Cloud computing is based on the idea that, rather than each company or individual being set up with their own computing devices for data storage and manipulation, computing resources can be pooled and shared via the Internet. You might first think of companies such as Amazon, Google, Facebook and Twitter.
The goal of cloud computing is therefore a shared IT infrastructure providing easy access to (powerful) computer resources which are geared towards users' needs – they can be expanded or scaled down as the user requires.
Benefits of Cloud Computing:
Cloud computing has three main subtypes:
- Apublic cloud, in which a service provider makes computing resources available to the general public over the Internet,
- A private cloud solely for a given organization , the private cloud from a vendors perspective is essentially a market for licensed tools, hosting and consulting.
- A Hybrid Cloud, this cloud is a combination of private and public clouds that remain unique but are bound together by technology that enables data and application portability, combining providers and consumers from both private and public clouds, and may have many service levels.
