Cloud server hosting is when hosting services are made available to customers on demand via the Internet. Rather than being provided by a single server or virtual server, cloud server hosting services are provided by multiple connected servers that comprise a cloud. Cloud server hosting is also sometimes referred to as cluster server hosting or server on-demand hosting.
You get to benefit from an economy of scale, meaning you sharing hardware with other businesses but only pay for the amount of compute and storage capacity that you use. If you need to increase your usage, you can do so through a dashboard. You have unlimited flexibility to increase or decrease your resources and can change server specifications with the demands of your business.

A Cloud VPS is to all effects a virtual server that is activated within Aruba's Cloud infrastructure. Cloud VPS is an incredibly convenient solution that lets you activate one or more servers in just a few easy steps. You can choose from 4 sizes and many templates and preconfigured operating systems that are all ready to use. The Windows Server license is included in the price of the server.
The common pricing model in cloud hosting is to pay as you go without large upfront costs. Be wary of any plan or hosting company that seems to buck this trend. Inquire about the security of the datacenters that house the servers. One study found that one third of data breaches involved some compromise of physical security. The decentralized nature of cloud hosting makes data security more complicated. Be sure that the network you will be using is compliant with regulations such as PCI DSS and HIPAA. Look for third-party audits to confirm this.
Rather than being hosted on one single instances of a physical server, hosting is delivered on a virtual partition which draws its resource, such as disk space, from an extensive network of underlying physical servers. If one server goes offline it will have no effect on availability, as the virtual servers will continue to pull resource from the remaining network of servers.
