Git & GitHub for DevOps: Version Control Mastery

Step 4 of the DevOps Roadmap

DevOps teams usually practice "git ops" i.e. making changes to any operations related activity require a pull request against a git repository. Learn about git, create your GitHub profile. Create and deploy some application to AWS.

Why Git & GitHub for DevOps?

Version control is essential for DevOps because:

• Infrastructure as Code requires versioning
• Collaboration across development and operations teams
• Change tracking and rollback capabilities
• Automated deployments triggered by Git events
• GitOps methodology for infrastructure management
