Cloud Hosting – The Way Forward

Due to the scalability and improved security and data privacy, more businesses need to realize what cloud computing can do to improve their current IT property.

Cloud hosting is a service providing hosting for websites on virtual servers which pull their computing resource from extensive underlying networks of physical web servers. Simply put, the client can utilise as much of their service as they need, depending on the demands of their website, paying only for what they use.

Cloud hosting is an alternative to hosting websites on single servers (either dedicated or shared) and as such this can be considered as an extension of the concept of clustered hosting where websites are traditionally hosted on multiple servers. However, with cloud hosting the network of servers that are used is vast and is more often than not, pulled from data centres in several different locations.

Cloud hosting offers the following features and benefits:

Reliable – Since rather than being hosted on a single instance of a physical server a website is hosted on a virtual partition which draws its resources, ie disk space, from an extensive network of underlying physical servers. If one of these servers should go offline, it will then dilute the level of resource available to the cloud somewhat but won’t have any effect on the availability of the website whose virtual server will continue to pull resources from the other network of servers. Some cloud platforms can even survive an entire data centre going offline since the pooled cloud resource is drawn from multiple data centres in varying locations to spread out the risk.

Scalability and Flexibility – As the resources are available in real time as needed and are not limited to physical constraints or capacity of 1 server. If a particular website has a need for extra resource from the hosting platform because of a spike in visitor traffic (a sale etc) or perhaps they may have increased the requirements due to the addition of new functionality, the resource can be accessed seamlessly.

Physical Security – the underlying physical servers, being housed within data centers will benefit from security measures implemented by those facilities which will in turn prevent people from accessing or interfering with them on the site

Pay as You Go – You only pay for what is actually used. The facility is there for spikes in demand but there is no wasted capacity remaining unused when your demand is lower.
