blue_green_deployment mitigates cold_start

Source: Pattern·Target: Failure Mode

Summary

Blue-green deployment pre-warms the new environment (connections, caches, JIT) before traffic shifts, eliminating cold-start latency that would otherwise occur during in-place deployments.

Evidence

·cold_start_latency triggers include traffic routed to a new pod before warm-up and deploys with no readiness gate (failure_modes/cold_start_latency.yaml)
·blue_green shifts traffic only after green is validated with no production traffic, giving a window to warm/gate on readiness probes (patterns/blue_green_deployment.yaml)

Evidence grounding

Grounded, 2 supporting items

Blue-green supplies the pre-shift warm-up window and readiness gate; it mitigates (not eliminates) cold start only if warm-up is performed in that window.
