![Add a heading (4)](https://hackmd.io/_uploads/H1kB9VnGxg.png) 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.
