Question 3

What is cloud computing? Explain with an example.

Accepted Answer

The emerging ICT architecture called cloud computing draws on IT resources outside of the corporation's own data centers or local desktops. With an Internet connection, employees can access virtual servers, storage space, video streaming, specialized software, and other cloud-based services from any location, using many different devices. The services are not in a cloud. The physical hardware that supports them is located in very large data centers operated by Amazon, eBay, Google, and other providers. Google, for example, cuts hardware costs to the bone by building its own servers from inexpensive parts, and distributing the applications over a large number of them. They share the load, and if one goes down, another just takes over.
