What is Cloud Hosting?

Cloud Hosting is based on the principles of Cloud Computing.

Cloud Computing is the delivery of computing as a service rather than a product, where shared resources, software, and information are provided to computers and other devices as a utility (such as the electricity supply to your home or to where you work) over a network (typically the Internet).

Cloud Hosting focuses on keeping your website up and running and handling the peaks in usage easily. This is achieved by spreading the resources required for your website among many physical servers thus reducing the reliance on any single piece of computing hardware. 

With Cloud Hosting you can say goodbye to the old idea of renting a server or shared server space. Cloud Hosting provides us with server clustering. Instead of using the power of one server, you have access to the power of many; linked together through visualization.

We have all seen the situations where a website might be under stress because it has had a sudden burst of popularity. With regular shared hosting once that website reaches the limits of the single server, it is on, it chokes. With Cloud Hosting the website would have access to multiple different servers and so have access to as much bandwidth, RAM, CPU power or any other server side resource that it needed.

Cloud Hosting provides computing power, on demand, when you need it. If you no longer need so much power, you can easily release the resources back into the “Cloud” so that they can be used by others.

How does Cloud Hosting work?

A significant number of individual servers are teamed together to create a ‘Cloud’. This has many advantages – it balances overall load between the servers, massively reduces the reliance on individual physical servers for service provision and provides flexibility to deploy resources as required.

Individual virtual machines are then deployed into the cloud, each with their own resource allocations such as processor, memory and disk storage. Disk storage in enterprise clouds is provisioned on single highly available SANs (Storage Area Networks).

Software is installed on each physical server called a ‘hypervisor’. This is usually a small piece of code that controls the virtual machines that will run on the physical hardware. The most common hypervisors used are VMware, Xen and Hyper-v.

How does Cloud Hosting compare with other hosting methods?

The traditional way of hosting your website is either with Shared Web Hosting or using a Dedicated Server to host your site.  These have their own merits, but compared to Cloud Hosting they’re looking a bit dated.

Shared Web Hosting: is sharing resources with many other websites on the assumption that not all sites will be resource hungry all of the time. If another site on your server is a hog, your site will suffer – you have no guarantee of the resources when you need them.

Dedicated Server Hosting: you pay for the storage capacity and power of a whole server even if you don’t use it. Some days you may get a spike in traffic, but no matter how much you use, you always pay the full price.  If you exceed the resources of this physical server, you have to buy another server to share the load. More cost.

With Cloud Hosting you benefit from the principles of cloud computing in the following way:

  • Dedicated Resources: All resources allocated to you are yours and yours alone – you don’t share it. If you are allocated xMB of RAM, you will always have xMB.
  • Scalable Resources: When you suddenly need more resources, you don’t need to install new hardware, or add another server, or steal them from someone else sharing your server. Instead you simply allocate more to your website from the cloud.  Since there are many servers interconnected in your cloud, you can provision whatever you need, whenever you need (and of course, whatever you provision is yours and yours alone).
  • Resilient Resources: Imagine if a whole server in the cloud crashes and burns? Your site will still be running because redundancy is built into the cloud computing model – if one “node” on the network of machines fails, the rest will pick up the slack (compare this with either shared or dedicated server hosting above = disaster)


What are the benefits of Cloud Hosting?

Cloud Hosting provides significant advantages to its users. Cloud Hosting scalability and cost efficiency are its main benefits.

As the technology is highly scalable (load balancing, hardware upgrades, etc), website expansion can be done with the minimum of fuss. Think about the hassle of transferring your website from a shared server to a dedicated server; think about server crash when your website experiences a sudden surge – all these problems can be avoided easily by switching to Cloud Hosting.

Cost is another huge benefit when you need a lot of processing power. Cloud Hosting companies charge their users based on the quantity of computing power consumed. It is similar to your electricity and water supply bills – you pay only for what you use. Therefore gone are the days when you need to reserve massive server resources to avoid website crash due to sudden traffic surges.
