Ringkasan

Build, run, debug, and operate applications on AWS Lambda MicroVMs — Firecracker-isolated, snapshot-resumable serverless compute environments that run inside a container with up to 8-hour lifetimes. Triggers on: Lambda MicroVMs, Firecracker isolation, snapshot-resumable compute, suspend/resume, sandboxed or untrusted code execution, AI/agent code-execution sandboxes, interactive code playgrounds and notebooks (Jupyter, REPLs), reinforcement-learning environments, multi-tenant CI executors and build runners, sessionful game or simulation servers, isolated security scanners, long-lived sessions, or port-listening servers (gRPC, WebSocket, custom TCP). For standard event-driven Lambda functions, use the aws-lambda skill instead.

AWS Lambda MicroVMs

The AWS MCP server is recommended for sandboxed execution and audit logging.

AWS Lambda MicroVMs are serverless compute environments that combine Firecracker VM isolation with container-like efficiency. Each MicroVM:

Runs your application as a container inside a Firecracker microVM — you can reproduce the environment locally.
Runs Amazon Linux 2023 as the base OS inside the MicroVM.
Boots from a memory + disk snapshot captured at image build time, so application init is skipped on run.
Has a dedicated, TLS-terminated HTTPS endpoint reachable with an auth token.
Can be suspended and resumed with state preserved; lives up to 8 hours.

Two-resource model:

MicrovmImage — a versioned artifact built from {S3 zip with Dockerfile} + baseImageArn. Each version has per-architecture/chipset Builds.
Microvm — a running instance created (RunMicrovm) from an image version.

Two roles:

buildRoleArn — used during image build (S3 read, CloudWatch logs, optional ECR).
executionRoleArn — assumed at runtime by the running MicroVM.

When to use

Choose Lambda MicroVMs when

Analytics workloads — isolated compute for data processing, ETL jobs, or query execution with strong tenant separation.
AI / agent code execution sandboxes — fresh, isolated environment per session, fast resume between turns.
Interactive code playgrounds & notebooks — Jupyter, REPLs, dev environments executing user code.
Reinforcement-learning environments — clean per-episode envs with tool access.
Multi-tenant CI executors / build runners — strong tenant isolation.
Game / simulation servers — sessionful, long-lived (up to 8 hr) workloads.
Security scanning — running untrusted analyzers in isolation.

In general, Lambda MicroVMs are suited for long-lived sessions, real port-listening servers (gRPC, WebSocket, custom TCP protocols), state preserved across periods of inactivity (suspend/resume), container-level access (FUSE, eBPF, custom syscalls), or session-affine routing to a specific compute environment.

Choose AWS Lambda (functions) when

The workload fits in 15 minutes.
Per-invocation isolation is fine; no need for session state held in memory.
Fully automatic scaling is preferred (no RunMicrovm to manage).
Event-source integrations (S3, SQS, EventBridge, etc.) drive the function.

Choose something else when

Continuous compute beyond 8 hr → ECS / EKS / EC2.
Lift-and-shift workloads needing kernel modifications or a non-Linux OS → EC2.

Typical workflow

Check regional availability — confirm Lambda MicroVMs is available in your target region (run aws lambda-microvms list-managed-microvm-images). Your S3 artifact bucket and any network connectors must be in the same region as the image.
Package an app: zip with a Dockerfile at the root, upload to S3 (same region as the image).
Implement lifecycle hooks (optional but recommended) — HTTP endpoints on a port you specify (commonly 9000) for /run, /resume, /suspend, /terminate, /ready, /validate.
CreateMicrovmImage — pointing at the S3 artifact, a managed base image, and a build role. Lambda compiles the Dockerfile into an OCI image, starts your app, calls /ready, snapshots disk + memory, optionally validates with /validate. Lambda will periodically release new managed image versions, and customers should re-build using the latest version to ensure they have up to date images.
RunMicrovm — pick an image version, attach executionRoleArn, set idlePolicy, ingress/egress connectors, and (optionally) a runHookPayload. Receive an endpoint URL and microvmId.
CreateMicrovmAuthToken — get an auth token (max 60 min) with allowedPorts specifying which ports the token grants access to. Send traffic to the endpoint with X-aws-proxy-auth: <token>.
Suspend / Resume / Terminate — explicit APIs, or let the idlePolicy drive it (maxIdleDurationSeconds, suspendedDurationSeconds, autoResumeEnabled).

See references/getting-started.md for the full walkthrough including --hooks config and lifecycle hooks.

Hook configuration

Hooks are organized into two groups under the --hooks parameter:

`microvmImageHooks` (build-time)

Recommendation: Implement the image build hooks (/ready and /validate) for best performance. They enable the platform to capture a complete snapshot and prefetch the portions accessed at run time.

