What is Cloud Computing?

We get asked a lot to explain just what exactly Cloud Computing is, so we have written a simple guide.

The Traditional IT Model

Before we start thinking of the cloud as some magical mystery, we need to look at an example of an IT systems your company is using.

For our example, lets use email.
So, let’s say you are a small company with approximately 500 employees and you have a server located in your company HQ which runs your email using Microsoft Exchange. In this scenario, you have a server which you have designed, implemented, and now you ‘feed and water’; i.e. you maintain this server at your company premises, you provide it power, you manage the operating system and the patching, you manage the Exchange application and its patches, and you also provide this server with network connectivity to your local network (LAN).

The Cloud IT Model

So what does this look like when you move email to the cloud?

Our example continues, and your small company decides to move your email to the cloud. Microsoft offer Exchange Online as their cloud email solution. You can purchase this on its own, or as part of the Office 365 package, but essentially you are still purchasing the same thing.

Microsoft’s cloud solution, means that they run and manage a vast array Exchange servers for a variety of customers in one of their datacentres, and sell access to those services to individual companies. They achieve this using economies of scale, and selling multiple customers email accounts spread across their pool of servers.

What they are selling you is an array of hosted email accounts with a specific Service Level Agreement (SLA) for a small monthly fee, which generally is slightly cheaper than your company can provide the same service.


So outsourcing your services to the cloud sounds ideal doesn’t it? Someone takes a service you are already running and then charges you less to run it elsewhere, taking away the headache of managing the infrastructure. In a nutshell, that is why the cloud is such a big deal right now, as it opens the doors for small to medium sized companies to deploy enterprise applications for a fraction of the cost.

It really is that simple, although, you do need to remember that your services are still being run on someone’s infrastructure, and those services still need to be administered.
