2. When we need this use case

1. Rolling Update: When you need to gradually update your application without downtime, ensuring consistent availability.

2. Canary Deployment: When testing a new feature with a subset of users before a full rollout to evaluate performance and catch issues early.

3. Blue-Green Deployment: When you need to ensure a quick rollback mechanism and minimize risks during major updates.
