Cloud Custodian

About Cloud Custodian

Cloud Custodian is an open-source cloud governance tool that enables organizations to define policies to manage and enforce compliance across cloud resources. It operates across multiple public cloud environments and supports early enforcement of security, cost optimization, and governance policies through a YAML DSL. The project emphasizes real-time remediation, policy-as-code workflows, and unified metrics and reporting, with active community involvement including Slack channels and a GitHub repository. It is open source, CNCF-incubating, and focuses on governance and cost management for AWS, Azure, and GCP, with beta support for Kubernetes, Tencent Cloud, and OpenStack.
