Cloud computing

Cloud computing delivers computing services such as servers, databases, networking, and software over the Internet.

Providers of cloud computing have built many large data centres around the world, equipped with banks of networked computers. They have developed technology to give customers access via the Internet to buy and use capacity as needed, usually on a ‘pay-per-use’ basis.

To access cloud-based systems, all that is needed is a PC or phone and an Internet connection, so businesses can reduce investments in servers and other IT equipment.
