What is Cloud Computing?

Cloud computing is the on-demand usage of computing resources or applications which are made available through an online platform.

Examples of commonly used resources include storage (e.g. file sharing) and access to business applications (e.g. email), but the full list of uses is expansive. Where a growing business might outgrow hardware in a bare metal dedicated server, the flexibility and scalability of a cloud hosting solution means that it is usually easier and more cost-effective to cope with increasing demand.

The easiest way to break down cloud hosting is to compare it to hosting your website on a single server model. With traditional hosting, you have a single server that contains all of your website’s files. When a user visits your website these files are then served up from that single physical server. But with a cloud hosting setup, your site’s resources can be drawn from multiple different virtual server environments.

At the core of a cloud hosting setup is a network of physical servers, with virtualised servers running on top of them. This allows your solution to accommodate a number of different applications and projects, such as websites, databases, email, development and testing etc., as you're effectively splitting your server up into smaller functional parts. Compute can also be split into discreet packages called virtual machines (VMs), making setups such as public cloud hosting possible - where more than one user is able to make use of a single server's compute. Storage and network can also be shared.

Advantages of cloud

No CapEx

Cloud hosting eliminates the need for hefty upfront investment in hardware and software, and makes financial predictions simpler with the fixed monthly cost. Not to mention the setting up and running of your own on-site data centre, with racks of servers, power, cooling systems and the expertise needed to manage it.


Cloud computing lets you have an elastic business model, delivering the right amount of IT resources for each stage of your business’ growth. Great for any business with big plans for the future or if your website experiences large fluctuations in user traffic, as you won’t be limited by your own in-house server capacity or network.


Most cloud services are controlled by the user. So, vast amounts of computing resources can be provisioned in minutes, often at the touch of a button. This makes for quick deployment of resources, meaning you waste less time on setting up new applications and can spend more time on developing your enterprise.

Data backups, disaster recovery and business continuity are much easier to achieve, and less expensive, with cloud than with an on-premise solution. Through techniques such as load balancing, your data can be mirrored across more than one data centre, meaning that if the first data centre was offline for any reason, your solution would still be available.
