Success in e-commerce comes from delivering differentiated services via the Internet. The e-commerce race will go not to the company that delivers the first shopping cart, but to the company that delivers the most valuable services. Caching is a logical response to this need to deliver faster and more differentiated services on the Internet.

Its PowerTier application server provides dynamic caching. The server's PowerSync feature provides state replication among multiple application servers. Shared information in the PowerTier cache can dynamically change with the same integrity that back-end databases have traditionally provided, because PowerSync synchronizes these changes across multiple PowerTier caches. Some of the most innovative Internet applications are using PowerTier's dynamic caching to deliver differentiated services. FedEx uses dynamic caching of flight information to help support the world's largest logistics-optimization system.
