This pattern deploys a Lambda MicroVM from a zip artifact uploaded to S3. The zip contains a Dockerfile and application code. Lambda builds the image server-side on the al2023 base image, waits for the /ready lifecycle hook, and takes a Firecracker snapshot.

The MicroVM resumes rapidly from the snapshot, exposing an HTTP endpoint on port 8080 gated by an auth token. It automatically suspends after idle timeout and resumes on next request — each MicroVM runs in its own isolated VM with hardware-level isolation.
