DevOps is an approach to software development that breaks down the walls between development (Dev) and operations (Ops) teams, creating a seamless fusion of processes and tools. The main goal of DevOps is to increase the velocity of delivering new features, fixes, and updates to customers while also increasing the reliability and stability of the systems.
To achieve these goals, DevOps relies on tools and practices such as continuous integration, continuous delivery, automation of infrastructure management, and monitoring. These tools and procedures allow organizations to automate parts of the software delivery process and make it more efficient while enabling teams to work more collaboratively and effectively.
DevOps is a way of working together to create and improve computer programs. Imagine you have two groups of people: one group writes the instructions (code) for the program, and the other group makes sure the program runs smoothly on computers. In the past, these two groups didn't always talk to each other very much, which sometimes caused problems and delays.
DevOps is like a teamwork strategy that helps these two groups work closely together, like a soccer team passing the ball to score a goal. They use special tools and techniques to share their work, fix problems quickly, and improve the program. When everyone on the team works together, they can create awesome computer programs that people love to use!
