Middleware 2002
- 1. Making Sense of Middleware Andre Yee “Integrating Your eBusiness Enterprise”
- 2. Context is Everything Personal background – Developed distributed middleware technology for the past 8 years. – Author of articles and books including “Integrating Your eBusiness Enterprise” (SAMS Publishing, April 2001) – Currently in the Internet Security arena w/ NFR Security. Middleware synonyms – EAI (Enterprise Application Integration) – B2Bi (B2B Integration – e-Business Integration
- 3. Agenda The Enterprise Integration Challenge Making Sense of Middleware Technology Evaluating Middleware - What’s right for you?
- 4. Trends Driving the EAI Challenge Growing Adoption of Packaged Applications Base of Business Critical “Legacy” Systems Internet is driving Open B2B Collaboration Complexity of Changing Business Processes – M&A, Consolidation, Re-engineering
- 5. The Need For Application Integration Source: Aberdeen Group, October 2000
- 6. The Integration Problem “70% of all code written today consists of interfaces, protocols and other procedures to establish linkages among various systems” “30% of entire IT budget is spent on building, maintaining, and supporting application integration”
- 7. Middleware - The Answer to the Integration Challenge What is Middleware? “Connectivity software that consists of a set of enabling services that allow multiple processes running on one or more machines to interact across a network.” CMU Software Engineering Institute “Middleware is software that connects applications, allowing them to exchange data” CIO article, May 2001.
- 8. Why Middleware? Preserve and leverage existing information technology systems Bridge diverse “islands of automation” Purchase and integrate “best of breed” offered by independent software vendors
- 9. Disorder Today Application Application Application Application Application Application Application
- 10. Order Tomorrow Application Application Application Application Application Application Application EAI But, what is EAI or Middleware Technology?
- 11. Integration Broker Vendors Say: Message Brokers Application Application Application Application Application Application Application
- 12. Application Server Vendors Say: Application Servers Application Application Application Application Application Application Application
- 13. Distributed Object Guys Say: Let’s look at middleware taxonomy... Distributed Objects Application Application Application Application Application Application Application
- 14. Business Process Data-Access Messaging-Transport Object-Transactional Integration Brokers The Middleware Taxonomy Application Messages Data Application Interface Business Application Data Application Components Asynchronous Protocol
- 15. 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
- 16. OracleOracle SybaseSybase MS SQL Server MS SQL Server Client SQL RequestClient SQL Request Database Gateway Database Gateway SQL Joins Distributed SQL Request SQL Request/Replay SQL Request/Replay SQL Request/Replay Integration with Data Access Middleware
- 17. 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)
- 18. Integration with Messaging Middleware ApplicationApplication MessageMessage ApplicationApplication MessageMessage MQM/MOM QueueQueue MessageMessage MessageMessage MessageMessage Message created and sent to a message queue Message received from a queue and processed Figure 2.3
- 19. 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
- 20. Application Server Integration with Application Servers Web Client Web Client HTTP Requests Integration Logic Integration Logic EJB EJB ERP CRM Legacy DB Transaction Management
- 21. 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
- 22. Integration with Integration Brokers AppCAppA Source Adapter Target Adapter Transformer Link Message Reply Adapter AppB Hub Filter
- 23. 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
- 24. 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
- 25. 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

Editor's Notes
- <number> 06/26/14 Complexity of Changing Business Processes - Whether it’s driven by M&A or simply competitive forces, companies have to be able to quickly adapt to change. The challenge is how to adapt your business process without making wholesale changes to your applications..

- <number> 06/26/14 The concept of how MQM works is fairly simple … Application A creates a message and sends it to a queue using the MSMQ API. Application B receives messages from the queue or dequeues the message by using appropriate MSMQ API calls and processes the message.
