Summary
eve/sandbox/aws-lambdabackend for AWS Lambda MicroVMsWhy
AWS Lambda MicroVMs provide isolated sandboxes with lifecycle control, native suspend/resume, and authenticated HTTP ingress. This makes them suitable as an explicit eve sandbox backend when durable full-filesystem state is retained outside the eight-hour MicroVM lifetime.
Impact
The backend is opt-in and does not change default backend selection. Users provide existing IAM roles, a same-region S3 bucket, and optional network connectors. Runtime network policy remains immutable after launch.
