ESB - What?

• Enterprise Service Bus (ESB)

• An enterprise service bus (ESB) is a software architecture for middleware

that provides fundamental services for more complex architectures.

• An ESB acts as a shared messaging layer for connecting applications

and other services throughout an enterprise computing infrastructure.

• It supplements its core asynchronous messaging backbone with

intelligent transformation and routing to ensure messages are passed

reliably.

ESB - Why?

• Why ESB?

• Service Mediation

• Transformations

• Routing

• Validations

• Event Management

• Interactions

• QoS – Security, Reliability, Throttling

• Service Hosting
