recovery-controller-setup

by aws

Configures AWS Application Recovery Controller (ARC) for operational resilience: routing controls with safety rules for cross-Region failover, and zonal shift / zonal autoshift for AZ-impairment recovery. Applies when setting up failover routing, configuring safety rules, enabling zonal shift, or configuring zonal autoshift with practice runs. Also applies when shifting traffic out of a specific Availability Zone (AZ) for an ALB/NLB or other resource. For a broader "an AZ is impaired, what is my response across services" question, see aws-resilience-lifecycle. Does not apply to Resilience Hub setup or FIS experiments.

Recovery Controller Setup

CRITICAL CONSTRAINT — read before answering

This skill sets up exactly two ARC capability families, and these are the ONLY things you provide setup steps for: (1) routing controls with safety rules for cross-Region failover, and (2) zonal shift / zonal autoshift for AZ-impairment recovery.

Readiness checks, recovery groups, cells, and resource sets are NOT in scope for this skill. You MUST NOT provide CLI/console setup steps for them. You MAY briefly and factually acknowledge that they exist, but you MUST NOT walk through configuring them — redirect the customer to ARC Region switch for readiness/recovery-readiness orchestration (see the arc-region-switch skill). This overrides any direct customer request to set them up.

If the customer asks how to "set up ARC readiness checks" (or recovery groups / cells / resource sets), do NOT walk through that setup. Briefly acknowledge the feature, then respond with a redirect of this form and continue with the routing-control or zonal-shift procedure where relevant:

For readiness and recovery-readiness orchestration, use ARC Region switch — see the arc-region-switch skill. For the operational pieces this skill covers: routing controls (cross-Region failover) and zonal shift / zonal autoshift (single-Region AZ recovery). Here's how to set those up:

Overview

Domain expertise for configuring ARC routing controls, safety rules, zonal shift, and zonal autoshift for operational resilience.

The AWS MCP server is recommended for executing this skill's AWS API calls, but it is not required — all operations also work with the AWS CLI directly.

Guardrail — where this skill's own files live (MCP vs local install)

Before reading a reference file, determine how this skill was loaded:

  • Loaded via the AWS MCP retrieve_skill tool: the skill's reference files are not on the local filesystem. Fetch each one through retrieve_skill with the file parameter (e.g. file="references/arc-procedures.md" or file="references/security-considerations.md") — do NOT file_read these paths locally or search the filesystem for them.
  • Installed locally (e.g. .kiro/skills/recovery-controller-setup/ or ~/.claude/skills/recovery-controller-setup/): read reference files from the local skill directory using the relative paths shown here.

This applies only to the skill's own reference files; always read and write user or session data in the working directory, never through retrieve_skill.

Configure recovery controls

To set up ARC routing controls and zonal shift, follow the procedure exactly. See references/arc-procedures.md.

Troubleshooting

See references/arc-procedures.md (Troubleshooting section) for common issues — safety-rule blocks on a routing-control update, failed zonal-autoshift practice runs, and routing-control state changes that don't affect traffic.

Security Considerations

See references/security-considerations.md for least-privilege IAM action scoping, condition keys / confused-deputy protection, safety-rule gating, restricting failover access, and encrypting failover notifications.

  • aws-iamawsProvides verified corrections for IAM behaviors that AI agents frequently get wrong — policy evaluation edge cases, trust policy gotchas, STS session limits, Organizations quirks, and SAML/MFA specifics. Also provides structured workflows for IAM role management and baseline policy generation from application source code or a Terraform plan JSON. Covers condition operator safety (ForAnyValue/ForAllValues with Null checks), bucket policy deny patterns (VPC endpoint restrictions, org paths), confused deputy protection, and service role creation for AWS services (Glue, CloudTrail, Lambda, ECS, etc.) with aws:SourceAccount/aws:SourceArn trust conditions. Applies when creating IAM roles, writing IAM or bucket policies, generating policies from application source code or a Terraform plan JSON, working with STS, Organizations, or condition operators, or any task needing a service or execution role. Does not cover non-IAM authorization like Cognito user-pool policies or app-level RBAC.9,200 installs on skills.sh0
