What Is Cloud Computing and What Are Public, Private and Hybrid Clouds?

Cloud computing is considered to be the next big computer trend revolutionising the way existing IT infrastructure is run and developed within companies. But what is it? If you type the term into a search engine there will be a whole host of websites that attempt to answer the question but you will often see that many different definitions come back as everyone seems to have a singular take on what cloud computing means to them and their businesses.

Fundamentally, cloud computing is the way that a company will access software, applications, services and data in the future. It is a way that businesses can store and access data through a shared web browser meaning that a company no longer needs physical hardware onsite to store this type of information. The cloud will be provided by a cloud hosting provider meaning a new delivery model for IT services in businesses where the company can gain from economies of scale and virtualised resources. The cloud is an on-demand technology meaning that it can be accessed when required and companies only pay for what is used. It is also a technology that can be accessed from anywhere on a variety of devices including mobile phones; so offering companies greater flexibility and accessibility.
