*The infrastructure of a SOA landscape that enables the interoperability of services.<br />
*Its core task is to provide connectivity, data transformations, and (intelligent) routing so that systems can communicate via services.<br />
*ESB is just a piece of software, hardware is not part of ESB.<br />
<br />
<br />
==ESB Responsibilities==<br />
*Providing connectivity<br />
*Data transformation<br />
*(Intelligent) routing<br />
*Dealing with security<br />
*Dealing with reliability<br />
*Service management<br />
*Monitoring and logging<br />
<br />
<br />
==Interoperability through transformation==<br />
*May transfer any protocol to any protocol<br />
*May change the formats or mappings<br />
*May contain transformation logic<br />
*Should not contain business logic<br />
<br />
<br />
==Routing==<br />
*There must be some way of sending a service call from a consumer to a provider, and then sending an answer back from the provider to the consumer<br />
*Depending on the technology used, and the level of '''intelligence''' provided, this task may be trivial, or may require very complicated processing<br />

<br />
==Other Important Concepts==<br />
*Point-to-Point Connections Versus Mediation<br />
*Data Mapping<br />
*Security<br />
*Reliability (message delivery and queueing)<br />
*Service Management (replaces UDDI)<br />
*Monitoring and Logging<br />
<br />
<br />
==Business Activity Monitoring (BAM)==<br />
*Shows the state of your business on the fly<br />
*Analyses activity rather than data (compare data warehouse and data mining)</div>Izabela Szlachta
