SOA_010：ESB 交互模式总结 （摘录+整理）

1. Simple synchronous request/reply flow


2. Non-deterministic synchronous request/reply flow
   • Consumer does not explicitly know the service provider
   • Service provider selection based on message content/header




3. Simple 1-way asynchronous flow
   • The simplest but also the most typical ESB pattern
   • “Fire-and-forget”


4. Fan-out 1-way asynchronous flow
   • 1 event triggers multiple parallel operations
   • All outbound operations can be grouped in one or more transactions



5. Response-forwarding


6. Canonical Data Model
   
   • All messages on the bus are converted to a common data model
   • Reduces the overall number of maps to generate
   • Respective application owners only need to know about 2 data models: their own one + the canonical one.
