Domain Driven Service Decomposition

Use When

• Service boundaries are unclear or causing coupling
• Teams are planning monolith-to-microservice migration

Workflow

1. Identify domains, subdomains, and bounded contexts.
2. Map business capabilities to ownership-aligned services.
3. Define context boundaries, contracts, and data ownership.
4. Validate boundaries against team cognitive load and release autonomy.
5. Plan incremental extraction slices with anti-corruption layers.
