Excellent question! Let me explain it in a simple manner.
What is DevOps?
DevOps is a merge of Development (Dev) and Operations (Ops) practices that seek to release software faster, more reliably, and with ongoing improvement.
It's not a tool—it's a culture, process, and practice set.

Plan
Teams plan new features, bug fixes, or enhancements.
Tools: Jira, Trello, Azure Boards
Code
Developers create and maintain source code in repositories.
Tools: Git, GitHub, GitLab, Bitbucket
Build
Code is compiled, packages dependencies, and generates artifacts.
Tools: Maven, Gradle, Jenkins, GitHub Actions
Test
Code quality and functionality are tested by automated tests.
Tools: Selenium, JUnit, pytest
Release
Released builds are made ready to be deployed.

Deploy
Code is deployed on servers, containers, or cloud infrastructures.
Tools: Docker, Kubernetes, Ansible, Terraform
Operate
The application is run in production, which is monitored for performance and errors.
Tools: Prometheus, Grafana, ELK Stack
Monitor & Feedback
Metrics & logs are scrutinized to enhance the product on a continuous basis.
Tools: Splunk, Datadog, New Relic
DevOps Core Practices
CI/CD (Continuous Integration / Continuous Deployment): Regular, automated releases.
Automation: Eliminates human errors and accelerates delivery.
Infrastructure as Code (IaC): Servers & networks controlled using code (Terraform, Ansible).
Collaboration: Dev & Ops collaborate, demolishes silos.
Monitoring & Logging: Guarantees high availability and rapid recovery.
