UNIX-to-Linux replatforming

Services


Discouraging Trend for UNIX

• Unix workloads increasingly dominated by LOB apps, database

• Generic network and Web infrastructure workloads typically already moved or moving off Unix to Linux and/or Windows

• Unix migration plans tend to be deep; once migration starts, nearly half of Unix server units are vulnerable to replacement

Defined target environment and established migration roadmap

125 LPARS remain for foreseeable future

80 LPARs to be decommissioned without replacement

95 LPARs (26 apps) moving to x86

28 apps migrated to date - including critical Tivoli environment that monitors all bank systems

Outcome of initial U2L analysis - 32 LPARS decommissioned to date

Remaining 125 LPARS to move IBM Midrange systems temporarily; will be migrated in 2nd Step through 2016

Consumer, financial and property information

Information, analytics and services provider migrates Solaris to Linux/x86

• Strategic corporate initiative to re-host existing IT infrastructure and deliver next-generation cloud computing, technology, security and infrastructure management services.

• Project goals – Implement standardized Dell x86 platform; reduce hardware footprint – Leverage virtualization technology and enable better scalability to

support future growth requirements – Enhance application availability and performance – Reduce costs

• Critical success factors – Standardized technology platform – Same or better performance post re-platform – Like-for-like or improved production, non-production, and DR functionality – Cost savings resulting from reduced UNIX / Solaris license costs


Information, analytics and services provider

UNIX application environments in scope

• Application Set 1 – 1.3M LOC/135 databases, >30 TB data – Java Tier Services running on WebLogic Application Server, associated

C/C++ applications and shell scripts, 33 client applications/dependencies – Planned enhancements:

– Moving WebLogic to jBoss (and implementing stateless environment) – Upgrading from Oracle 9i standalone to Oracle RAC 11g to enhance availability

and throughput – Upgrading Java

• Application Set 2 – 2M LOC/6 DBs – WebLogic Application Server, associated C applications and shell scripts – Planned enhancements:

– Moving WebLogic to jBoss – Upgrading EJB2 to EJB3

• Oracle EBS 11i (Core financial and several other modules) – Planned enhancements

– Upgrading Oracle DB



Project details

• 12-week planning process – Workshops – set direction and build communication plan – Data gathering – tool-based gathering, source code review, interviews – Analysis – size workloads, determine dependencies – Project documentation and wrap-up

• 3 main migration project phases 1. Primary Development Phase:

– Deployment of new infrastructure, prod and non-prod environments, excluding prod database data synchronization and cutover from the UNIX databases.

– Majority of the code migration occurs in this phase; client application teams upgrade (and test) all client applications

2. Database Cutover Phase: focused on repointing the existing services (still running on WebLogic on UNIX) to the new production database.

3. Services Migration Phase: Code re-sync, then migrated services and client applications are deployed and the UNIX databases are retired.

• Extensive three-phase testing process

Summary of anticipated migration results

• ~9 months project

• Hardware impact – Reduction in overall # of systems leveraging new lower cost virtual

environment once in new Dell Data Centers – Going from 12 physical boxes to 3 physical boxes for Java applications – Reducing cores devoted to Oracle databases ~12%

• Gained scalability to handle future growth of both application and database components

• Oracle Real Application Cluster (RAC) to provide decreased outage windows, automated load sharing, enhanced HA

• App. Set 1 - – Stateless environment will enable zoning and workload balancing – New environment will include extended infrastructure to allow single

JVM instance per OS


Salesforce.com Scalable platform achieves 2x the performance at 10x lower cost Challenge – Achieve more cost-effective scalability for its global database infrastructure to accommodate rapid customer growth.

Results –

• Achieved rapid provisioning of new servers; cut deployment time by half

• Doubled database performance, giving customers faster access to data

• Reduced TCO 10x compared with the previous infrastructure, enabling the IT group to build in more redundancy and help ensure greater availability for customers

• Made room for new, innovative services and customer growth by reducing data center floor space 30 percent

Basing the future case on the present

• Missed requirements or misalignment with business processes cost significantly more late in a project or after delivery

• Dell Re-architecture software and method bases the future modernized application on the assets and business usage of the legacy system

• The risk of the new application not meeting 100% of the current state functionality is vastly reduced
