What is Cloud Hosting Service | How It Works

Cloud hosting is the purchase of computing resources from a cloud service provider or reseller to host data, services and/or applications. It is an Infrastructure as a Service (IaaS) cloud delivery service pack that provides a bundle of virtual servers which you can access remotely through the Internet.

Cloud Hosting Services

Cloud hosting provides customers direct access to multiple interconnected servers in the cloud. Before now, a single server provides such services. This is not the case with cloud hosting. In other words, the cloud service provider’s virtual servers which pull their computing resource from extensive underlying networks of physical web servers provide the cloud hosting services.

Key Features/Benefits of Cloud Hosting

While lack of full control of data and security are the most frequently cited concerns with cloud hosting, there are many benefits of cloud hosting.

Firstly, clients can tap into cloud hosting services as much as they need to, depending on their requirements at any stage. This can result in cost savings as they only have to pay for what they use, and because they can access it at any time, they don’t need to pay for additional capacity. This is why we sometimes refer to cloud hosting as server on-demand hosting, cloud server hosting or cluster server hosting.

Secondly, let’s have a look at other key features and benefits of cloud hosting. They include:

Scalability:
This refers to the ability of the cloud infrastructure to auto-scale either up or down depending on traffic patterns. The resource is available in real time on demand and not limited to the physical constraints/capacity of one server. If a client’s website, for instance, demands the extra resource from its hosting platform due to a spike in visitor traffic or the implementation of new functionality, the resource is accessed seamlessly.

Security:

Data centers use physical servers to provide hosting services. As a result, the client’s data are secure because they benefit from the security measures that those facilities implement to prevent people from accessing or disrupting them on premise.

Reliability:
The services are highly available because rather than being hosted on one single instance of a physical server, hosting is delivered on a virtual server partition. The virtual server partition draws its resource, such as disk space, from an extensive network of underlying physical servers. For example, if one server goes down it will have no effect on availability, as the virtual servers will continue to pull a resource from the remaining network of servers.

Responsive load balancing:
Load balancing is software based and can, therefore, be instantly scalable to respond to changing demands.

How Cloud Hosting Works

Cloud hosting is usually implemented using two cloud models, namely:

Public Cloud

Majority of cloud hosting approach involves the use of public cloud models. This is hosting on virtual servers that pull a resource from a pool of other publicly available virtual servers. It uses the same public networks to transmit data. The data is physically stored on the underlying shared servers to form the cloud resource. Public clouds include some security measure to ensure that data is kept private.

Private Cloud

Private clouds are more suitable where security and privacy are more of a concern.
They use ring-fenced resources, such as servers and networks, whether located on-premise or with the cloud provider.

Type of Cloud Hosting Services

A cloud hosting service provider offers two main types of service to clients. They include:

Infrastructure as a Service (IaaS)
This type of service offers clients virtualized hardware resource on which they can install any software environment of their choice before building their own applications. It is more customizable, and therefore appropriate for businesses with complex IT infrastructure. It is also suitable for experienced IT experts and developers.

Platform as a Service (PaaS).
This service type provides clients with the software environment, on which they can go straight to installing and developing their own applications. It is a more preferred service to IaaS option because people who are less technically proficient can easily use it.
