Monthly performance and delivery summary for drone-runners/drone-runner-aws (2025-10). Focused on improving Nomad driver initialization performance and expanding VM initialization observability to enable faster provisioning, better troubleshooting, and data-driven optimization.

May 2025 performance recap: Strengthened reliability of savings processing across core repos, implemented Go 1.19-compatible error aggregation, and updated LiteEngine integration to address savings handling issues. These efforts reduced error ambiguity, improved build stability, and enhanced cross-repo alignment for future feature work.

April 2025: Implemented generalized AWS Disk Encryption for drone-runner-aws, extending KMS-based encryption to all EBS volume types and any block device mapping when a KMS key ID is provided. This refactor aligns with CI-16881 and prepares for broader disk-type support (#573).

January 2025 performance summary: Delivered mutual TLS (mTLS) support for self-hosted VM runners across two repositories, improving security and reliability of self-hosted CI execution. Implementations include mTLS configuration in pipeline setup, client certificate management, and integration with the log streaming client. Updated dependencies and log logger to recognize mTLS settings, enhancing connectivity and security posture. No major bugs fixed in this period; the focus was on secure delivery and operational resilience. Business impact: reduced credential exposure, stronger data-in-flight protection, and more predictable, auditable runner communications.
