Episode 134 — Upgrade Methods — Blue-Green, Canary, and Active-Passive

This episode explores upgrade deployment strategies that reduce risk and downtime. Blue-green deployments run two identical environments, switching traffic to the updated one once validated. Canary releases roll out updates to a small subset of users first, monitoring for issues before full deployment. Active-passive upgrades involve switching from a live system to a standby system for updates, then reversing the process.

We also discuss choosing the right strategy based on workload criticality, testing requirements, and rollback needs. On the Cloud+ exam, you’ll be expected to match upgrade methods to scenarios for both safety and efficiency.
