What is cloud computing?

Cloud computing is a phrase used to describe a variety of computing concepts that involve a large number of computers connected through a real-time communication network such as the Internet.[1] In science, cloud computing is a synonym for distributed computing over a network, and means the ability to run a program or application on many connected computers at the same time.

Why it is called cloud?

The phrase also more commonly refers to network-based services, which appear to be provided by real server hardware, and are in fact served up by virtual hardware, simulated by software running on one or more real machines. Such virtual servers do not physically exist and can therefore be moved around and scaled up (or down) on the fly without affecting the end user – arguably, rather like a cloud.

What are it’s advantages?

Following are some advantages of cloud computing:

  1. Decreased Costs
  2. Scalability and Speed
  3. Innovation
  4. Convenience
  5. Location Independence
  6. Optimal Resource Utilization
  7. Flexibility
  8. Device Independence
