How many practices/methodologies are there in DevOps?

In DevOps, there are several key practices and methodologies that help integrate development and operations:

1. Continuous Integration (CI) — automating the build and testing of code with each change.
2. Continuous Delivery (CD) — automating the release of changes to testing and production environments.
3. Infrastructure as Code (IaC) — managing infrastructure through code and automation.
4. Monitoring and Logging — continuously collecting metrics and logs for quick problem detection.
5. Automated Testing — integrating automated tests at all stages.
6. Culture of Collaboration — uniting development and operations teams for shared responsibility.

These practices are interconnected and together ensure fast and reliable software delivery.
