Why ‘cloud computing’ is called ‘cloud computing’
by MATT WEINBERGER

Rewind to the early nineties: Computer scientists and engineers needed some way in their diagrams and slideshows to refer to “the network,” that big grouping of computers and storage devices out there somewhere. In other words, they needed some way to refer to something that was, essentially, somebody else’s problem.

They settled on a cloud.

You can see one of the earliest uses of that idea in this diagram from US Patent 5,485,455, “Network having secure fast packet switching and guaranteed quality of service,” filed in the January of 1994.

If you squint, that “Network” bubble is cloud-like. The patent’s authors just meant to illustrate that what was in the network wasn’t important for their purposes.

By the time US Patent 5,790,548, “Universal access multimedia data network,” was filed for in the April of 1996, the cloud looked a lot more like a cloud:

It’s just meant to be a vague description of things happening elsewhere.

This usage led to the growing popularity of the term “cloud computing” to refer to servers, networks, and data centers that were located or managed elsewhere and thusly someone else’s problem. A Compaq document from 1996 was probably the first time the term was used in any kind of official capacity, reports the Technology Review. But the term really caught on when Amazon Web Services launched its Elastic Compute Cloud (EC2) in 2006.

Amazon EC2 basically sells virtual servers to other companies — the very definition of “somebody else’s problem.” Other companies caught on and started offering software (like Salesforce), storage (like Box), or a mix of the two (like Microsoft Office 365) from their own data centers to companies who don’t really care where it comes from. To them, the cloud providers are their own squiggly lines on a diagram.
