Devcontainers, Codespaces and AWS Lambda MicroVMs as homes for a coding agent: what each rung adds, what it costs, and when moving the agent off the laptop pays off.

Before building an internal service layer, decide whether to. What the layer costs per call, the volume where VPC Lattice wins, and when direct invoke still beats it.

A private REST API structurally cannot carry gRPC, and every AWS surface that speaks gRPC excludes Lambda targets. What to keep from gRPC, and what to drop.

The private REST API, the resource policy that switches it on, per-route AWS_IAM grants, the two CDK stacks, and signing the call from a Node 22 Lambda.
