What is DevOps?

DevOps — one of the key pillars of tech modernization which involves a cultural transformation with a blend of agility and stability. DevOps leverages people, processes, and technology to foster collaboration and innovation across the entire application development life cycle.

DevOps helps to manage the challenges by automating code management, integration, release management, testing, and deployment in a seamless fashion.

What is CI?CD?

DevOps involves collaboration via continuous integration and continuous deployment.

Either with microservice-based architecture or with monolithic applications with service layer, the need to manage heterogeneous applications are increasing reality for many organizations.

CI/CD bridges the gaps between development and operation activities and teams by enforcing automation in building, testing and deployment of applications.

Modern-day DevOps practices involve continuous development, continuous testing, continuous integration, continuous deployment, and continuous monitoring of software applications throughout their development life cycle.

The CI/CD practice or CI/CD pipeline forms the backbone of modern-day DevOps operations.

What is Jenkins?

Jenkins is a free and open-source automation server. It helps automate the parts of software development related to building, testing, and deploying, facilitating continuous integration and continuous delivery.

It is a server-based system that runs in servlet containers such as Apache Tomcat.

It supports version control tools, including AccuRev, CVS, Subversion, Git, Mercurial, Perforce, ClearCase, and RTC, and can execute Apache Ant, Apache Maven, and sbt based projects as well as arbitrary shell scripts and Windows batch commands.
