I began the process of updating and clarifying the first paragraphs of these articles. Improvements welcome.
Cloud computing makes computer system resources, especially storage and computing power, available on demand 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.
Edge computing brings memory and computing power closer to the location where it is needed. Definitions vary.
