Software Application Layer
A Software Application Layer is a software architecture layer that coordinates system components (to support request processing through service coordination).
- Context:
- It can typically process Service Requests through request handlers.
- It can typically route System Messages through message brokers.
- It can typically coordinate Service Interactions through service orchestrators.
- It can typically manage Request Flow through pipeline processors.
- It can typically handle Service Responses through response formatters.
- ...
- It can often implement Service Discovery through registry systems.
- It can often provide Load Balancing through distribution systems.
- It can often manage Circuit Breaking through failure handlers.
- It can often support Request Caching through cache systems.
- ...
- It can range from being a Simple Gateway to being a Complex Integration Hub, depending on its integration complexity.
- It can range from being a Synchronous Processor to being an Asynchronous Processor, depending on its processing model.
- It can range from being a Monolithic Coordinator to being a Distributed Coordinator, depending on its architecture pattern.
- ...
- It can integrate with Business Layer for logic processing.
- It can connect to External Service for third-party integration.
- It can utilize API Framework for service development.
- ...
- Examples:
- API Gateways, such as:
- Service Coordinators, such as:
- Message Brokers, such as:
- ...
- Counter-Examples:
- User Interface, which handles display logic rather than service coordination.
- Database Layer, which manages data persistence rather than request processing.
- Network Protocol, which defines communication standards rather than service integration.
