Object Management Group Focus on Interoperability • There will not be consensus on hardware platforms; • There will not be consensus on operating systems; • There will not be consensus on network protocols; • There will not be consensus on application formats. There must be consensus on interoperability. 10/7/2020 Copyright © 1999 Object Management Group 4

Object Management Group Who’s Using CORBA? • Wells-Fargo Bank – Integrate all legacy systems – Home Banking, ATMs • More Banks & Financial Companies: – Bank. Boston, Banque Paribas, Britannia, Capital One Financial Corporation, Chemical Bank, Credit Suisse, Dresdner Bank AG, Macquarie Bank, Nations Bank, Nomura International Securities, Charles Schwab & Co. , Commerzbank Capital Markets, Chicago Stock Exchange 10/7/2020 Copyright © 1999 Object Management Group 6

Object Management Group Bank. Boston 1998 ROI Study • CORBA Project ROI - Raw Figures: – Quantified Return-on-Investment for EMSTR Analytics was 627%; – Payback period was 7. 3 months. • More payoff than could be quantified: – More timely and more accurate information to the traders – New and deeper analytics. – Making the bank’s analytics system available to its customers • These benefits overwhelm the quantified benefits 10/7/2020 Copyright © 1999 Object Management Group 7

Object Management Group More CORBA Users. . . • UK Immigration Department – Suspect Index System • CNN Interactive – News feeds from hundreds of sources on multiple machine types and formats are managed with CORBA • Pratt & Whitney – Program Planning and Control for jet engine production • Matra Datavision – integration of EUCLID QUANTUM software for CAD/CAM • Aircraft Manufacture: Boeing, Airbus 10/7/2020 Copyright © 1999 Object Management Group 8

Object Management Group Still more CORBA Users. . . • AWACS Systems Integration – Also US Air Force and Navy • Retail: The Gap; Home Depot • Transportation: DHL, Fedex, Sabre Cargo. Manager, German Railway Company, Port of Singapore 10/7/2020 Copyright © 1999 Object Management Group 9

Object Management Group About CNN Interactive • A family of web sites – – – – CNN. com All. Politics. com CNN. com/ Custom. News (with Oracle) CNNSI. com CNNen. Espanol. com (Spanish language) CNNem. Portugues. com (Portuguese language) CNN. passagen. se (Swedish language) • Staff in Atlanta, Washington DC, Sweden, Latin America, Asia 10/7/2020 Copyright © 1999 Object Management Group 10

Object Management Group CNN Traffic Levels • Amongst the busiest sites on the web – 150, 000 - 250, 000 hits per minute – 77 million page views per week, growing at 9% per month – Estimated at 11. 5 million unique users per month – 6 T 3 s feed Atlanta; web site replicated in London and Japan • Also provides content to partners like Pointcast, Pagenet – 65, 000 users in 500 other news organisations – 300, 000 email subscribers – 150 other co- branded Web sites 10/7/2020 Copyright © 1999 Object Management Group 11

Object Management Group CNN Software Requirements • Support creation and distribution of content – Multiple internal server platforms NT, Solaris, Netscape – Multiple outstations across the world – Multiple media formats – Sub-editors used mixed Windows & Mac client platforms • Need to separate view from content – External customers need different transmission formats etc • Applications must work together across Operating Systems and languages 10/7/2020 Copyright © 1999 Object Management Group 12

Object Management Group News Content Servers • CORBA-based store for structured news content: – No embedded formatting - object tree structure – Win 32 and Java content creation tools populate tree – Client applications walk tree to extract content (e. g. to send to email subscribers, or generate web content) 10/7/2020 Copyright © 1999 Object Management Group 13

Object Management Group Based on CORBA Event Service • CORBA event services provide asynchronous notification to multiple listeners by one or more event generators – One of the standard suite of CORBA services • Used by CNN to handle wire services – Stories from AP, Reuters etc are redistributed within CNN over CORBA event channels – Each language has its own channel – Listeners can include knowledge base to allow them to filter content, delivering only stories of interest to editor’s desk 10/7/2020 Copyright © 1999 Object Management Group 14

Object Management Group Application Services • Live on the “CORBA bus” – Deliver common services • e. g. “Magic Mover” loads content into Web servers • Used independently of development language, platform • “For the most part, we have put these services on the bus and forgotten about them” 10/7/2020 Copyright © 1999 Object Management Group 15

Object Management Group Server for User Polls • CNN is exploring using ORBs as integration point for all web- based services – Uses the Visi. Broker ORB bundled with Netscape Enterprise Server 3. 0 • Allows computationally-expensive services to be moved off server machine – e. g. database lookups, advertisement serving – Again, common interface architecture is a big win • Test case - polling server for gathering opinions – Orbix 2. 2 MT on Sun 2170 handles millions of votes per hour 10/7/2020 Copyright © 1999 Object Management Group 16

Object Management Group A CNN Quote. . . • “CORBA has provided a robust and elegant framework for us to build a distributed architecture. In addition, the ORB has also become the integration point for our various operating systems and implementation languages. Based our experiences, we expect to continue to build products based on CORBA. ” • Al Issa • Director, Software Development • CNN Interactive 10/7/2020 Copyright © 1999 Object Management Group 17

Object Management Group CORBA 3. 0 Adds - • Improved Java and Internet Integration – Java-to-IDL (reverse) Mapping – Firewall Specification – CORBA Object URLs • Quality of Service Control – Asynchronous Invocation/Messaging – Invocation Qo. S Control – Realtime, Minimum, Fault Tolerant CORBA • CORBA Component Model – Objects Pass-by-Value – Component container • Transactional, Persistent, Secure – Distribution Format – Scripting Language Specification 10/7/2020 Copyright © 1999 Object Management Group 34

Object Management Group CORBA Component Model (CCM) • CORBA is great for building Enterprise and Internet applications • But, of the thousands of CORBA usage patterns, a few stand out • CCM packages up these successful patterns, including – – – POA servant management Transactions and Persistence Security Event Handling Configuration Interface Connection and Assembly • This speeds and simplifies application building, and ensures success 10/7/2020 Copyright © 1999 Object Management Group 35

Object Management Group What this Means to You: • CCM Applications are very compact: – Much less code required – Developer code devotes to the business problem • CCM Applications are easier to code: – Only successful patterns included in CCM – Much code is generated automatically – In declarative languages derived from IDL • CCM Applications are Modular: – Components assemble into applications – Combine commercial, in-house, and custom components – Standardized Assembly, Packaging, Distribution, Deployment • CCM Applications scale to Internet and Enterprise – Patterns known to scale well – Vendor experience used to build and tune products – Resource handling coded automatically in the best way 10/7/2020 Copyright © 1999 Object Management Group 36
