As you know cloud hosting is just a small part of the internet. In cloud hosting, all the resources that are needed to maintain your website are spread across more than one server. Each of these servers help to perform some specified task. If there is ever a failure at one of the servers, another server will get in place as a
backup services to give the required results.
Cloud hosting has three categories based on how it works. Software as a Service or SaaS is a service where the
hosting company manages all the registered software applications. In Platform as a Service (PaaS), the host manages the working platforms of cloud server for the development and operation of business applications. Infrastructure as a Service (IaaS) is considered as an improved version of web hosting where
virtual servers and other required equipment are bought if needed.
