Keynote: The Big Leap: Conquering the Legacy System and Building a Scalable Cloud...
summary
Built a custom Kubernetes-based platform "Elastic Cloud" that runs 50,000 pods on 3,000+ servers and replaces mixed physical/container deployments. Solved scheduling, isolation, and containerization by adding local storage, startup optimizations, CPU/network/disk isolation and a custom scheduler; this lifts density and stability — density 25% → 40% CPU and CPU stddev 14 → 10, while lowering tail startup/wait times and reducing a contention CPI metric from ~0.88 to ~0.45. Ongoing work: hybrid native-container support, tighter orchestration, and isolation improvements.
