DevOps

DevOps is a set of practices that combines software development (Dev) and IT operations (Ops). It helps organizations build, test and release software faster and more reliably.

Version control tracks changes in code and allows teams to collaborate.

• Repository – project storage
• Commit – saved change
• Branch – parallel development
• Merge – combine changes

CI/CD automates building and deploying applications.

• Continuous Integration – automatically test code
• Continuous Deployment – automatically release updates

Docker packages an application with all dependencies into a container. This ensures the application runs the same on every system.

Kubernetes manages multiple containers, scales applications and keeps services running automatically.

DevOps uses monitoring tools to track system health.

• Logs – system activity records
• Metrics – CPU, memory, traffic
• Alerts – notifications when errors occur

• Faster software delivery
• Less downtime
• Automatic updates
• Improved reliability
