What is an enterprise content delivery network (eCDN) and how do I use OracleAS Web Cache to build one?
Within the enterprise intranet, the hierarchical caching features of OracleAS Web Cache enable customers to more easily create eCDNs, which provide shorter response times for remote users. Compared with full-scale application mirroring and remote database replication, eCDN is a more manageable and cost-effective model of distributed computing because it enables remote assembly and delivery of content — using OracleAS Web Cache — while maintaining centralized management of application logic and data. To configure an eCDN, customers simply deploy additional OracleAS Web Cache instances in branch offices. With a few small network configuration changes, application users are transparently directed to the closest cache instance. Invalidation messages sent to the central cache instance (where the applicaton is hosted) are automatically propagated to remote cache instances.
