Cloud hosting services are services provided on virtual servers to websites from which they derive computing resources from the physical web servers underlying the networks. It follows the utility model of public service available as a service to a product and is comparable to gas and electricity, the traditional utilities. Customers can access these services based on website requests and can pay for what they use.
Cloud hosting has extensive server networks, primarily in different data centers. Practical examples of cloud hosting are classified in the Platform-as-a-Service (PaaS) and Infrastructure-as-a-Service (Iaas) classifications.
In IaaS offers, the customer is offered a virtualized hardware resource that allows them to install the required software environment before creating a Web application. However, on a PaaS service, the customer has a software environment on which he can directly install and develop his Web application. However, businesses with complex, experienced IT professionals and infrastructure can opt for a more customizable IaaS model, but will generally prefer the simple PaaS option.
Cloud hosting involves the use of public cloud templates that ensure the security of your data and are sufficient for the website’s facilities. Conversely, businesses can turn to the cloud if privacy and security are your primary concern because they use an isolated site on their resources.
Typical cloud hosting has the following advantages, namely:
· Reliability. It is not hosted on a single physical server; instead, the website is on a virtual partition to pull resources from a large underlying network of physical servers for its disk space. If a server is offline, the level of resources that can be obtained in the cloud may be very rare, but will have no effect on the website whose server is looking for the resources of the remaining server network. In fact, cloud computing platforms survive and ensure the continuity of the data center as a whole, by pooling cloud resources from various data centers in different locations.
· Physical security. The underlying physical servers are hosted in data centers and thus benefit from the security measures implemented by the facilities to protect people from disruption or on-site access.
· Flexibility and scalability. The resource is available on demand in real time and is not limited to the physical capacity or constraints of the server. In the event that a client site requests additional resources from the hosting platform due to visitor traffic or the implementation of new features, access to the resource is transparent. Using a private cloud model means that the service is allowed to burst, so resources are publicly available for nonsensitive processing in the event of increased on-site activity.
The most visible benefit of cloud hosting is that the customer pays only for the use they actually use and that the resource is available at all times, even if there is no shortage of unused capacity . Load balancing is based on the software. It is therefore possible to adapt it instantly to changes in demand.
