Getting Started There are some easy early wins! Identify areas of greatest pain Inefficiency Inflexibility Performance/reliability Identify areas of greatest opportunity Where small improvements get big returns Where existing infrastructure already supports some “gridness” Build a plan Short term: leverage existing grid enablement Short-Medium term: augment with better grid infrastructure Medium-Long term: build out application grid across data center $ ¥ £ € 06/06/09 ©2008 Oracle Corporation

Factors to Keep in Mind Not All Grid Enablers are Created Equal The More… Comprehensive Cross-stack integrated Live, production hot-pluggable Predictable Manageable … your infrastructure elements are, the more successful will be your application grid ©2008 Oracle Corporation 06/06/09 JRockit WebLogic Server Tuxedo Coherence

Take-Aways Application Grid is an approach to foundation infrastructure based on resource pooling and sharing 06/06/09 ©2008 Oracle Corporation Key Enablers Are Control Visibility Management Only Oracle enables Guaranteed, predictable performance True dynamic scaling Cross-stack management Key Benefits Are Efficiency Flexible scaling High quality of service
