Cloud computing is the on-demand availability of computer system resources, especially data storage (cloud 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. Large clouds, predominant 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.
Types of Cloud Services
Regardless of the kind of service, cloud computing services provide users with a series of functions including:
. Storage, backup, and data retrieval
. Analyzing data
. Delivering software on demand
