AWS, serverless, and cloud infrastructure

Where Should Claude Code Run? Devcontainer, Codespaces, or MicroVM

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.

Choosing a Serverless Internal Service Layer7/7

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.

awsaws-cdklambda+4
gRPC, Protobuf, and the Wire Format Your Gateway Allows6/7

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.

awsaws-cdklambda+4
Building the Layer with a Private API Gateway5/7

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.

Identity and Encryption Between Serverless Services4/7

SigV4 proves which service is calling and nothing about which user it is for. How to propagate a verified subject, and what the transport actually encrypts.

Multi-Account: Cross-Account Calls and the Data Perimeter3/7

Same-account, the resource policy and the caller's identity policy are an OR. Cross-account they become an AND, and silence denies. What that changes in the perimeter.

awsaws-cdklambda+4
How the Layer Fails: Throttles, Retries, and Loops2/7

API Gateway shares one throttle bucket with your front door, never retries a Lambda integration, and cannot see loops through itself. What you have to rebuild.

awsaws-cdklambda+4
Observability, and Where Service Meshes Are Heading1/7

The access log already names the caller, route, and latency. Per-route metrics are not free, the user token needs masking, and AWS is switching off its own mesh.

Should Stateful Resources Live in a Separate CDK Stack?

A lifecycle test for CDK stack layout: give a resource its own long-lived stack when it outlives any single deployer, then reach it by a well-known name.
