What is cloud computing? Cloud computing is the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet (“the cloud”) to offer faster innovation, flexible resources, and economies of scale. Cloud computing is very important as it allows people access to the same kinds of applications through the internet. … This means the device accessing the cloud doesn’t need to work as hard. By hosting software, platforms, and databases remotely, the cloud servers free up the memory and computing power of individual computers. Benefits of cloud computing :

PYTHON AND AND ITS FRAMEWORK
Django is a free and open source web application framework written in Python. A framework is nothing more than a collection of modules that make development easier. They are grouped together, and allow you to create applications or websites from an existing source, instead of from scratch.
This is how websites – even simple ones designed by a single person – can still include advanced functionality like authentication support, management and admin panels, contact forms, comment boxes, file upload support, and more. In other words, if you were creating a website from scratch you would need to develop these components yourself. By using a framework instead, these components are already built, you just need to configure them properly to match your site.
The Official Project Site describes Django as “a high-level Python Web framework that encourages rapid development and clean, pragmatic design. Built by experienced developers, it takes care of much of the hassle of Web development, so you can focus on writing your app without needing to reinvent the wheel. It’s free and open source.”
Django offers a big collection of modules which you can use in your own projects. Primarily, frameworks exist to save developers a lot of wasted time and headaches and Django is no different.
Django was created with front-end developers in mind. “Django’s template language is designed to feel comfortable and easy-to-learn to those used to working with HTML, like designers and front-end developers. But it is also flexible and highly extensible, allowing developers to augment the template language as needed.”
If you’re going to be working with Python, especially for web applications or web design, you’ll want to remember the Django framework. It will certainly come in handy.
CherryPy is another Python-based framework that is great to work with, although it is designed with the absolute minimalist in mind. It’s a framework you’ll want to explore after you already have some experience working with Python.

The popularity of Java script grows every day. It’s definitely the best scripting language which allows creating exciting interfaces and simplifies the development of web applications, being a perfect open source app development software and making the sites interactive and convenient to use.
The Javascript web development frameworks are issued and updated daily and that’s why it is difficult at times to go with the tides and understand which famework is most suitable and best matching for the project.
Before choosing a web app framework to apply the requirement and needs of the project to be taken into consideration.
The advantages of the frameworks
Javascript framework is a number of features and functions written in Javascript language and ready for the usage of the developers. These features simplify the interaction between the app and server and speed up the manipulating of the web page or app elements.
The main advantage of using a web application development frameworks is the fact that it provides immediate reaction to the user interacting with the site immediately.
The basic content of the traditional sites without frameworks is stored on the server and any new content , which is necessary to be upload requires reloading of pages. When frameworks are used , only the necessary blocks of a website are reloaded.
Some of the most advantageous benefits of the frameworks ‘usage:
- COST: The cost of the app development for websites decreases due to the JavaScript frameworks because they are free and open source code.
- Development speed: Java Script frameworks have good documentations. Some of the JavaScript frameworks are supported by such giant companies as Google etc. Due to such a lot of information, the speed of development increases.
- Efficiency: The usage of the pre-created functions and templates allows to carry out the projects more effectively. The developers have to write less code, which results in delivering projects meeting higher standards and more quickly.

Angular 9 is the most preferred framework for creating interactive components of a website. It was designed as a full-featured JavaScript framework to enhance simplicity and efficiency. Developers find AngularJS very effective especially in creating dynamic, single page apps, and supporting MVC (Model View Controller) programming structure. As the business environments become highly competitive, AngularJS has emerged as the super hero because of its intuitiveness and rich features.
The popularity of Angular 9:
Today, AngularJS is one of the frameworks that do not make the Model View Controller look skewed and together along with NodeJS, it simply works great with both the technology understanding same notations. Some frameworks simply bundle together the existing tools which make app development very difficult. However, AngularJS was carefully engineered to ensure that every tool works optimally and delivers great results.
After its release in 2009, AngularJS popularity has grown steadily and shows no sign of slowing down. But why is Angular becoming so popular and surpassing other frameworks? Here are a few samples of developers’ views after using the app.
Pros of Angular Apps:
When AngularJS 4 was released in March 2017, it made JavaScript to be named the best programming language of the year. The regular Angular updates have particularly made developers, and users get a special attachment to their apps because of enhanced security and features. Here are additional pros of Angularapps.
Time-saving: Projects that previously used to take many months with other frameworks can now be completed faster with AngularJS. All that AngularJS framework requires is splitting the app into several MVC components. From there, the framework takes over because you do not require additional coding.
The app is easy to learn and get started: Getting up and running with AngularJS is perhaps the simplest thing a developer can imagine. Simply include some attributes into the HTML, and you can complete the first app in a couple of minutes.
Data Binding in AngularJS is very easy: Can you remember trying to create a text property on a model that requires binding to your app UI? It is very difficult with most frameworks. That stress has been eliminated in AngularJS. In fact, you can see the ultimate results as you type in the span.
Affordability: Because AngularJS is an open source framework, developers can come up with custom apps at lower costs.
The main features of Angular 9:
The main reason that AngularJS has gained a lot of popularity is its unique features. The features make app development easy and result very intuitive. These features include;
Two-way data-binding: Data binding is one of the most notable AngularJS features. This feature helps save the developer from doing a lot of coding. In any app, 80% of the code base is dedicated to manipulating, traversing, and listening to DOM. However, data-binding in AngularJS helps to reduce the work so that the developer can concentrate with the app.
Ready to use templates: The AngularJS is simply plain HTML. The browser parses these templates into the DOM and transforms it to AngularJS compiler. Then, the AngularJS Framework traverses the templates to get rendering instructions called directives. The ready to use templates make it easy even for people with little computing skills come-up with great apps.
Dependency injection: This is an essential feature in AngularJS that makes the developer able to ask for dependencies as opposed to making them on his own. Think of this feature as a way of saying I need X and not starting to make X.
Testing feature: The AngularJS developer team worked with special focus on testability in mind. This means that you can easily test AngularJS apps.
AngularJS has started with version 1.0 and make so many positive changes when it comes to version 1.3 but there are some glitches regarding security in version 1 but when it comes with version 2.0 most of the problems are solved because in version 2.0 they have made so many good changes regarding security.AngularJS supports on fast and modern browsers such as chrome , Firefox , Opera , Internet Explorer 8 , Android , iOS6+ so we can work without any hesitation on AngularJS.
It’s one of the most popular JavaScript framework by which you can implement the things what JSP and another most of the technologies front frameworks implements.
Earlier days, the many frameworks were boom but When angular came into picture, it was a blast. As a developer I can surely say that in future any technologies having JavaScript as a base will not die. And recently AngularJS 2.0 is launched.
This framework gives a lot of things easy and it has number of features you can get it from it’s official website. And the funny thing is that if you know JavaScript and Jquery then there is no more efforts to learn the things.
The most awesome things you will love Two Way Data Binding and MVC Architecture.
Job opportunities hiring for Angular 9 Developers :
1. Major reason behind this is the trend of Startups in India and majorly startups are ready to use new frameworks and AngularJS & React both are among the most used UI frameworks.
2. With Google backing Angular, it has evolved as an excellent framework for UI development. One with proper functional knowledge of the framework can do wonders and make an application scalable, faster with very less effort.
3. 2-Way Data Binding, Templates, Routing, SPA. All these make AngularJS stand strong against other frameworks.
Moral of the Story: It is worthy. In market there is high demand for the AngularJS but the knowledgeable developers are less as compare to demand.
