What is this?
A blueprint stitches gateway, services, data ownership, async messaging, observability, and SLOs into one reference architecture.
Why should you care?
ShopNest teams need a shared picture so every new service does not invent a conflicting style.
See it live — copy this example
Sketch the architecture on paper. These lessons focus on concepts and trade-offs.
Edge: CDN + Gateway + WAF
Services: domain microservices on K8s
Data: DB per service + Redis + blob
Async: Kafka for domain events; Rabbit for jobs
Obs: logs/metrics/traces + SLOs on checkoutRun Example »
This lesson uses terminal or setup steps. Run commands on your computer — the live editor appears on coding lessons.
What happened?
- The blueprint is a living standard: approved tools and patterns.
- Exceptions need review.
- It speeds onboarding and incident response.
Practice next
- Draw the ShopNest blueprint one-pager.
- List approved stores and buses.
- Define checkout SLO.
- Add a fraud service using only approved event bus.
- Review exceptions quarterly.
Remember
One reference architecture. Approved building blocks. SLOs on critical journeys.

New services copy the blueprint.
Outcome: Fewer snowflake deployments and faster reviews.
