Cloud hosting service is those virtual servers that use the physical web servers to pull the computing resources required for their clients. It is an alternative to hosting websites on either dedicated or shared server hosting service. The examples of cloud hosting fall under either a) Infrastructure as a Service (IaaS) and b) Platform as a Service (PaaS) classifications.
PaaS – In this hosting service, the client can go directly to installing and develop their web application through software environment provided to them. It is easier to use compared to IaaS. Clients who are less technically proficient can use PaaS.
IaaS – In this, the client is provided only with the virtual hardware resources. It is more customized and is appropriate for businesses with more complex IT infrastructure. Thus, the more experienced IT professional the more useful is the IaaS.
Features and Benefits of Cloud Hosting –
- Reliable – Cloud hosting is reliable source as it is delivered on the virtual partition which is able to draw its resources, namely, disk space, from an extensive network of underlying physical web servers. If any server goes offline, it will not affect the availability of the cloud-hosted server, a virtual server will continue to pull-out resources from the remaining network of web servers.
- Physical Security – The physical servers are housed and set up within the data centers and thus there is a benefit from the security point of view.
- Scalability – The resources are available in real time and on demand and is not limited to any physical constraint of any server.
- Utility Style Costing – The payment made by the client is only done for the service they use. The resources available are for spikes in demand, however, there is no wastage capacity which is unused when the demand is lower.
- Responsive Load Balancing – The balancing of the load is software based and thus can be scaled up to respond which depends on the changing demands.
