DevOps & CI/CD · Module 1 of 10

What is DevOps?

DevOps joins development and operations to ship software faster and more reliably.

📖 Key ideas

DevOps is a culture plus practices: collaboration, automation, measurement, sharing.
Breaks the wall between developers (change) and operations (stability).
Lifecycle: plan → code → build → test → release → deploy → operate → monitor.
Automation reduces manual errors.
Goal: small, frequent, safe releases.

💡 Real-life example: DevOps is a relay team that trains together instead of throwing the baton over a wall.
