This 30-minute talk explores how we transformed the open-source Spring Authorization Server into an enterprise-grade Security Token Service (STS) capable of supporting millions of users. I’ll share our practical journey from evaluation to production deployment, with a focus on the architectural decisions, customizations, and performance optimizations that made this possible. You’ll learn how we identified and addressed performance bottlenecks, integrated with complex enterprise systems, and maintained security compliance while scaling horizontally. This case study demonstrates how open-source software can be extended to meet even the most demanding enterprise requirements without forking the codebase, allowing organizations to benefit from both community innovation and enterprise reliability.
