DevOps Fundamentals: Breaking Down the Culture, Tools, and Practices

What is DevOps?

DevOps is a culture that improves the organizational ability to deliver the application.

Let me give you an example: Imagine an issue on shubhams.dev. Once the development team fixes the problem, the DevOps practices ensure that the changes can be deployed quickly and reliably to production.

Usually, people think, DevOps <--> CI/CD(improving delivery). In fact, DevOps is Improving Delivery, but it consists of many different things.

DevOps is a process of improving application delivery by ensuring there is proper automation in place, quality maintenance, continuous monitoring an continuous testing.

Why DevOps?

So, many years ago when DevOps was not there then the process was much tedious, explain below👇

System Admins -> They used to create servers

Developer -> They put the code to some central location(Servers / VM ware)

Tester -> They used to test the application which is present on the server

BRE(Build and Release Engineer) -> They take forward to production or pre-production

This process took too much time because of the different teams. So, After DevOps, this process became fast and smooth

How to introduce yourself?

Mention your developer experience, Other experience also like system admin, BRE, server admin, java dev, python dev etc. Also mention What you did, for example - automation check, quality check, monitoring of application, testing etc. You should also mention the tools you were using like GitHub Action for CI/CD, Kubernetes for container orchestration, Ansible, Terraform etc.
