The entire DevOps course is based on AWS Environment.

Jenkins is an open-source automation tool written in Java with plugins built for Continuous Integration purposes.

It can be used to automate almost anything.

Go faster and learn how to build strong automated processes like Pipelines, CI/CD Workflow, and more!

In this course module, you will learn in addition to Jenkins, crossing technologies that go hand in hand with this service, such as Docker, AWS, Ansible, Git, Maven, Gradle, Pipelines, and many more!
