IBM WAS + J2EE / JEE
additions and overhead
Introduction
 Generally, a large amount of any customer’s in-house developed applications will
be developed in the Spring framework
 Because of this, these applications have no dependencies on proprietary J2EE /
JEE add-ons. While these proprietary add-ons are arguments used in the past to
sell IBM WAS
 Because the majority of COTS apps also support tc Server out of the box, and
because of the relatively low costs of tc Server (>90% less), migrating to tc Server
has a strong business case and lowers TCO significantly

tc Server Benefits over IBM WAS / Oracle Weblogic
• Licenses for tc Server are a fraction of the cost of WebSphere / Weblogic and
straightforward: no big surprises during painful and costly audits
• No need for proprietary expensive hardware (pSeries / SPARC)
• Lightweight, so low on memory / CPU consumption. Drives further increases in
hardware consolidation ratio
• Elastic Memory for JAVA (EM4J)
• No dependency on J2EE / JEE, so no vendor lock-in. While being binary
compatible with Tomcat
Cost
• Leveraging VMware tooling such as AppDirector for fast provisioning
• Cloning and network fencing production environments for testing purposes
• Hybrid cloud compatible (x86) or CloudFoundry
Agility
• Use VMware HA capabilities for resilience in the datacenter
• Use VMware Site Recovery Manager for Disaster Recovery testing and
execution
• Single processor architecture (x86) is less complex to troubleshoot / recover
Stability

10. 10
tc Server Business Benefits – What’s in It for Me?
• Much cheaper to run so the business can be more effective in a price
competitive environment
Cost
• Provide new environments within minutes / hours to test new functionality
• Easily copy production environments in order to do proper acceptance testing
and roll-out new business capabilities and features faster
• Develop faster and never have to wait for storage, compute, networking
upgrades with the use of Hybrid Cloud technology
Agility
• Downtime reduction by leveraging standard out of the box disaster recovery
capabilities
• Reduction of down time because the “high availability” functionality is taken
care of in the infrastructure layer and not in the application layer
• Reduction of “integration” issues by leveraging robust and proven x86
technology instead of proprietary platforms
Stability

Business Case at a Large European Bank
# Datacenters: 4 WebSphere Platform: pSeries
# Applications: 200 Main database vendor: Oracle
# WAS instances 1200 Dev framework Spring
Yearly occurring SnS costYearly Capex + Opex charges excluding licensing
Average hardware savings per application ~ 40% excluding WAS licensing!

Business Case (cont’d)

What Applications Can Easily Be Migrated?
Does the application have WAS
specific dependencies?
Use Spring Migration Analyzer
Is the application custom
development or packaged
software?
Migrate!
See migration options
Bonus option: does the
database run on Oracle without
Oracle-specific coding?
Does the vendor support tc
Server, or are they willing to
support tc Server?
Do not migrate at this time. This
is approximately 20% of
applications.
Combine migration with
vPostgres migration
+ Single processor architecture
+ Financial Benetis

Determining Migration Priorities
• Migrate WAS to tcServer x86
• Migrate WAS HTTP to RHEL
Apache x86
• Keep AIX Oracle dBase
Scenario 1
• Migrate WAS to tcServer x86
• Migrate WAS HTTP to RHEL
Apache x86
• Migrate Oracle dBase to x86
Scenario 2
• Migrate WAS to tcServer x86
• Migrate WAS HTTP to RHEL
Apache x86
• Migrate AIX Oracle dBase to
vPostgres
Scenario 3
1
• Migrate as much WebSphere
Application Server (WAS)
workloads to tc Server as
fast as possible
2
• Follow single processor
architecture per application
where possible (including
database to x86).
3
• Migrate database to
vPostgres where possible.
Majority of in house
developed applications is
compatible!

Objection Handling Moving from WAS to tc Server
“Most applications only run on WebSphere!”
Based on empirical evidence we can say that 45% of the applications can be
migrated to tc Server without any changes. About 35% of the applications need
some minor changes (1 hour per app) excluding testing. Some 20% if the
applications have a heavy dependency on Enterprise Java Beans (EJB’s).
“Tomcat lacks the manageability and tooling compared to WAS”
tc Server is Tomcat with an Hyperic agent which provides you with monitoring
capabilities that go beyond the standard tooling that comes with WAS.
“WAS provides scalability, availability and support for clustering”
VMware provides scalability and availability with the standard features of the
vSphere platform. Other specific VMware features such as Elastic Memory for
Java (EM4J) will enable more stability and scalability. Proprietary hardware
based WAS solutions are usually based on a scale-up model while tc Server is
based on a scale-out model just like most modern cloud enabled applications.

19. 19
Objection Handling: Moving from pSeries to x86 vSphere
1. Automated response in case of hardware / power failures
2. Hardware vendor agnostic (HP / Cisco)
3. Disaster Recovery Automation (including re-IP) with SRM
4. Application based DR testing as opposed to machine based DR testing
5. Ability to monitor and report on Disaster Recovery Capacity available
6. DevOps capabilities to snapshot production to DTA environments
7. Performance analysis reporting incl. Storage, Network, Compute & App
8. Datacenter migrations possible without re-IP using VXLAN / NSX
9. SDDC means less physical appliances for firewalls, load balancers, IDS
10. Requires les OPEX and CAPEX to run (better price performance)
11. Performance of pSeries matches that of Intel CPU machines

(Thanks to Kevin Closson for this overview)
As you can see, in this list the E5-2690 has the highest TpmC rating per core (except for the Power6 which
is not Intel) - Making this CPU an excellent choice for DB consolidation.
The E5-2643 is not listed on TPC.org – however, the 2643 is half a 2690 (same cores) so the performance
per core is equal.

Call to Action
 Ask how much WAS LPAR’s are running within your organization
 Review the lifecycle of your “proprietary” hardware
 Ascertain the split between in-house developed and Commercial
Of The Shelf (COTS) products
 Use Spring Migration Analyzer to ascertain / prove the level of
migration effort
 Ask the programmers what kind of framework they are using
(Spring)
 Ask the programmers what platform they use to develop their
application (often already Tomcat)
 Contact your VMware rep and ask what he can do for you!
