CLOUD COMPUTING. This is the practice of using a network of remote servers hosted on the internet to store, manage and process data, rather than a local server or a personal computer. Cloud computing allows us to store personal files, even backup our entire hard disk drive on servers over the Internet. Cloud computing is possible because of data centers. A data center is a facility used to house computer system and associated components. A data centre may be a room or a large organization. Since data centres are expensive to build and maintain, only large organizations are able to afford and maintain. Small organizations which cannot afford their private data centers lease server and storage services from large data center organizations in the cloud. There are four primary types of clouds namely: Public clouds Private clouds Hybrid clouds Custom clouds
