Modal on Scaling to One Million Concurrent Sandboxes
dejavucoder · x · 2026-07-17
Modal details how they scaled agent sandboxes to 1 million concurrent instances, emphasizing that this foundational capability is what allows agents to truly "act within software."
Key takeaways include:
- Agent execution requires isolated, fast-starting sandbox environments.
- Their system is designed to scale these environments in seconds and handle massive concurrency.
- This type of infrastructure directly dictates whether agents can be deployed at scale.
The article also suggests that as agents evolve into a "software workforce," the runtimes and sandbox layers supporting them will become critical infrastructure.
