Click here for a brief summary of a Northern Virginia community's
surrender to the Cloud's requirements by selling their houses and farms
so that massive server farm can be built.
Rich Miller's now-ancient Data Center Frontier survey
of 2015's top ten cloud server farms has the advantage of providing
statistics for their then-current and projected size, and more
importantly, their power consumption and cooling requirements.
Photographs of the interior of some data centers show a clear
distinction between the blue "cooled" aisles where the memory and
computing resides, and the red "hot" aisles which draw off the
otherwise fatal heat generated by their electricity demands which can
reach 1500 watts per square foot in spaces that extend for acres.
For example, the NSA's Bluffdale, Utah computing center, which was the
seventh largest in 2015, was said to have computing and storage
capacity to draw up to 65 megawatts (ca. 26,000-56,000 average homes
per year), requiring at peak load up to 1.7 million gallons of water
per day to keep it from malfunctioning and harming operators. By
2021, it was reported to be capable of yottabyte information storage
and processing (Gillis). Old
server farms were designed to be air-cooled, but increasing their size
and squeezing together more microprocessors and memory units per square
foot required more efficient water chillers to cool the air. By
2022, Data Center Frontier
was reporting that fully immersive cooling, direct submersion of the
computing elements in non-conducting coolants, was a major new
technological change. Heat from the coolant can be harvested and
used to create power, reducing the unit's carbon footprint by some
amount. (In a 1/20/22 letter to the Washington Post, an
inhabitant of the Prince William neighborhood pointed out that they are
required to use wells for their drinking water, so the projected server
farms will be competing with their wells for its cooling water, though
that probably won't last long.)
By August, 2020, TeleGeography reported that Asia was home to the largets number of the Cloud's server farms. To see a map of the world's physical Cloud locations, go to: https://www.cloudinfrastructuremap.com/
Information
also is transported by submarine cables, which are not as susceptible
to damage or disruption as satellites. To see TeleGeography's

James Yoder (an incoming freshman [!]
at UT Austin), has created an interactive satellite map called "Things in Space" on Github: https://ajmas.github.io/ThingsInSpace/
.
Of course, not all of these satellites transmit digital text, but the
entire system is crucial to our current Internet structure, down to
your access to ebooks in the Goucher Library's collection or your
social media accounts. Roll over "Help" and "About" in the upper
right corner for some
very brief clarification of what you are seeing. Obviously
most of the "stuff in space" is not related to the Internet
and Cloud, but just running over an individual dot will
show its orbit and identify it as an actual satellite, spent rocket
component, or other type of object. (Red dots are actual
satellites, blue dots labeled "R/B" are spent rocket bodies, and grey
dots labeled "DEB" are debris. Satellites labeled "COSMOS" are
Soviet or Russian in origin and mostly military. Starlink
comprises an ever increasing fraction of all orbiting material.)
Scrolling in or out with the + and - buttons on lower right gives you a
view of the various layers of our orbital "family" and you can
click-drag up or down to see Earth from the North or South pole.
From a polar view, the large ring you can detect in an upper orbit is
composed of
geostationary satellites, a highly competitive orbital slot.
To
track individual orbital objects, including the International Space
Station (for which I can conceive of no application for a 341 paper),

Additional articles if you are really into this topic!:
Alexander Gillis, "Yottabyte (YB)," TechTarget, updated 9/20/21.
Note this article is now years old and its information, other than the
basic facts about prefixes and their numerical meaning, are suspect.
Especially consider the assertion, in September 2021, that "Currently,
there is nothing that can be measured on a yottabyte scale." In that
same year (see above) Gillis was reporting that the NSA's Bluffdale,
Utah server farm was estimated to have yottabyte capacity.
Julie Kendrick, "The 10 Largest Server Farms Ever Built," History-Computer.com, 26 July 2023:
This article measures server farm size by the millions of square feet
of horizontal space they enclose. Other relevant measures might
be computing power, electrical consumption in megawatts, and cooling
water requirements. Rich Miller's 2015 article (below) was more
helpful in providing some of those comparative data. Note
especially, though, that Kendrick's #1 biggest server farm in 2023,
"The Citadel" in Tahoe Reno, Nevada, is said to be powered entirely by
renewable energy sources, for both computing electricity and cooling
capacity. Also note that Miller's top 10 were predominantly in
Northern Virginia, especially Loudon County, whereas Kendrick's include
installations in Europe and China. What does that tell us about
how the material infrastructure reflects the "nationality" of the
Internet?
Rich Miller, "The Top 10 Cloud Campuses," Data Center Frontier, 23 November 2015. https://datacenterfrontier.com/top-10-cloud-campuses/
Miller's list inludes many photographs of the interiors of cloud server
units, and some of their cooling devices, a useful addition to
Kendrick's article (above). Note that Miller's #1 largest cener,
Switch SUPERNAP in Las Vegas, took up 1.4 million square feet, whereas
Kendrick's, eight years later, is "The Citadel" in Nevada at 7.2
million square feet. Try finding comparative land forms you are
familiar with to get some idea of how big these installations are, and
are becoming.
