In general, cloud computing services that include Web hosting can be an alternative to other traditional kinds of Web hosting that are not based on cloud computing principles. One of the biggest differences could be called a "single client" versus "multi-tenant" approach. Cloud computing services that include Web hosting are usually multi-tenant. That means that the files and data resources of multiple clients are housed on the same server. This provides flexibility and on-demand services for individual clients, so that providers can scale up or scale down delivery easily.
By contrast, dedicated Web hosting will involve a Web hosting company serving only one client on any given server. This provides more individual security and a more focused approach to serving an individual customer.
