What is this?
Microservices split an application into small, independently deployable services with bounded contexts and own data stores.
Why should you care?
CloudVerse banking ships payments without redeploying the entire monolith.

Use AWS/Azure/GCP free tier or local Docker/Kind. Sketches and YAML are meant to be typed and adapted.
# docker-compose lab (CloudVerse shop)
services:
orders-api:
image: cloudverse/orders:1.2.0
environment:
DB_HOST: orders-db
ports: ["8081:8080"]
inventory-api:
image: cloudverse/inventory:1.1.0
environment:
REDIS_URL: redis://cache:6379
ports: ["8082:8080"]
gateway:
image: cloudverse/gateway:1.0.3
ports: ["8080:8080"]
depends_on: [orders-api, inventory-api]
What happened?
- Each service owns its schema.
- APIs and async events connect them.
- Operational complexity rises — invest in platform tooling.
Practice next
- Split one feature into its own repo.
- Define REST contract.
- Deploy two services independently.
- Add async checkout via message bus.
- Introduce contract tests between services.
Remember
Small deployable units. Own data per service. APIs + events connect.
CloudVerse checkout split
Inventory team releases daily; orders weekly.
Outcome: Independent deploys reduce release risk.
