AWS Launches Lambda MicroVMs for Isolated Agent and User Code Execution
AWS just shipped the infrastructure layer for stateful AI agents. Lambda MicroVMs isolate each agent session in hardware, solving the persistence problem that's been blocking production deployments.

Why it matters
AWS is making it easier for enterprises to run isolated AI agents at scale with hardware-level security and state preservation—a critical unlock for building multi-step autonomous workflows without container overhead.
The key facts
5 to knowLambda MicroVMs: Firecracker VMs with hardware-level isolation per user/agent session
State preservation: Up to 8 hours of session state retention
Snapshot-based launch: Rapid cold-start times vs. traditional containers
Pricing comparison: $3.03/day minimum (roughly 9x Fargate spot pricing)
Use case: Isolated execution for AI agents and multi-turn user sessions
