The document discusses optimizing application infrastructure by moving from a generic approach to an engineered approach using Oracle technologies. It describes how generic infrastructure treats all workloads equally and may not optimize for cost or performance needs. Oracle offers engineered systems like the Private Cloud Appliance to optimize for cost through features like integrated software and hardware. It also offers Exalogic to optimize for extreme performance requirements through tight integration and software enhancements. Case studies show customers achieving significant cost savings and performance improvements versus generic infrastructure.
