7 Why Do Customers Want Application Portability? Flexibility to choose server platform Re-use old servers Scale up to more powerful server Improve reliability by moving to IBM zseries s Consolidate workloads to fewer servers Integrate systems from business acquisitions Software vendors can sell their solutions into more customer environments Avoid vendor lock-in Make it a strategic decision in your enterprise Never develop a non-portable application again!

10 What s Missing in the.net Programming Model? Transaction Processing!.NET Common Language Runtime does not support distributed transaction management! Older COM+ programming model must be used Serviced Components are the name for.net objects that inherit a class which provides access to COM+ transaction services Call outside of CLR to execute COM+ transaction services COM is a legacy programming model, different than.net objects D1-06 Why WebSphere Provides a Superior Foundation.ppt 19 On Demand Style Applications Need Transactions Commit Transaction Start Transaction Update Database 1 Update Database 2 Both updated Start Transaction Update Database 1 Failure Update Database 2 X Neither updated Rollback Transaction Restore database 1 D1-06 Why WebSphere Provides a Superior Foundation.ppt 20 CTS8-Why IBM is Better 10

11 J2EE Features Missing from the.net Programming Model WebSphere/J2EE formalized container concept.net CLR does not provide many container services WebSphere /J2EE Connection Architecture (J2EE/CA).NET does not have a formalized architecture for connecting to other environments (other than web services) WebSphere/J2EE JNDI.NET has no standardized architecture or services for locating and accessing remote objects D1-06 Why WebSphere Provides a Superior Foundation.ppt 21 Container Concept Makes -Side Programming Easier Containers provide an environment in which to run application components WebSphere/J2EE container simplifies the job of creating server-side applications CICS was the industry s first commercially successful container WebSphere Containers Web Container JSP Page Servlet RMI- IIOP EJB Container Enterprise JavaBean JAAS JMS JTA Java Mail JAF J2SE JDBC JAXP Connectors JAAS JMS JTA Java Mail JAF J2SE JDBC JAXP Connectors Database D1-06 Why WebSphere Provides a Superior Foundation.ppt 22 CTS8-Why IBM is Better 11

Transaction management.net must rely on legacy COM+ 2. Provide a single-level store programming model so that programmers are free from issues of when and how to load data.net programmers must write code 3. Automatically manage pools of EJBs to improve overall performance.net programmers must write code 4. Automatically hydrate/dehydrate user components to share system resources and support more clients.net programmers must write code 5. Automatically manage pools of DB connections to improve performance and support more clients.net data providers are not required to pool DB connections (but some do) D1-06 Why WebSphere Provides a Superior Foundation.ppt 24 CTS8-Why IBM is Better 12

13 WebSphere/J2EE Container Function Not Provided by.net Framework 6. Provide J2EE/CA connection services, including pooling, security, and management.net has no standardized architecture for accessing legacy systems 7. Supports the distribution, addressing, and communication required for distributed components.net must rely on legacy COM+ and DCOM 8. Reads runtime requirements from deployment descriptions to facilitate simultaneous component reuse by different applications.net security policies must be in the code COM+ transaction declarations must be in the code 9. Provide asynchronous Message-Driven Bean (MDB) initiation.net programmers must write MSMQ 3.0 triggers 10. Provide platform transparency.net only runs on windows D1-06 Why WebSphere Provides a Superior Foundation.ppt 25 It s Smart To Use a Container Easier to write good code Application programmers do not have to repetitively write difficult code for each application Fewer bugs Resource management in multi-user environment is complex, is more likely to have bugs than business code, and those bugs are more difficult to correct More flexible administration Declarative configuration means that administrators can change policy without waiting for a programmer to make code changes These are advantages over.net D1-06 Why WebSphere Provides a Superior Foundation.ppt 26 CTS8-Why IBM is Better 13

D1-06 Why WebSphere Provides a Superior Foundation.ppt 33 WebSphere/J2EE: A Consistent Model for Security Declarative, Roles-Based Access Control Application Provider Application Assembler Security Administrator Developers create application components E.g. Build a method to delete accounts Declare what Role is required to access each resource. E.g. Supervisors can delete Accounts Assign Roles to Users E.g. Assign Supervisor Role to Kate use LDAP server as the user directory JSPs, servlets, EJBs, etc. are all protected with the same model D1-06 Why WebSphere Provides a Superior Foundation.ppt 34 CTS8-Why IBM is Better 16

17 Microsoft Mixed Security Models COM+ role-based access control model is declarative.net role-based access control is specified in source code [PrincipalPermission(SecurityAction.Demand,Role= Teller )] public void CreateAccount(){.} The two models have different class hierarchies and define roles differently This means that serviced components (COM+) have a different security model than pure.net components Inconsistent models tend to provide looser security Increased chance of mistakes, oversight, conflicts D1-06 Why WebSphere Provides a Superior Foundation.ppt 35 On Demand-Style Application Requirements Flexible deployment Build web solutions fast and easy Superior performance and scale Strong security Lower cost Reliable enterprise operation TCO Five Years of Misery Frequent Changes D1-06 Why WebSphere Provides a Superior Foundation.ppt 36 CTS8-Why IBM is Better 17
