The essence of the cloud hosting services lies in the fact that the client uses and pay for, only that much infrastructure that he uses and access the service from anyplace using a browser or API. Virtualization and distributed computing lies at the core of the cloud services. Virtualization ensures that the client can get unlimited scalability of the IT resources at a short notice and hence the end user is least concerned with the provisioning and upfront investment risks.

Distributed nature of the cloud computing architecture implies that the servers are located at the closest point of the internet cloud thereby enhancing the responsiveness of the network and which acts more like a local network in uptime and reliability.
