Cloud & Datacenter Infrastructure

We build cloud and datacenter infrastructure that remains predictable under high consolidation. Our work spans serverless and Function-as-a-Service runtimes, resource scheduling, isolation, virtualization, SLO/QoS management, and memory-aware resource management. We connect datacenter runtime decisions with the underlying architecture to improve utilization, latency, and energy efficiency.
