Cyberinfrastructure work enabling 6× scaling of 3D biostructure data delivery across 5B requests/yr and 14.5M users. Describes the architectural changes — backwards-compatible API extensions, Elasticsearch restructuring — that made simultaneous delivery of 200K PDB structures and 1M computed models possible.

End-to-end distributed tracing across heterogeneous SCADA frameworks: how to apply APM primitives designed for web services to particle accelerator control systems. Covers reactive design principles, async event propagation, and the real-time observability gaps that traditional logging cannot close.

72-scenario load study of SciCat's metadata API across four dataset sizes, two metadata densities, and three RPS targets. Core finding: without caching the application does not scale to facility load. Informs deployment strategy for 20+ European and US research facilities.
