  1. Rob Clark Director, Product Management Oracle Application Server J2EE & Web Services Oracle Corporation

  2. J2EE and .NET: An Objective Comparison

  3. Presentation Goal • Evolve and Define Our Manifesto • We Believe in Choice • We Believe in a Heterogeneous World • We Believe in Competition • We Believe in Open Standards • We Believe in Platform Neutrality • We Believe in the Community Process

  4. Agenda • Evolution • Software Architectures • Component Models • .NET Strategies • Presentation Layer • Co-existance • Domination • Complexity & Abstraction • Today’s Architectural Reality • Understanding the Comparison

  5. Evolution

  6. Life

  7. Mankind

  8. Technology

  9. Agricultural • Mechanical • Manufacturing • Transport • Communication • Electrical • Computing • BioTech • NanoTech

  10. Computing

  11. Mainframes • Minis • Desktops • Networks • Internet • Pervasive • Wearable • Grids

  12. J2EE or .NET

  13. Evolutionary Flow Manage All Your Everything Green Screen Mainframes / Minis

  14. Evolutionary Flow Manage Data & Data Logic Manage Program & Business Logic Rich Windows Client Database Server PC Desktop / Workstation

  15. Evolutionary Flow Manage Your Content & Applications Manage OS & Program Logic Manage All Your Data Browser & Productivity Applications Clients Database Server Application Server

  16. Evolutionary Flow Presentation Layer Business Logic Data Standards Device DisconnectedProductivity heterogeneous, loosely coupled

  17. Component Model Evolution Web Services Univ. Types (XML) Components (Java2TM & .NET) Server Extensions (CGI, ISAPI, NSAPI) Standard Protocol (HTTP) Loose Coupling (MOMs - WANs) Interfaces (CORBA- LANs) RPC (DCE - LANs) Encapsulation (Sub-Routines and Procedures) 1975 1980 1985 1990 1995 2000 2005

  18. .NET Strategies

  19. What’s the Next Logical Step?Web Sites to Web Services Browsers HTML Web Presentation EJBs BusinessLogic XML Databases Firewall External Applications Application Server Why is this so important?

  20. The .NET Strategy Public UDDI Registry / Passport SOAP SOAP external firewall IIS WSDL ASP.NET Sharepoint Security Login Server / Passport SOAP internal firewall BusinessLogic .NET J2EE AD data firewall SQL SERVER ORACLE

  21. Coexistence Manifesto • Open Application Server Platform • J2EE • Interoperate, Enhance, Migrate • Make .NET Secure • Keep .NET Departmental • Protect Your Investment

  22. The Productivity Sacrifice • .NET • Internally Proprietary • Externally Open • VS.NET Perceived Productive • J2EE • Internally & Externally Open • Portable • Perceived Complex & Difficult

  23. The Cost Comparison • .NET • Microsoft Controls the Price • Microsoft Are Often Giving It Away • Purchase the OS, Server and Tools From One Vendor • J2EE • At Least 30 Different Vendors • Purchase OS, Server and Tools From Many Vendors • Price Points From Free to Price Competitive to Microsoft and Beyond

  24. Marketing & The Maturity Paradox • .NET • First Release – 2001 • Business Strategy • Massive Platform Marketing Budget • J2EE • First Release – 1998 • Community Process • Vendor Brand Marketing

  25. Complexity & Abstraction

  26. Technology Drivers for J2EE and .NET • Internet Is Ubiquitous • All Users, Information, Applications On Internet • Internet Becomes Programmable • Applications Conform to Service-Oriented Architecture • Services are Seamlessly Integrated • To Automate Business Processes • Services Becomes Accessible Ubiquitously • Anytime, Anywhere, Any Device via Portals • Services Use Resources On-Demand • Network, Storage, CPU, OS Resource Virtualized to Grids

  27. The Technology Vision Platform Collaboration Best of Breed Applications Enterprise Management Management Tools Development Tools IDE Application Platform APS Information Platform Enterprise Management Grid Services Resource Virtualization Cluster Services Networked (SAN, NAS) Storage 32-Bit, 64-Bit (IA, RISC) Processor TCP/IP, 1000-BaseT Fast Interconnects Network

  28. SOA Infrastructure Platform IDE & Personal Productivity PRODUCTIVITY TOOLS Provisioning, Monitoring & Management MANAGEMENT INFRASTRUCTURE PKI Svcs, ID Mgmt Svcs, Federation, Directory & Metadata Content Mgmt, Multichannel, Portal, Personalization Integration, BPM, BAM SOA Runtime SERVICES INFRASTRUCTURE Transactions, Messaging, Naming, Connectors, Metadata Mgmt., Registry Cluster & GRID Services Process, Memory, Resource Mgmt. Topology and Policy Mgmt. RESOURCE INFRASTRUCTURE Network, Disk I/O, Protocol Mgmt.

