximize data security and prevent information from falling into the wrong hands while working remotely or from home.

1. Avoid Public WiFi services and use a professional and secured VPN service

People often tend to use public WiFi when working remotely. Public WiFi can have majorly two problems. Firstly, there is no firewall between you and other people connected to the same network which can give access to threat actors. Secondly, to secure the data transfer, it needs encryption before sending it.

If you have to work on public WiFi, you should use a VPN. It protects your traffic and provides a flexible connection to connect to different services.

2. Always keep work data on work computers

It is not safe to use a personal computer for work information. It puts the company networks and yourself at risk. Also, it can cause extensive corporate damage, and you become potentially responsible for it through violations of policy and practices.

While working remotely or from home, precautions like using your work computer, secure WiFi, a VPN, encrypted drives, anti-virus, and endpoint protection should be taken.

3. Encrypt Sensitive Data in Emails

When working remotely or from home, emails become the only source of communication. But sending emails with sensitive information can be risky as it can be accessed by an intruder. So, make sure that you always encrypt the data attached to an email. This ultimately prevents any unintended recipient from viewing the information.

4. Outsource to cloud-based services

All the necessary software, apps, and online services can be integrated into one single computation environment with the help of a cloud-based IT solution.

It becomes easier for employees to update and edit the data if data storage is at a unique location. Employees won’t have to rely on multiple third-party software. Cloud-based services are the most effective solution to reduce network vulnerabilities when working remotely.

5. Train employees on security risks

Data breaches are often caused by human mistakes. When the employees are working remotely or from home, the IT team will have to build new guidelines focusing on online threats.

Train and educate your staff about cyber attacks and their signs. For instance, slowing down of the computer, unusual pop-ups appearing on screen, or losing control of the mouse or keyboard. Provide employees with clear guidelines on what can and cannot be shared. 

6. Use a Mobile Device Management solution

An MDM solution provides enterprises with the ability to manage and track smartphones, laptops, or tablets and to ensure that each system is complying with company protocols. 

For configuring configuration, upgrading operating systems, downloading applications, and collecting location data, employees can have direct access to each device. 

This solution aims to ensure that while working remotely no unapproved applications are used that may damage the data stored in the device.
