Keynote: Open Source & AI at the Core: How Microsoft Builds and Runs on OSS

on YouTube ↗10m

" summary

Microsoft traces a shift from skepticism to heavy OSS contribution — a 2009 patch of 20,000 lines to the Linux kernel precedes Visual Studio Code (2015) and GitHub: 28M devs then vs 518M projects now. Two thirds of Azure VMs run Linux and core services use AKS/Kubernetes with KEDA, Prometheus and Grafana. ChatGPT runs on AKS for over 500 million weekly users with ~12 admins scaling to millions of cores. Open projects released include Copacetic, Dalec, Radius, Dapper, SBOM tooling, Semantic Kernel and FI.
