Middleware - The Answer to the Integration Challenge
Why Middleware?
Disorder Today
Order Tomorrow

The Middleware Taxonomy
Making Sense of Middleware - Data Access Middleware
Data Access Middleware
Focused on client-server data access
Synchronous Request/Reply model
ODBC, Database Gateways
Vendors: Merant/Data Direct, Information Builders EDA/SQL
Integration with Data Access Middleware
Making Sense of Middleware - Messaging Middleware
Messaging Middleware
AKA Message Queuing Middleware or Message Oriented Middleware (MOMs)
Focused on transporting application data via asynchronous messaging protocols
Vendor/Products: IBM MQ Series, Microsoft MSMQ, Java Messaging Service (JMS)

Integration with Messaging Middleware
Making Sense of Middleware - Object Transactional Middleware
Object-Transactional Middleware
Focused on a distributed object, component or transactional model
Most products support all three
Requires custom component code to bind applications or data resources
CORBA, TP Monitors, Application Servers
Vendor/Products: BEA Weblogic, IBM Websphere, Microsoft MTS, BEA Tuxedo, IBM CICS
Integration with Application Servers
Making Sense of Middleware - Integration Brokers
Integration Brokers
Focused specifically for application integration
Integration Broker components include messaging middleware, transformation engine, rules engine, adapters, integration design tools.
Content based routing is a distinctive feature from the basic messaging middleware
Parameterized data mapping approach rather than Code-driven approach
Vendors/Products: Webmethods, Vitria, SeeBeyond, Tibco, IONA

Integration with Integration Brokers
Variations on Theme
B2Bi/Web Services Brokers
Evolved from application servers or integration brokers
Utilize HTTP as primary protocol
Based on XML, XML Schema, XSLT, SOAP
Business Process Integration
Focused on business process rather than business data
State management of “long running transactions”
Extensions to application servers or integration brokers
Evaluating and Selecting Middleware
Consider the required integration model or pattern
Intra-enterprise or Inter-enterprise
Client/Server data access, inter-application data exchange, composite application integration
Consider scope and complexity
Simple integration or complex global multi-application integration
Consider use of standards
XML, XSLT, JMS, JCA

Evaluating and Selecting Middleware
Evaluate Technology Criteria *:
High Availability
Transactional
Performance
Scalability
Adapters
Integration Design Tools
Evaluate Vendor Criteria *:
Viability
24x7 Support
Proven Case Studies on ROI
* Partial listing only
