Being the latest kind of hosting, cloud hosting has become very popular in just a few years. Its main concept is “Divide and Rule” as the required resources used to maintain your website are widely spread across several servers rendered to satisfy your needs.
In the case of a server malfunction, the fact that cloud hosting uses more than one server reduces any chances of downtimes. It allows you to easily handle peak loads without facing bandwidth problems as another server will be handling any addition resources. Therefore, your website does not just rely on one server, but a cluster of them that work together, hence the term “cloud”.
In some way, cloud servers work much like physical servers; however, their functions are very different. When opting to use cloud hosting, clients usually rent the space in a virtual server instead of purchasing or renting physical servers. They are routinely rented by the hour depending on the required capacity at any specific time.
A good example of cloud hosting is Google, the king of search engines. Its resources are spread all over hundreds of cloud servers, which is why you will ever see Google.com going through downtime problems at any time.
How it Works
Each server helps carry out a specific set of tasks. In case there is a failure with any of the cloud servers, another server, or set of servers, will temporarily kick-in as a back up to provide the resources required. However, the use of poor quality server hardware can greatly deter the performance. This kind of implementations are a form of cheap hosting and are not worthy of getting tagged with the cloud.
When providing enterprise level of hosting, quality has to be the prime focus. Therefore, high quality enterprise cloud hosting providers make good use of VMwareto deliver very reliable cloud services that are better than physical dedicated servers.
Benefits of Cloud Hosting
There are many benefits of cloud hosting compared to conventional methods of hosting. For starters, clients receive the best of both worlds in the sense that resources are either scaled up or down making it flexible and more cost effective.
Secondly, in case there is an increased demand on the servers, the capacity can automatically increase to match the demand without having to pay for a permanent basis.
Also, cloud servers run on hypervisors which control operating system capacity, thus allocated where required.
Finally, its ability to provide more redundancy where other servers take the place of one that fails makes cloud hosting very reliable.
