ESB – Introduction• ESB – Enterprise Service Bus
− IIB, Mule ESB, MS BizTalk, Oracle ESB, OpenESB, SAP PI, Talend, Apache Camel
− An ESB acts as a message broker between Service Consumers and Service Providers.
− The ESB can perform message transformations, mapping, routing and connection to applications via a variety of communication protocols.
− Its primary use is in enterprise application integration (EAI) of heterogeneous, disparate and complex systems.
− Its main architectural / integration principles: loose coupling, interoperability, endpoint and protocols abstraction, flexibility, agility, location and identity virtualization, easier interfacing, reduced costs, simplicity

ESB – Introduction• An ESB middleware:
− Identifies messages and routes them among applications and services− Enables messages to flow across different transport protocols as they move
from service requestor to service provider and back again− Transforms message formats between requestor and service− Recognizes and distributes business events to and from different sources− Provides robust and secure communications− Creates an extensible architecture based on pluggable components− Provides intelligent routing and location-independent processing− Manages descriptions and definitions of messages and their formats through
metadata− Integrates all types of assets to match the needs of your enterprise

ESB – Introduction
• ESB Integration Interaction Styles− SOAs in which applications communicate through reusable services with
well-defined, explicit interfaces. Service-oriented interactions leverage underlying messaging and event communication models.
− Message-driven architectures in which applications send messages through the ESB to receiving applications.
− Event-driven architectures in which applications generate and consume messages independently of one another.

IIB – Introduction • IIB – IBM Integration Bus
− NEON, MSQI, WebSphere MQ Integrator, WBIMB, WMB, then merged with WESB -> IBM Integration Bus
− Single engineered product for .NET, Java and fully heterogeneous integration scenarios
− DataPower is also considered a component in IIB ecosystem− DataPower continues to evolve for integration gateway use-cases

IIB - Demo − IBM Integration Console− IBM Integration Toolkit− IBM Integration Bus Web GUI− Basic IIB Commands (IIT Commands, IIB Commands)
− Some commands can be run only on the computer on which the integration node is running, and other commands can be run remotely
− We have IIT (IBM Integration Toolkit - BARs and Message Defs ) commands as well as IIB (IBM Integration Bus - Integration Node Admin) commands
− Start, Stop, List Integration Nodes, Start, Stop Flows, Retrieve Op Mode, IBM Integration Toolkit Debugging Demo
