Advances in virtualization and distributed computing have allowed
corporate network and datacenter administrators to effectively
become service providers that meet the needs of their "customers"
within the corporation.

Ahybrid cloudenvironment consisting of multiple internal and/or
external providers"will be typical for most enterprises".By
integrating multiple cloud services users may be able to ease the

compliance.
Another perspective on deploying a web application in the cloud is
using Hybrid Web Hosting, where the hosting infrastructure is a mix
betweenCloud Hostingfor the web server, andManaged dedicated
