Bandwidth — Organizations often attempt to improve application performance by making costly investments in more bandwidth. While additional bandwidth may reduce
network congestion, no amount of bandwidth can address performance issues caused by high latency and application and network protocol chattiness; and

IT infrastructure resources — Deploying additional IT infrastructure resources at remote locations can increase selected application and data services
performance. However, this approach is expensive, complex to manage and increases the risks of data inconsistency and compromised security.

Caching — Cache-based architectures are application specific, and accordingly only improve the performance of applications for which they are written. For
example, wide area file services (WAFS) approaches only address poor performance of file-based applications. Caches store frequently accessed data objects (files, web pages or attachments) locally at remote locations and replicate and synchronize
that data with servers, but this approach has limitations. For instance, when an end-user changes and renames a data object, caches no longer recognize that this data object has moved across the network and cannot optimize its transfer. In addition,
caching approaches have inflexible architectures with limited ability to extend to other applications and also increase the risk of data inconsistency; and
