Pros: Enterprisewide or infrequently used data is centrally managed, and application- or site-specific traffic stays local.

Cons: Highly susceptible to network outages, so it requires redundant WAN links or data replication schemes.

Best For: Applications that use replication as an integral design feature, such as daily batch transfers; applications that rely heavily on computational power; and graphics, distributed directories and batch-oriented applications.
