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.
