What happened
AWS added AWS PrivateLink support to Lambda MicroVMs, the Firecracker-based compute service it introduced earlier in 2026 for running isolated, stateful workloads such as AI agent sandboxes. The addition lets teams create VPC endpoints that connect directly to Lambda MicroVMs APIs and HTTP endpoints without traffic leaving AWS's private network, using the same Firecracker microVM technology that already underpins trillions of monthly Lambda invocations. The feature is available through the console, CLI, CloudFormation, and SDKs in every region where Lambda MicroVMs runs.
Why it matters for your business
Before this, connecting to Lambda MicroVMs meant routing over the public internet even for internal traffic, a nonstarter for financial services, healthcare, or government customers under network isolation requirements. PrivateLink closes that gap, which matters directly for any organization pursuing CMMC or similar compliance frameworks that require demonstrable network segmentation for workloads touching regulated data.
What to watch next
Expect AWS to extend PrivateLink support to more of its newer AI-agent-adjacent services as adoption grows in regulated sectors; teams already running MicroVMs workloads should plan the VPC endpoint migration now rather than retrofitting it once an audit asks for it.
