3 Enterprise Branch Wide Area Application Services Design Guide (Version 1.1) OL-12945-01 Introduction Appendix D—Additional References 69 Introduction As enterprise businesses extend their size and reach to remote locations, guaranteeing application delivery to end users becomes increasingly important. In the past, remote locations contained their own application file servers and could provide LAN access to data and applications within the remote location or branch. Although this solution guarantees application performance and availability, it also means more devices to manage, increased total cost of ownership, regulatory compliance for data archival, and lack of anywhere, anytime application access. Placing application networking servers
