The request

Then tryAdd an inventory service connected to the product catalog service.Add a shipping service that consumes events from Kafka.
What is in this drawing
Read the decisions behind it.
01
API gateway is the single entry point handling auth token validation and rate limiting.
02Order to Kafka to Notification is async
slow email delivery does not block order confirmation.
03
Database-per-service prevents schema coupling; each service can choose the most appropriate DB type.
Add a service mesh block between gateway and services for observability; add Redis cache between catalog service and its DB for read-heavy product pages.
