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.
Cloud server hosting offers the advantages of increased accessibility and reliability, seamless scalability and potential cost savings, as customers are freed from having to invest in on-premises servers and hardware, and they pay only for the resources they consume. On the other hand, security and lack of access and full control are potential concerns with cloud server hosting.
