Answer
Cloud computing is the technology that allows users to get access to
computer system resources, especially data storage and computing power,
without direct active management by the user. The term is generally used
to describe data centers available to many users over the Internet. Something
called Large clouds, which are widespread today, often have functions distributed
over multiple locations from central servers. If the connection to the user is
relatively close, it may be designated an edge server.
Potentially, everything from generic word processing software to customized
computer programs designed for a specific company could work on a cloud
computing system. One of the main reasons someone might want to rely on
this technology is the ability to access applications and data from anywhere
at any time, using any computer linked to the Internet. Another important
reason is the fact that it would reduce the need for advanced and expensive
hardware on the client side.
Some of the main disadvantages are the risk of failure, loss of data,
security and privacy-related issues, vulnerability to attacks and limited
control and flexibility.
