What problem does it solve? Setting up AWS Resilience Hub v2 for the first time involves a long sequence of interdependent API calls — creating resilience policies with SLO targets, registering systems and user journeys, onboarding services with input sources, and running failure mode assessments — where a single misconfigured parameter or missed step breaks the workflow. ## Core Features & Use Cases - Guided end-to-end setup: Walks through a 10-step procedure covering policy creation with availability/RTO/RPO targets, system and user journey registration, service onboarding with invoker IAM roles, and input source configuration (CloudFormation stacks, resource tags, Terraform state, or EKS clusters). - Failure mode assessment execution: Starts asynchronous assessments, polls for completion, and presents findings grouped by severity with infrastructure, observability, and testing recommendations. - Security and troubleshooting guidance: Enforces least-privilege invoker roles, confused-deputy condition keys, SSE-KMS encryption for Terraform state and reports, and diagnoses common issues like stuck assessments or NOT_ACHIEVABLE results. - Use Case: A platform engineer wants to onboard a tier-1 checkout service with a 99.99 availability SLO and 5-minute RTO, then run a first failure mode assessment to identify single points of failure before a launch review. ## Quick Start Set up AWS Resilience Hub v2 for my checkout-api service with a 99.99 availability target, 5-minute multi-AZ RTO, and a CloudFormation stack as the input source, then run a failure mode assessment.