Hook	Purpose	Timeout range
`ready`	Called during application boot. When this hook returns a 200 status code, it signals to the platform that the application is ready to be snapshotted. Use this to ensure your application is fully booted before a snapshot is taken. If your application is not yet ready, return a 503 status code until it is ready for snapshotting.	1–3600s (default 30s)
`validate`	Called after running your application from the microVM snapshot. Use this hook to validate the application is ready to serve traffic. This hook additionally allows the platform to sample the portions of the snapshot that are used when your application is ran, allowing Lambda to prefetch those portions of the snapshot to reduce latency. To get the best performance, run mock payloads through the application during validate. When this hook returns a 200, it signals to the Lambda the MicroVM image is valid. If your application needs more time to run its validate workflow, return a 503 status code.	1–3600s (default 30s)

Why implement /ready? It signals the platform that your application has fully booted. Without it, the snapshot may be taken mid-initialization, meaning the cached state is incomplete and every run repeats part of the boot sequence.

Why implement /validate? It lets the platform verify the snapshot is correct, and also samples which portions of the snapshot are accessed during RunMicrovm. This allows the platform to prefetch those portions on future launches, reducing cold-start times.

`microvmHooks` (runtime)

Hook	Purpose	Timeout range
`run`	Fires once after run from snapshot	1–60s (default 1s)
`resume`	Fires after SUSPENDED → RUNNING	1–60s (default 1s)
`suspend`	Fires before RUNNING → SUSPENDED	1–60s (default 1s)
`terminate`	Fires before termination	1–60s (default 1s)

See references/getting-started.md for a full example enabling all hooks.

Per-MicroVM size limits

Resource	Limit
Maximum vCPUs per MicroVM	16
Maximum memory per MicroVM	32 GB

For all other quotas — concurrent MicroVMs per account, launch rate, image count, max execution duration, auth token TTL, Lambda Network Connector (LNC) limits, per-ENI bandwidth, etc. — check the AWS docs / Service Quotas console. Most are soft quotas, raisable through Service Quotas / Support.

Additional capabilities

By default, the container runs with a restricted set of Linux capabilities. Set --additional-os-capabilities '["ALL"]' at image creation time only when required by your use case:

Filesystem mounts — EFS, FUSE-based filesystems.
Nested containers — running additional containers with containerd inside the MicroVM.
eBPF programs — tracing, profiling, or custom network policies.

aws lambda-microvms create-microvm-image \
  --name my-image \
  --base-image-arn arn:aws:lambda:<region>:aws:microvm-image:al2023-1 \
  --build-role-arn arn:aws:iam::<acct>:role/MicroVMBuildRole \
  --code-artifact '{"uri":"s3://<bucket>/<key>.zip"}' \
  --additional-os-capabilities '["ALL"]'

Shell ingress for agent use cases

For programmatic shell access (agent workflows, remote command execution), use the SHELL_INGRESS network connector:

# AWS Lambda MicroVMs

> The AWS MCP server is recommended for sandboxed execution and audit logging.

AWS Lambda MicroVMs are serverless compute environments that combine Firecracker VM isolation with container-like efficiency. Each MicroVM:

- Runs your application as a **container inside a Firecracker microVM** — you can reproduce the environment locally.
- Runs Amazon Linux 2023 as the base OS inside the MicroVM.
- Boots from a **memory + disk snapshot** captured at image build time, so application init is skipped on run.
- Has a dedicated, TLS-terminated HTTPS endpoint reachable with an auth token.
- Can be **suspended and resumed** with state preserved; lives up to 8 hours.

**Two-resource model:**

- `MicrovmImage` — a versioned artifact built from `{S3 zip with Dockerfile} + baseImageArn`. Each version has per-architecture/chipset `Build`s.
- `Microvm` — a running instance created (`RunMicrovm`) from an image version.

**Two roles:**

- `buildRoleArn` — used during image build (S3 read, CloudWatch logs, optional ECR).
- `executionRoleArn` — assumed at runtime by the running MicroVM.

Skill purpose: Build, run, debug, and operate applications on AWS Lambda MicroVMs — Firecracker-isolated, snapshot-resumable serverless compute environments that run inside a container with up to 8-hour lifetimes. Triggers on: Lambda MicroVMs, Firecracker isolation, snapshot-resumable compute, suspend/resume, sandboxed or untrusted code execution, AI/agent code-execution sandboxes, interactive code playgrounds and notebooks (Jupyter, REPLs), reinforcement-learning environments, multi-tenant CI executors and build runners, sessionful game or simulation servers, isolated security scanners, long-lived sessions, or port-listening servers (gRPC, WebSocket, custom TCP).
