Deployment Strategies

1. Rolling Deployment (Default)

  • Use Case: Minor updates, patches
  • Process: Gradual pod replacement, zero downtime
  • Rollback: Automatic on health check failure
  • Resources: No additional resources required

2. Blue-Green Deployment

  • Use Case: Major version updates
  • Process: Deploy to inactive environment, switch traffic instantly
  • Rollback: Instant traffic switch back
  • Resources: Requires 2x resources temporarily

3. Canary Deployment

  • Use Case: High-risk changes
  • Process: Progressive traffic shift (10% → 50% → 100%)
  • Rollback: At any phase
  • Resources: 1 additional replica initially
