Deployment Strategies overview

Deployment Strategies as a meta-topic encompassing the full spectrum of release patterns — rolling updates, blue/green environment switches, canary traffic splits, feature-flag-gated dark launches, shadow deployments, and A/B experiments. Each strategy balances risk, rollback speed, infrastructure cost, and observability requirements. Acts as the organizing concept linking topic:blue-green-deployment, topic:feature-flags, workflow:canary-deployment, and related progressive-delivery patterns across the atlas graph.
