What is DevOps?
DevOps is a combination of Development (Dev) and Operations (Ops). It's a cultural, philosophical, and technical movement that aims to:
•	Improve collaboration between software developers and IT operations teams.
•	Automate the process of software delivery.
•	Increase the speed, quality, and reliability of software development and deployment.
Core Principles of DevOps
1.	Collaboration – Developers and operations work together.
2.	Automation – CI/CD pipelines, testing, deployment.
3.	Continuous Improvement – Regular feedback and iteration.
4.	Monitoring and Feedback – Constant tracking and analysis of performance.
5.	Security – Shift-left approach to integrate security early in the cycle (DevSecOps).
DevOps Lifecycle
The DevOps lifecycle consists of the following stages:
1.	Plan – Define business requirements and goals.
2.	Develop – Write the code.
3.	Build – Compile and integrate the code.
4.	Test – Run automated tests to ensure quality.
5.	Release – Deploy to production.
6.	Deploy – Deliver updates frequently and reliably.
7.	Operate – Monitor and maintain infrastructure.
8.	Monitor – Track performance, logs, and incidents.
