In simple terms, cloud computing is the delivery of computer services like servers, storage, databases, networking, software, analytics and more—over the Internet a.k.a. ‘the cloud’. Any company that provides these computing services are called cloud providers. They charge the companies based on usage, similar to how you are billed for electricity at home.
You are probably using cloud computing right now but may not be aware about it. If you use an online service to send emails, watch movies or TV shows, listen to music, play games and more, it is the cloud computing that is making it possible for you to do so.
