Hello guys, you may know that Python is a multi-purpose programming language meaning that you can use it in different fields such as GUI application, artificial intelligence, and web application, and much more, just to name a few. Apart from Data Science, Web development is another area where Python really shines because of its awesome tools, libraries, and frameworks. And, when we talk about web applications, one of the best python frameworks that are popular is the Django framework which allows you to create a Python web application very quickly and easily.

Top 5 Free Courses to learn Node.js in 2020 - Best of lot
Node JS has completely changed the way JavaScript is used for development. Earlier JavaScript was considered as a client-side language because it runs on a browser and mostly used for client-side validations, animations, and interaction. Node.js takes that to the next level by allowing JavaScript to run on a server-side, which means you can now write JavaScript applications that can execute without a browser. Node JS uses Google Chrome's execution engine and asynchronous processing to do this. All you need to is include node.js script in your application, and you are ready to create server-side applications in JavaScript, which wasn't possible until a few years back.
Top 5 Spring Cloud Annotations for Java and Microservices Developers
If you are developing a Java application for Cloud, then you should learn Spring Cloud, a great framework and extension of the popular Spring framework, which can help you to develop a cloud-native Java application. Spring Cloud provides several necessary services required for a cloud-based Java application like configuration management, service discovery, circuit breakers, intelligent routing, micro-proxy, a control bus, one-time tokens, global locks, leadership election, distributed sessions, cluster state, etc. On top of that, it builds on the Spring framework, so it automatically provides essential features like dependency injection and inversion of control, which results in loosely coupled and easy to test Java application.
