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

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 cost Yearly Capex + Opex charges excluding licensing

Average hardware savings per application ~ 40% excluding WAS licensing!

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

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.

21

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!
