In their own words
Cloud Custodian
Cloud Custodian manages cloud resources through policies written in YAML. Each policy names a resource type, filters for selecting resources, and actions to apply to matches. It supports security policy enforcement, compliance, tag policies, cleanup of unused resources, and cost management for AWS, Azure, and Google Cloud Platform resources. Policies can respond to provider events through serverless features or run on a cron schedule. Users can validate policies and preview matching resources in dry-run mode before actions execute. Runs can produce policy metrics, structured resource records, and logs for cloud metrics, storage, and logging services. Documented event connections include AWS CloudWatch Events and Config Rules, Azure EventGrid, and GCP AuditLog and Pub/Sub. Installation is documented for Linux, macOS, and Windows, with Docker and Kubernetes operation also described. Kubernetes, Tencent Cloud, and OpenStack support are in beta; Terraform integration is in alpha. Cloud Custodian is free at free and open source under Apache 2.0. An AWS constraint is that event-triggered policies run only in the same region and account, while periodic policies may run elsewhere.
