Programming in the Large
- Composition
- Process Models
Processes define the integration (control and data flow) of reusable components assembled by domain experts (non-programmers)
Programming in the Small
- Components
- RESTful Web APIs
Component implement discrete fine-grained functions and tasks (interfaces) developed by IT experts (programmers)
Process-driven Composition
With a process, every instruction:
- Can dynamically select, bind and execute a different service/resource
- Can timeout and be aborted if it doesn't complete within a deadline
- Is logged persistently so that its execution state can be recovered and monitored
- Can be suspended, resumed, canceled or retried by the user
- Can be part of a distributed atomic transaction
