IT Priorities for Challenging and Changing Times

• Examine and cut capital expenditures

• Become more efficient to reduce operating costs

• Deliver even better service, system availability and • Deliver even better service, system availability and

Current IT Infrastructures Impede Cost Reduction and Efficiency

• Dedicated silos are inefficient

• Sized for peak load

• Constrained performance

Middleware

• Constrained performance

• Difficult to scale

• Expensive to manage

Oracle Consolidated Stack

• Oracle single vendor, OEM single mgt console

• Upgrades and Patching simplified, streamlined

• Fewer contracts, renewals, vendor interdependencies

• Eliminates obstacles to timely upgrades - can only upgrade as fast as the last piece in the stack is certified with all the others

Standardization: Single Stack Value

• Reduced complexity

• Simplified solution stack reduces finger pointing, accelerates problem resolution

• Increases utilization and database and application uptime• No down-time for storage provisioning or migration

• Managing storage pool vs. islands• Managing storage pool vs. islands

• Single vendor cross-platform integrated solution• Bundled and tested as one solution

• Same cross platform tools to install, configure and manage

• Avoids delays of upgrading any single element because of multi-vendor certifications
