Cloud hosting are services used for providing website hosting on virtual servers like Shopify, that get their computing resource from complex underlying physical web server networks. It takes up the utility version of computing where its availability is in service form instead of product form, therefore, compared to conventional utilities like gas and electricity. Widely speaking, the customer can tap into the service as often as they feel like depending on his website demands and pay for only what they use.
These services exist as an improved alternative to web hosting on single serves which are either shared or dedicated. Therefore, it is safe to consider them as extensions of the main model of clustered hosting that had websites hosted on numerous servers. However with cloud hosting, the server networks used are many and usually extended from various data centers within various locations.
Two classification of cloud hosting;
- Infrastructure as a Service, IaaS, where they simply provide customers with virtualized hardware resources. They can install their own software of choice on these hardware resources before creating a web application.
- Platform as a Service, PaaS, provides customers with software of their choice similar to IaaS cloud hosting. However, as opposed to IaaS where they install the a software for a single task, PaaS provides a solution stack such as database support, operating system, programming support, and web server software. With the solutions, time is saved that would have been spent on installing different software for different function, hence one needs to install it and start developing their websites.
The Virtual Data Center, VDC, provides the cloud hosting development concept. It uses a virtualized server networks in the cloud that can be used for hosting all forms of business IT operations with the inclusion of websites.
The most used cloud hosting examples involves using public cloud models. Here one needs host on virtual servers that pull resources from one pool used by other public virtual servers using the same networks for transmitting data. The data is physically stored within the underlying servers forming the cloud resource. Public clouds include security measures that ensure data remains private and would be adequate for several website installations. However, in cases where privacy and security are a top concern, enterprises can choose to move to private cloud hosting where the clouds use ring-fenced servers and networks found with a cloud provider or on site.
