Replacing NATS With W7S Components

ยท 11 min read

NATS is a strong general-purpose messaging system. It gives teams subjects, request/reply, publish/subscribe, queue groups, persistence through JetStream, and a fast broker that can sit between many services.

W7S does not need to copy that model to support the same application patterns. In many W7S apps, adding NATS would introduce another control plane, another credential model, another operational surface, and another local development story. The better default is to ask a narrower question:

Can the same product behavior be built from W7S components we already have?

For many cases, the answer is yes.
