Microservices

Microservices structure systems as small, loosely coupled services with own data stores and deployment lifecycles, communicating via lightweight protocols. Benefits include scalability and team autonomy; costs include operational complexity and distributed data challenges. Microservices suit certain domains—not every system benefits from decomposition.

In Practice

Larkinized LLC evaluates fit-for-purpose before mandating microservices—sometimes modular monoliths reduce premature complexity. Standards cover service templates, observability, and API contracts in the pattern library. Strangler migrations gradually extract services from monoliths with architecture oversight.

Example

Order pricing becomes an independent microservice with its own datastore behind a versioned REST API and centralized logging.
