Month: 2025-09 — This month focused on strengthening reliability, observability, and startup performance for the drone-runner-aws deployment, delivering two major capabilities and laying groundwork for more predictable scaling. Key features delivered: - Hotpool observability and warm provisioning metrics: added WarmPoolCount for hot pool instance states; Provision now returns a boolean indicating if an instance was warmed up; WaitDurationCount metrics updated to include warmed-info. These changes improve capacity visibility, problem diagnosis, and proactive scaling. (Commit: eed5539a6a9d01a07b70ce5bb75578c08c5316fd) - BYOI image handling via local VM images: refactored BYOI to rely on local VM images instead of OCI pulls; introduced encoding, pulling, exporting, and importing VM image tooling to improve reliability and startup performance. (Commit: 9e7fa21232e59a031551900d53839e751ea95646) Overall impact and accomplishments: - Improved reliability and predictability of runner startup by removing external image pull dependencies and enhancing pool health visibility. - Faster incident response and capacity planning through richer metrics around warm pools and provisioning state. Technologies/skills demonstrated: - Metrics instrumentation and observability (custom metrics for hot pools and warm provisioning) - Refactoring for enhanced provisioning semantics - Local VM image lifecycle tooling (encoding, pulling, exporting, importing) for BYOI - Dependency minimization to improve startup performance and reliability
