🎯 Quick Start¶
Choose Your Strategy¶
Need zero downtime? → Use Rolling Update, Blue-Green, or Canary
Need instant rollback? → Use Blue-Green deployment
Limited resources? → Use Rolling Update or Recreate
High-risk deployment? → Use Canary or Blue-Green
Testing with real users? → Use Canary or A/B Testing
📖 Strategy Overview¶
1. Recreate 🔁¶
- Downtime: Yes
- Complexity: Low
- Use Case: Dev/staging environments
2. Rolling Update 🔄¶
- Downtime: No
- Complexity: Low
- Use Case: Most production apps (default)
3. Blue-Green 🟦🟩¶
- Downtime: No
- Complexity: Medium
- Use Case: Critical apps needing instant rollback
4. Canary 🐤¶
- Downtime: No
- Complexity: High
- Use Case: High-risk features, gradual rollout
5. A/B Testing 🅰️🅱️¶
- Downtime: No
- Complexity: High
- Use Case: Feature comparison, optimization
