DevOps is a culture and practice that promotes collaboration between development and operations teams, leading to faster software delivery with better quality and reliability.
The DevOps lifecycle includes planning, development, continuous integration (CI), continuous delivery (CD), and monitoring. Tools like Jira, Git, Jenkins, and Prometheus are commonly used in these phases.
Key principles of DevOps include collaboration, automation, measurement, and continuous improvement. Popular DevOps tools include Git, Jenkins, Ansible, Docker, Prometheus, and Grafana.
DevOps best practices include infrastructure as code (IaC), microservices architecture, and security integration. Challenges in DevOps implementation include resistance to change, tool overload, and skill gaps.
