March 2025 focused on reliability, efficiency, and observability across the UC-CDIS manifest work. Key features delivered include a configurable Maintenance Mode for the VADC system, enabling controlled maintenance windows and predictable request handling, and Resource Optimization to downscale components in va.data-commons.org, reducing resource usage and potential costs. A critical bug fix addressed Prometheus metrics aggregation in the aggmds component for data-commons.org, improving accuracy of monitoring data. Overall impact includes improved system reliability during maintenance, lower operating costs through resource optimization, and enhanced visibility for capacity planning and incident response. Technologies and skills demonstrated include configuration-driven feature flags, infrastructure optimization, metrics instrumentation and aggregation, and cross-team collaboration to improve observability and performance across data-commons and manifest services.
