Dec 1, 2025December 2025 — ministryofjustice/modernisation-platform-environments: Delivered critical WAF fixes, Terraform infrastructure stabilization, and scheduling enhancements for Lambda deployments. Major bugs fixed reduced error surfaces and improved reliability. Business value delivered includes more predictable deployments, reduced operational risk from mis-timed tasks, and better alignment with holidays and testing scenarios. Key focus areas included WAF configuration and rule hygiene, cron/time management, and maintainability improvements through code quality work and cleanup. Key deliverables and impact: - WAF Issues Fixes: configuration, logic, and error handling improvements across multiple commits, enhancing security posture and reliability. - Terraform Apply Issue Fixes: stabilization of Terraform apply, reducing deployment failures and drift. - Timeslot/Timescale and Cron Improvements: corrected scheduling logic, updated cron timing, and enhanced test capabilities; bank holiday and out-of-office scheduling added for business continuity. - Lambda Deployment and Cron Integration: updates to lambda files and configuration to support reliable deployments and proper cron-based triggers. - Code Quality and Cleanups: apply mypy recommendations, remove unnecessary comments, unify naming, and remove duplicate Lambda custom for WAF consistency. - Cleanup and Alignment: WAF ACL repointing, rule name alignment, and related cleanup to reduce maintenance risk. - Added Assets: new file contents and testing enhancements to support feature validation. Overall impact: Increased deployment reliability, stronger security posture, and improved operational efficiency through standardized scheduling, clearer governance of WAF/Lambda integration, and maintainable code improvements.
