Git's functionality, performance, security, and adaptability are desired by the vast majority of enterprises and individuals. It is also useful as a DevOps tool for distributed version control.
Service oriented architecture is a method of reusing software components by using service interfaces. In order to enable quick integration into completely new applications without the need for labor-intensive integration each time, these interfaces rely on widely used communication protocols. The service interfaces can be called without understanding how the integration is executed.

Docker
It is an open-source platform that is used to Create, Run, and Deploy applications with the use of containers. Contrarily, as firms utilise cloud and hybrid settings, containers have gained popularity because they make providing programmes easier. Docker makes it straightforward to do so, thus pre-made images can be downloaded from the Docker Hub. This not only saves time, but also aids in the creation of Java applications.
It is a free framework for programmers to test Java. JUnit allows developers to build and run a large number of tests, making it perfect for both beginners and specialists. The ability for developers to create custom test scenarios is the best feature. Erich Gamma and Kent Beck created it in the 1990s. In a 2013 poll, it was shown that out of 10,000 projects, JUnit was largely used for execution. It is very well-liked among geeks.
