Nice question Let's break it down in simple terms:

What is DevOps?

DevOps = Development + Operations

It's a culture + set of practices + tools that unites developers (who code) and operations (who operate/maintain systems).

The objective:

Deliver software faster

With better quality

And less downtime

Rather than devs coding and "throwing it over the wall" to ops, both collaborate using automation and shared accountability.

How DevOps Functions (Workflow)

Consider DevOps to be a cycle (referred to as the DevOps lifecycle):

Plan

Teams schedule features, bug fixes, and enhancements.

Tools: Jira, Trello, Azure Boards.

Code

Developers write and version the code.

Tools: Git, GitHub, GitLab, Bitbucket.

Build

Code is compiled into applications (packaged).

Tools: Jenkins, Maven, Gradle.

Test

Automated testing is executed to identify bugs early.

Tools: Selenium, JUnit, PyTest.

Release

Approved code is automatically deployed using pipelines.

Tools: Jenkins, GitHub Actions, GitLab CI/CD.

Deploy

Code is deployed into production (servers, cloud, containers).

Tools: Docker, Kubernetes, AWS, Azure, GCP.

Operate

The app is deployed in production, and it serves users.

Tools: Kubernetes, cloud services, config managers (Ansible, Puppet).

Monitor

Teams monitor constantly for performance, bugs, and user feedback.

Tools: Prometheus, Grafana, ELK Stack, Datadog.

Example: How DevOps Works in Real Life

Think of Netflix:

Developers implement a new recommendation feature

Code is in GitHub.

Jenkins automatically builds and tests it.

Monitoring tools verify whether users experience errors or slow streams.

In the event something goes wrong, teams roll back with speed through automation

Outcome: Users receive new features earlier, without Netflix crashing.

✅ Briefly:

DevOps is all about teamwork, automation, and continuous delivery.

It happens in a cycle of planning, coding, building, testing, releasing, deploying, operating, and monitoring
