AWS would give developers a middle tier between Lambda functions and ECS or EC2. You get per-VM identity, network addressability, and stronger process isolation while keeping Lambda's burst model.
The runtime would fit workloads that need warm state, longer-lived workers, per-tenant sandboxes, protocol servers, job runners, or untrusted code execution.
Teams would judge it on startup time, VM lifetime, image format, IAM boundaries, pricing for idle microVMs, and network limits. The useful version lets you treat each microVM as a durable endpoint without taking on EC2 fleet work.
