Sep 1, 2025Monthly summary for 2025-09: In awslabs/landing-zone-accelerator-on-aws, delivered key features, fixed critical issues, and improved cost efficiency and reliability. Major outcomes include: 1) AWS CodeBuild Pipeline Partition Environment Variable: added partition env var to pipeline config to ensure region-specific validation uses the correct partition; snapshot tests updated. 2) AWS Control Tower Access Logs Retention Reduction: lowered default retention from 3650 days to 365 days across multiple config files, achieving storage cost savings with balanced retention. 3) Validation stability: reverted the fix that enforced Route53 resolver endpoints to be configured when query logs are present; removed the validation check and its test file to avoid regressions. Overall impact: improved deployment correctness, reduced operational costs, and easier maintenance. Technologies/skills: CI/CD (CodeBuild), AWS services (CodeBuild, Route53, Control Tower), configuration management, test-driven updates, regression handling.
