DevOps is the combination of software development and operation; This is a set of practice used to ensure continuous integration and delivery.
The DevOps landscape continues to evolve with a growing number of tools supporting faster delivery, stronger security, and better automation.
Tools are used to automate all the processes and configurations that plays an important role in DevOps.
This process of optimization is also known as DevOps automation, but it has garage full of tools like CI/CD systems, testing frameworks, monitoring tools, and security audit tools….. So numerous tools have been developed to make the process easier.
To help you out, we have come up with the list of open source devops tools.
