May 2025 monthly summary focusing on key accomplishments, business value, and technical achievements for ministryofjustice/cloud-platform-environments. Primary work this month centered on cost optimization and security hardening through the decommissioning of the HMPPS Users API environments (dev, preprod, prod). End-to-end removal of Kubernetes namespaces, RBAC configurations, quotas, network policies, TLS certificates, and Terraform resources for the hmpps-users environment reduced running costs and the security risk surface. The decommissioning aligns with platform governance and simplifies future lifecycle management of environments.
