CTS6-05 Why WebSphere is Better.ppt 2

.NETWebSphere/J2EE

Which one is best on the servers?

Selecting a Foundation for Your Server Infrastructure


? 50,000 customers worldwide? 2,800+ active ISV solutions running on WebSphere? 1M+ registered WebSphere developers? 93 out of Fortune 100 companies? Top 45 worldwide commercial and savings banks? 14 out of top 15 worldwide telecommunications firms? All 13 worldwide pharmaceutical companies? #1 in marketshare

WebSphere/J2EE Enjoys Strong Customer Adoption


Why WebSphere/J2EE is Better Than .NET

? Runs on any platform, including Linux? Strong distributed processing environment? Container concept makes programming easier? WebSphere maturity avoids 5 years of .NET rollout misery? Web services – better quality of support? Better performance in real-world workloads? Lower cost? Tighter security? Tooling provides greater programmer productivity

How do I easily access other applications and data in a consistent manner?

Challenges in Implementing Today’s on demand, Server-Side Applications


WebSphere Provides Stronger Environment for on demand Applications

? Transactions? J2EE designed from the ground up to support distributed

transactions (JTS, JTA)? .NET doesn’t have this support; must rely on legacy COM+

services

? Location Services? J2EE has JNDI directory services to find remote objects? .NET remote calls hardcode location of remote objects

? Connection Architecture? J2EE has J2EE Connector Architecture? .NET has no standalone architecture for connecting to

enterprise systems


WebSphere Provides Stronger Environment for on demand Applications (cont’d)

? Connectivity? WebSphere has broad MQ reach, high-performance message

broker to connect to virtually all systems and applications? .NET lacks MQ reach and has no high-performance broker

? Web Services? WebSphere has extended Web services with Service-

Oriented Architecture (SOA) concepts? .NET has no equivalent SOA construct? WebSphere has easier tooling to expose existing programs ? WebSphere Web Services Gateway makes it easy to manage

deployed Web services? Performance

? WebSphere scales well to multi-tier deployments? .NET best practices recommend single-tier deployment


? Code to efficiently manage program resources in a shared environment is complex and tedious

? Container frees the programmer from this work by providing these services transparently and declaratively

? Eliminate programmer-induced errors

.NET has no container concept

Container Concept Makes Server-Side Programming Easier

WebSphere Containers


Services Managed by the WebSphere J2EE Container

? Transactions (Container Managed Transactions)? Guarantees that each method executes within a transaction as configured ? Automatically starts, commits, and rolls back transactions

? Data integrity in multi-user environment (Container Managed Persistence)? Automatically loads and saves data upon transaction boundaries as

configured with “access intents.”? Automatically protects data accessed concurrently by multiple users

? Transparent performance optimizations? Caching and pooling

? Remote method calls? Automatically marshals data to remote containers

? Security ? Automatically enforces authorization and delegation policies

? Asynchronous Messaging? Automatically handles asynchronous in-coming messages via message

driven beans (MDBs)


It’s Smart To Use a Container

? Less coding required? Application programmers do not have to repetitively write difficult

code for each application? Declarative configuration encourages reuse of EJBs

? 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

Microsoft’s server environment will be unstable for the next 5 years because the remaining 98% of code has to be

re-implemented in .NET

A complete server platform, all built on J2EE, provides a stable environment

going forward

.NET Is Way Behind IBM In Platform Build-Out


WebSphere has a single, consistent programming model, based on open standards

One Consequence:Three Different Sub-Environments

? .NET Objects (NEW) ? New object model and Common Language Runtime? Runs new applications only

? COM Objects (LEGACY)? Legacy code represents 98% of Microsoft's current code base? Still used by Microsoft's "back office" servers

? Serviced Components (NEW+LEGACY)? .NET object that uses older COM+ services for transactions? Different operational characteristics

Let’s look at the whole picture…

Lower Costs

What about costs?


Microsoft Pricing

? Costs typically include both server license as well as Client Access License (CAL)

? Client Access License is required for any device that accesses the server? Windows Server 2003 Standard Edition (includes 5 CALs):

$999? Additional Windows CALs: $40/device

? This pricing methodology applies to all Microsoft servers? SQL Server 2000? SharePoint Server 2002 ? Office Live Communications Server 2003? Exchange Server 2003? Etc.

Who Has Lower Costs?

IBM

IBM middleware license pricing (Express) is typically competitive on Windows platforms and cheaper on Linux

Includes 1 year of maintenance and support

Performance advantages lead to lower overall costs

Stability of J2EE-based middleware means less financial churn

Microsoft

Microsoft middleware pricing can be more expensive

First year maintenance and support costs extra

Performance disadvantages require more servers and licenses

5-year.NET middleware roadmap means greater risks, higher costs
