January 2026 (2026-01) delivered caching optimizations and governance updates for ministryofjustice/cloud-platform-environments. Implemented Elasticache Redis caching across development and production environments with per-environment and per-application configurations (notably laa-submit-a-bulk-claim), including Redis cluster provisioning, Kubernetes secrets, and Terraform modules. Also removed obsolete Elasticache configuration in UAT/Staging/Prod where applicable to reduce drift. Terraform updates updated the default development team name across all environments to reflect new ownership, improving clarity of responsibility and deployment governance.
