A cloud can either be a public cloud or private cloud. A public cloud is a set-up where the services are offered on customer demands. Whereas in a private cloud type of service only a single customer owns the entire cloud similar to a dedicated hosting server. When both these Cloud types are used in combination, it is known as the hybrid cloud. In a hybrid cloud a private cloud is hosted in a public environment.

Generally, the cloud computing has a front-end where the clients can log-in and perform tasks in the back-end which is hosted by the cloud hosting provider. The front-end covers the customer computers and the applications essential for accessing the cloud. Internet is the medium used to communicate between the two.

Cloud Server Hosting

Below is an elaboration of the different types of Cloud hosting services.

Types of Cloud services:

  • Infrastructure as a service (IaaS): As the name itself suggests, in this type of service offering, the Infrastructure is provided as a service. Here the customers application interface access the virtual servers and storage hosted by the provider.
  • Platform as a service (PaaS): Platform within the cloud/ shared cloud is a set of applications or software’s that operates on the platform that is hosted in the cloud. The customers can run the applications in the platforms hosted by the cloud hosting provider through the platform or Application Program Interface (API).
  • Software as a service (SaaS): In software as a service model, both hardware as well as software infrastructure is offered for usage to customers.
  • Hybrid cloud: A hybrid cloud is a cloud computing environment in which an organization provides and manages some resources in-house and has others provided externally. For example, an organization might use a public cloud service, for accessing data but still continue with its maintenance in-house storage for operational customer data. Ideally, the hybrid approach allows a business to take advantage of the scalability and cost-effectiveness that a public cloud computing environment offers without exposing mission-critical applications and data to third-party vulnerabilities.
