This is what a lot of people think of when the term ‘cloud computing’ is used. The cheapest and easiest solution, a public cloud allows you to have almost all IT functions hosted off-site and managed by a third party. All you need in-house is a browser and an internet connection. You will share facilities with many others, providing economies of scale.

Solutions tend to be simple and standard, allowing you to get up and running fast – a popular option for start-ups or small businesses that want to save on IT investment.
