DevOps CI/CD Tools (frameworks)

Nowadays, speed and quality have become the new norm of the software industry, propelling the need for the adoption of new development methodologies and cultures like DevOps and agile. DevOps, with its agile, continuous, and automated delivery cycle, enables enterprises to rapidly meet the changing demands and accelerate the delivery of reliable and quality software.

Moreover, DevOps’ CI/CD concepts embody a set of operating principles and practices that enable teams to deliver code changes more frequently and reliably. However, teams need proper Continuous Integration and Continuous Delivery tools for effective DevOps and CI/CD workflow implementation. These tools allow developers to focus on meeting business requirements, code quality, and security as they automate the entire development and deployment pipeline.

Since the market is overflowing with CI/CD tools, deciding on the right set of tools is an ever-growing challenge for the teams involved. Therefore, here is a list of some of the most prominent and powerful CI/CD tools currently in use worldwide.

Before we move on to listing CI/CD tools, let us first understand:

What is Continuous Integration & Continuous Delivery (CI/CD)?

A DevOps and agile methodology best practice, Continuous Integration & Continuous Delivery/Deployment (CI/CD), automates the development, deployment, and testing process, enabling enterprises to deliver quality applications and code to users.

Moreover, it introduced ongoing automation and continuous monitoring throughout the development lifecycle, from the development and integration stages to testing, feedback, delivery, and deployment.
