Servicelogik

Servicelogik is a term used in software engineering to describe the part of a system that implements the behavior and rules of a service in service-oriented and microservice architectures. It encapsulates the business logic activated when a service receives a request and coordinates interactions with domain models, repositories, external services, and messaging infrastructure. Servicelogik sits between the API contract and the data layer, and is distinct from data access concerns and the raw representation of domain entities.

Typical responsibilities include orchestrating multi-step processes, enforcing business rules, validating input, handling errors, and coordinating calls to other services or components. In distributed systems, the service logic must address consistency and fault tolerance, employing patterns such as sagas, compensating actions, idempotent operations, and retry policies. It also encompasses concerns like logging, observability, security enforcement, and transaction boundaries across service boundaries.

In practice, servicelogik is often implemented as part of an application service layer within a layered architecture, or as a dedicated microservice responsible for a specific business capability. It interacts with the domain layer to apply business rules and with infrastructure components for persistence, messaging, and external integrations. Clear boundaries between service logic, domain logic, and data access help maintain modularity and testability.
