Cloud Custodian vs emma Governance

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.

emma Governance embeds policy controls and audit trails into cloud, Kubernetes and on-premises operations. A project can specify permitted clouds, regions and environments, then attach policies, budgets and security rules. Checks can run during interface provisioning, API calls, infrastructure-as-code work and CI/CD, with non-compliant deployments blocked. The governance model spans cloud accounts, Kubernetes clusters and namespaces, private clouds and on-premises systems. Projects can restrict residency to selected countries, regions or providers, with requirements enforced during deployment. Roles include operator, owner and auditor, and high-risk actions can be reserved for chosen people or groups. Logs capture who made a deployment or change, where and when; evidence can be exported by project, business unit or jurisdiction. Listed integrations include API, Terraform, Backstage, Jenkins and GitLab.
