DevOps is a practice or culture adopted by organizations. It's a culture that improves the delivery of applications. For example, if example.com encounters any issues, normally it takes 10 days to fix and deliver. With DevOps, we can deliver it in hours or 1-2 days based on the bug.
DevOps is all about:
What is DevOps?
DevOps is a process of improving the delivery of any application by ensuring proper automation, code quality, continuous monitoring/observability, and continuous testing.
Staging Environment - Pre-production
Why DevOps?
Ten years ago, we had system administrators who created server environments, server administrators who deployed the app server in server environments, and build and release engineers who deployed the code in servers, which was then tested by testers. The code was stored in a central location by developers. It was slow because everything was done manually. That's why DevOps came into play and emerged. To improve the process of delivery and its organizational efficiency in delivery.
