3. © 2000, Progress Software Corporation 3 Building Distributed Applications n Internet B2B applications and services n Creating the global enterprise n Disparate systems acquired via mergers and acquisitions n Increase of disconnected users –Handheld, mobile n Growth of embedded systems A New Landscape

4. © 2000, Progress Software Corporation 4 Building Distributed Applications n Potential for explosive success  High-performance, massive scalability  Built on most common Internet protocols  TCP and HTTP n Heterogeneous (multi-company, multi-vendor)  Standard interfaces and data formats  JMS and XML  Comprehensive security, encryption and firewall support n Diversity in application styles and devices  Flexible Topology: 1  1 and 1  Many  Wide range of platforms & mobile devices  100% Java n Highly distributed, unpredictable environment  Fault-Resilient with guaranteed delivery and QoS  “Loosely Coupled” communications architecture

5. © 2000, Progress Software Corporation 5 Building Distributed Applications n Not optimized for the Internet n No support for disconnected users n Proprietary systems over private networks n Unwieldy and inflexible n Large footprint n Limited support for standards Limitations of Current Technology

6. © 2000, Progress Software Corporation 6 Frequent Limitations of current Technologies* n Forces “tightly coupled” synchronous model n Not designed for the Internet or firewalls n Inflexible & cumbersome n No guaranteed delivery n Large “footprint” & not easily embedded n Difficult to maintain or administer n No support for intermittent or mobile clients n No explicit support for XML * e.g., CORBA, COM, RPC or RMI, Native Sockets, Custom Programming on HTTP, or Proprietary Middleware

7. © 2000, Progress Software Corporation 7 Today’s Religious Divide for the Underlying Communications Architecture Choices: CORBA, COM, RMI, RPC & Messaging Favored for traditional Enterprise applications & simple web apps Choices: Messaging Favored for distributed Internet applications & Enterprise Integration Loosely Coupled Tightly Coupled Synchronous Application Servers Client/Server B2C Asynchronous Integration Brokers EAI B2B B2C

8. © 2000, Progress Software Corporation 8 Enter... Java Messaging n Service allowing Java-based applications to communicate n Two models: –Publish and Subscribe(1  Many) n Messages passed between publishers and subscribers via topics –Point-to-Point(1  1) n Messages passed between senders and receivers via queues

9. © 2000, Progress Software Corporation 9 Java Messaging Service (JMS) The Only Industry Standard for Messaging n Developed and maintained by Javasoft –Standardized since 1998 n A way for Java programs to interact n Embraced within J2EE specification n An API and set of semantics n A common programming framework for: –Point-to-Point (PTP) –Publish & Subscribe (Pub/Sub)

10. © 2000, Progress Software Corporation 10 Messaging Models Subscriber(s) Publisher Posts messages to a Topic Each receive messages on topics to which they register Topic = “Subject” of communication Available to “registered” participants Publish & Subscribe (1  Many)Topic ReceiverSender Queue = “Location” for the messages of a given type Sends message to a Queue Only one client receives the message, (but several receivers may share load) Point-to-Point (1  1)Queue

11. © 2000, Progress Software Corporation 11 Publish & Subscribe PublisherSubscriberTopic Price Increase New Flavor

13. © 2000, Progress Software Corporation 13 How is Messaging Being Used? n “E-Tail” n Supply Chain Management n Workflow Management n Data Dissemination / Integration n Distributed monitoring n Enterprise Application Integration

14. © 2000, Progress Software Corporation 14 E-Tailer: Business to Consumer Consumer Credit Bureau E-Tailer Message 2: “Credit Check” Message 1: “Product Order” Message 3: “Credit OK”

15. © 2000, Progress Software Corporation 15 Supply Chain Management: Wholesalers and Retailers Wholesaler Message 1: “Item on Sale” Message 2: “Place Order” Wholesaler SmallRetailerChainRetailer

16. © 2000, Progress Software Corporation 16 Workflow Management: Mobile Loan Processors Message 2: “ Loan Approved” MortgageCompany Message 1: “Loan Request” Loan Agent A Loan Agent B Message 3: “Need More Info”

17. © 2000, Progress Software Corporation 17 Limitations of the JMS Standard It Does Not Address n Security n Load Balancing n Fault Tolerance n Error Notification n Administration n Repositories n XML Support n Wire Protocols It Does Not Require n Support for Both Messaging Models n Transaction Support n Asynchronous Reply n Naming Conveniences for Topics & Queues n 100% Java