  29. Today’sReality

  30. open source IIS Apache community process J2EE .NET Oracle 9iAS Windows 2003 Windows, Linux, Solaris, HP-UX, Tru-64, AIX, OpenVMS Windows 2003 32 bit or 64 bit Intel, RISC … Intel Only white box black box Logical Architecture Comparison NetworkEdge Framework Application Server Operating System Hardware Platform

  31. Black Box vs. White Box • Application Servers Should NOT be in O/S • Vendor Competition • O/S and Hardware Independence • Undocumented Features • Back Doors • Patches and Upgrades • Free Reference Architectures • Proven Community Design Patterns

  32. Understanding the Comparison:Product Versus Specification

  33. What is 1° of Separation? • Basic .NET Vision: • Tightly Integrate All Fine Grained Components and Languages at Runtime • Loosely Integrate Heterogeneous Applications With XML Web Services • Communicate Via XML • Smart Client Not Just Browser to Server • Make MS Pivotal in the Architecture

  34.

  36. .NET is a Business Model • XML Web Services Sells • Smart Clients • Microsoft Servers • Developer Tools

  37. Windows Lock-in MS Own Perceived Weaknesses Marketing Campaign Enterprise Pain Points Deconstructing Microsoft’s View? • Run Existing and Forthcoming .NET Framework Applications • Richer End-User Experiences • Improved Reliability • Increased Performance • Stronger Security • Ease of Deployment • Maximum Scalability • Integration with Existing Systems • Improved Support for Instrumentation • Easy, Flexible Management http://msdn.microsoft.com/netframework/productinfo/topten/admins.asp - 14 August 2002

  38. J2EE vs .NET The Product Paradox Application System Initial flawed steps to “specification” ECMA and Project Mono

  39.

  40. Three Key Differentiators • Open Community Model • One Language Many Platforms • API & Development Model, Free Reference Implementation, Proven Design Models • Business Model • Any Language One Platform • Fragmented Badged Product Stack

  41. Protect &Survive Talking to Your CTO

  42. Key Facts : Investment Protection • Open Standards • Portability of Solution Between Vendors • Operating System Independance • Hardware Platform Independance • Scale Up, Scale Out • High Power Proprietary Machines • Commodity Hardware, Commodity OS • Heterogeneous Environments • Ability to Negotiate with Suppliers

  43. Key Facts : Operating Systems • Open Middleware • Same Application Deploy on any Platform • Linux Growing as Secure Commodity Platform • Hardened Linux • Full Support on • Windows • Secure Enterprise Deployments Typically Target • Solaris • HPUX • AIX • TRU64 • OpenVMS ……

  44. Key Facts : Hardware Platforms J2EE on Any OS All Major Unix / Mainframe Solaris, AIX, HP-UX, Tru64 OpenVMS, zLinux Windows Linux In Any Configuration 64 Bit OS 32 Bit OS On Any HW Architecture SMP 4,6,8,12,6,32 CPUs Blades Racks 1-2 CPUs With Zero Application Code Change

  45. Key Facts : Productivity : Lifecycle • Stack Management & Support • Upgrade Cycle, Patching & Certification • Testing Strategies • Software Configuration Management (SCM) • Black Box vs White Box • API Reference Models • Framework Documentation • Stability and Risk • Software Licensing Agreements

  46. Key Facts : Productivity : Tools • J2EE Has Best of Breed Tools • Eclipse • JBuilder • Macromedia DreamWeaver MX and UltraDev • Rational Rose and TogetherJ • JDeveloper • Sitraka JProbe, Mercury LoadRunner …. • Design Patterns • Struts, ADF, MVC, Wakesoft • O/R Mapping Layers • Toplink, Cocobase

  47. Summary • Complex Debate : Understand What to Compare & How -: RELIGION • Plausible Benchmarks Do Not Exist for the Choice -: MARKETING • Understand Your Environment-: EVOLUTION • Watch the Emerging Interoperability Story -: REALITY • Surveys Point to an Interesting Result-: WIN THE PRESENTATION TIER
