Production deployment is a risk-management problem: delivering change while controlling blast radius, downtime, and rollback complexity. This paper consolidates five deployment strategies - Big Bang, Rolling, Blue-Green, Canary, and Feature Toggles and adds an operational layer as an original contribution: (i) a Deployment Risk Index (DRI) to select a rollout pattern; (ii) a Compatibility Envelope (CE) model to reason about multi-version coexistence in stateful systems; and (iii) Release Readiness Gates (RRGs) that operationalize canary evaluation and automatic pause/rollback. The guidance is aligned with established SRE and cloud-provider recommendations.
