What is an agentic service? Consider it as a microservice.

An agentic service is a specialized microservice that encapsulates autonomous, goal‑driven behavior. Unlike traditional services that expose a set of APIs for clients to invoke, an agentic service internally decides when and how to act based on its objectives, policies, and environmental inputs. It typically includes a decision engine, a state store, and a set of actuators. For example, a recommendation agent might continuously monitor user interactions, update its model, and push personalized suggestions without explicit requests from the front‑end. Key characteristics include: 1) Autonomy – it can initiate actions; 2) Goal‑orientation – it pursues defined objectives; 3) Adaptivity – it learns or reacts to changing conditions; and 4) Interoperability – it exposes a lightweight API for status checks or manual overrides. In a microservices architecture, an agentic service can be deployed independently, scaled horizontally, and monitored separately, allowing teams to iterate on its logic without impacting other services. This pattern is useful for real‑time decision making, automation, and AI‑driven workflows.
