silver-blast-radius

A blast radius assessment identifies the scope of proposed infrastructure changes by mapping affected resources, dependencies, and failure modes across environments to prevent uncontrolled risk. It enables safe change planning through structured risk evaluation.

To assess the blast radius of a Kubernetes cluster upgrade, map the scope of affected resources, classify downstream dependency coupling as hard or soft, and document failure scenarios, rollback steps, and change-window timing risks.

Map infrastructure dependencies by enumerating all affected resources across environments and identifying associated IaC artifacts, CI/CD definitions, and secret changes. Classify downstream dependents by coupling type to communicate risk before execution.

Yes, the blast radius assessment produces gating outputs, rollback plans, and change-window assessments specifically designed to satisfy the structured requirements for devops-quality-gates before proceeding with infrastructure changes.

The best way to plan a rollback is to perform a blast radius assessment that documents failure scenarios and validates rollback viability before execution. This produces a structured rollback plan detailing steps and change-window timing risks.

Yes, this risk assessment applies to DevOps and IaC changes across multiple environments. It details the scope of affected resources, classifies dependency coupling, and evaluates failure modes and window risks for each environment.
