Demystifying cloud computing

Cloud computing is a technology that uses the internet and remote servers to maintain data and applications. They allow users to use applications without installation and access personal files at any computer with internet access. Take the example of email, which can be accessed from any computer worldwide, and all one needs is the internet. The global cloud computing market is estimated to be worth $241 billion by 2020 compared with $40.7 billion in 2010.
