A Service Component is a software component that provides functionality to other system components through defined service interfaces.
- Context:
- It can typically expose Service Operations through service APIs.
- It can typically process Service Requests from service consumers.
- It can typically return Service Responses to calling components.
- It can typically implement Business Logic through service implementation.
- It can typically maintain Service Availability through reliability mechanisms.
- ...
- It can often manage Service State through state persistence mechanisms.
- It can often ensure Service Security through authentication mechanisms and authorization controls.
- It can often provide Service Discovery through registration mechanisms.
- It can often handle Service Failure through error handling strategy.
- It can often monitor Service Performance through metrics collection.
- ...
- It can range from being a Simple Service Component to being a Complex Service Component, depending on its service component functional complexity.
- It can range from being a Stateless Service Component to being a Stateful Service Component, depending on its service component state management approach.
- It can range from being a Synchronous Service Component to being an Asynchronous Service Component, depending on its service component interaction pattern.
- It can range from being a Monolithic Service Component to being a Microservice Component, depending on its service component architectural granularity.
- ...
- It can integrate with Service Registry for service discovery.
- It can connect to Data Storage System for data persistence.
- It can utilize Monitoring System for service health tracking.
- It can support Load Balancer for request distribution.
- ...
- Examples:
- Service Component Types, such as:
- Business Service Components, such as:
- Infrastructure Service Components, such as:
- Integration Service Components, such as:
- Service Component Architecture Patterns, such as:
- RESTful Service Component implementing REST architectural style.
- SOAP Service Component implementing SOAP protocol standard.
- GraphQL Service Component implementing GraphQL query language.
- ...
- Service Component Types, such as:
- Counter-Examples:
- Library Component, which provides functionality through code import rather than service interfaces.
- UI Component, which interacts with users rather than other system components.
- Data Component, which primarily manages data structures rather than providing service functionality.
