ESB (iii) Integration of Web service services across platforms and heterogeneous systems

Four modes of 1.mule ESB Integration SystemA. Simple service Mode

a synchronous call that belongs to several Web service, request response processing mode. B. Bridging mode


C. Checker mode

the validator mode filters the service request by defining a checksum filter and synchronously returns the ACK (acknowledge) or nack (not acknowledge) result. Service requests that are verified are distributed asynchronously to the processor.
D. Service agent model

in the integration we use the D mode, in the middle of a proxy to transit request processing, the address of the external release is flexible, when the provider's Web service changes, there is no need to change the service user's code, equivalent to the role of decoupling.

Where the The Mule ESB is a message framework for data interaction between applications, and various applications are encapsulated by the ESB in order to serve transport to enable the data between services to interact, and the data is converted into data formats during transport transfer. The Mule ESB solves the interaction problems among various systems, platforms, and complex systems, and supports a variety of transport protocols, such as JMS, FTP, JSON, XML, RMI, in addition to Web service support. the next one is about to invoke the JMS messaging service through the ESB so that each system can communicate asynchronously.
