Modal rebuilds sandbox infrastructure to scale 1 million concurrent sandboxes in seconds

Modal engineers rebuilt their sandbox platform to avoid centralized coordination (e.g., etcd-backed Kubernetes control planes), making each worker the source of truth and running many parallel schedulers. In benchmarks the new architecture created 1 million sandboxes in under a minute with median startup-to-code under 0.5s and sustained tens of thousands of sandbox creations per second.

Fixing the AI infra scale problem by stuffing 1M sandboxes in a single server (Unikraft presentation)

Felipe Huici presents how Unikraft uses isolation primitives, Linux kernel optimizations, and snapshotting techniques to enable millisecond cold boots, stateful scale-to-zero, and extreme density for sandboxing AI workloads. He reports being able to maintain sub-10ms performance at scale and describes integration with Kubernetes and hardware-level security.
