What should the system boundaries look like?
Use this hub when you are deciding between service shapes, asynchronous boundaries, state placement, or multi-account and multi-region strategy.
Topic hub
Architecture decisions, service boundaries, and production patterns for building serious systems on AWS.
Questions this hub should help answer
Use this hub when you are deciding between service shapes, asynchronous boundaries, state placement, or multi-account and multi-region strategy.
Look here for articles that go beyond “service A vs service B” and into blast radius, failure isolation, and operational cost.
If the decision is still architectural rather than implementation-level, move into the architecture library and then come back for deeper reads.

Open one article that gives the clearest view of how this problem space behaves in production, then continue into the wider set below.
Direct S3-to-Lambda triggers are simple, but burst traffic and slow downstream systems change the decision. Here is when SQS belongs in the middle.
Within this topic
These pieces stay inside the same operating surface and are better for depth once you already have the context from the spotlight read.
Design the traffic, network, database, secret, scaling, and cost boundaries for a Fargate web application instead of stopping at deployment.
