1. Immutable Infrastructure by Design
Configuration drift between staging and production is the leading cause of failed enterprise releases. By enforcing 100% Terraform definitions for compute, networking, and security policies, environments become completely disposable and reproducible.
2. Blue-Green & Canary Deployment Topology
Deployments must never mutate live servers in place. A new target cluster (Green) is fully provisioned, passes synthetic health checks, and receives a gradual percentage of production traffic before the old cluster (Blue) is gracefully drained and terminated.
