Enterprise Service Bus (ESB)

An enterprise service bus (ESB) is a software architecture model used for designing and implementing the interaction and communication between mutually interacting software applications in Service Oriented Architecture

JMS and SOAP
routing messages from one point to another.there's a single point for incoming messages which are sent to
different destinations without revealing the sender's identity

ESB is a software architecture which provides fundamental services for complex architectures via
event-driven and standards-based messaging-engine(bus)

Benefits
Divergence(branching off)integration methods:
standardization of API
enterprise application integration(EAI) frameworks/practices
re-usable interfaces
Reduces cost and cost of change:
loosely coupled architecture
change/support
management/monitoring




  • WebSphere Enterprise Service Bus
IBM WebSphere Enterprise Service Bus ,for quick integration of applications and processes

  • Microsoft BizTalk ESB
An Enterprise Service Bus (ESB) is an architectural pattern and a key enabler in implementing the infrastructure for a service-oriented architecture (SOA)

  • WebSphere Message Broker
IBM WebSphere Message Broker provides an Enterprise Service Bus (ESB) that has been designed for universal connectivity and transformation in heterogeneous IT environments.

  • BEA AquaLogic Service Bus

BEA AquaLogic Service Bus is an intermediary for use as a core element of distributed services networks. It enables service-oriented architecture (SOA) allowing accelerated service re-use and deployment.

  • Oracle Service Bus 

Oracle Service Bus transforms complex and brittle architectures into agile integration networks by connecting, mediating, and managing interactions between services and applications.

  • Open Source ESB Projects

  • JBoss ESB
leverages JEMS technologies like the JBoss business rules engine for content-based routing and messaging.

  • JBoss Fuse is an open source integration platform based on Apache ServiceMix. It is a service-oriented architecture (SOA) infrastructure that provides a standardized methodology, server, and tools to integrate application components

  • Red Hat JBoss Fuse
Open source enterprise bus
flexible, small-footprint enterprise service bus (ESB) that enables rapid integration across the extended enterprise—on premise or in the cloud.

  • Apache ServiceMix
uses a JBI standard which provides a lot of components like JMS, BPEL, Web service, and Camel

  • OpenESB
solid integration with the GlassFish Application Server and Sun's popular IDE, NetBeans
OpenESB's tools include WSDL and schema editors, a JPI manager integrated into the service manager, and Ant running in the background.

  • MuleESB
Java centric

  • Petals ESB, the distributed Open-Source Enterprise Service Bus
Petals ESB is an open-source Enterprise Service Bus (ESB) provided by the OW2 Middleware Consortium. More concretely, Petals ESB is a Java platform based on SOA principles to interconnect heterogeneous systems, applications and services
