Deployments
Everything at the same time
✅ good for vendor-packaged solutions like desktop applications ✅ good for non-production systems (e.g., re-creating a development environment) ❌ bad for modern applications since risks are unacceptable
✅ good since no downtime ✅ sometimes coexistence is difficult / not compatible ✅ Good for distributed systems, suitable for containers
Fail-safe process
✅ Rollback easy
❌ Relies on traffic routing, DNS CNAMES can takes long due to long TTL ❌ Requires 2 identical environment
Like blue-green, deploys to small group of users:
- Geographic area
- IP address
- Internal / External users
- For defined user groups
❌ + Risky
