A cloud server is a shared section of a server. It’s allocated for your use (via a virtual environment) and controlled by the service or cloud provider. On your end, it appears that you are running your own compute and storage space. However—and this is an important point—there are usually a large number of other people using the same compute and storage resources within their own virtualized environment.
Because cloud hosting relies on a multitude of virtualized servers, the service allows for more flexibility when selecting the operating system or other software to install and configure. Pervasive Unix-based operating systems, including the CentOS, Debian, and Fedora Linux distributions, are twice as popular as servers configured with Windows. With so many options to choose from, here’s our top pick for hosting Linux in the cloud:

Definition: Cloud servers utilize multiple servers connected together in a cluster which is backed by SAN storage. Customers utilizing a cloud platform will benefit from the multiple servers because they will receive unlimited storage, maximum bandwidth, managed load balancing and no ties to a specific piece of hardware. The basic difference between public and private clouds are in public, the cluster is multi-tenant and a private is a single client.
Cloud hosting sometimes gets confused with a virtual private server, or VPS. Both configurations rely on the virtualization of physical server resources. Although a cloud server can be called a VPS, a VPS is not a cloud server. One of the key differences, aside from the infrastructure configurations, is the payment model — the automation and vast network associated with cloud hosting enables providers to offer cheaper, pay-as-you-go solutions that can be scaled up or down at a moment’s notice.
