“Where the Internet Lives” Data Centers As Cloud Infrastructure
C HAPTER 3 “Where the Internet Lives” Data Centers as Cloud Infrastructure JN OEN IFER H LT AND PATRICK VONDERAU mblazoned with the headline “Transparency,” Google released dozens of Einterior and exterior glossy images of their data centers on the company’s website in 2012. Inviting the public to “come inside” and “see where the In- ternet lives,” Google proudly announced they would reveal “what we’re made of— inside and out” by offering virtual tours through photo galleries of the tech- nology, the people, and the places making up their data centers.1 Google’s tours showed the world a glimpse of these structures with a series of photographs showcasing “the physical Internet,” as the site characterized it. The pictures consisted mainly of slick, artful images of buildings, wires, pipes, servers, and dedicated workers who populate the centers. Apple has also put the infrastructure behind its cloud services on display for the digital audience by featuring a host of infographics, statistics, and polished inside views of the company’s “environmentally responsible” data center fa- cilities on its website.2 Facebook, in turn, features extensive photo and news coverage of its global physical infrastructure on dedicated Facebook pages, while Microsoft presents guided video tours of their server farms for free download on its corporate website.3 Even smaller data centers like those owned by Eu- ropean Internet service provider Bahnhof AB, located in Sweden, are increas- ingly on digital exhibit, with their corporate parents offering various images of server racks, cooling and power technology, or even their meeting rooms, Copyright © ${Date}. -
Google's Hyperscale Data Centres and Infrastructure Ecosystem in Europe
GOOGLE’S HYPERSCALE DATA CENTRES AND INFRASTRUCTURE ECOSYSTEM IN EUROPE Economic impact study CLIENT: GOOGLE SEPTEMBER 2019 AUTHORS Dr Bruno Basalisco, Managing economist, Head of Digital Economy service Martin Bo Westh Hansen, Managing economist, Head of Energy & Climate service Tuomas Haanperä, Managing economist Erik Dahlberg, Senior economist Morten May Hansen, Economist Joshua Brown, Analyst Laurids Leo Münier, Analyst 0 Malthe Faber Laursen, Analyst Helge Sigurd Næss-Schmidt, Partner EXECUTIVE SUMMARY Digital transformation is a defining challenge and opportunity for the European economy, provid- ing the means to reinvent and improve how firms, consumers, governments, and citizens interact and do business with each other. European consumers, firms, and society stand to benefit from the resulting innovative products, processes, services, and business models – contributing to EU productivity. To maximise these benefits, it is key that the private and public sector can rely on an advanced and efficient cloud value chain. Considerable literature exists on cloud solutions and their transformative impact across the econ- omy. This report contributes by focusing on the analysis of the cloud value chain, taking Google as a relevant case study. It assesses the economic impact of the Google European hyperscale data cen- tres and related infrastructures which, behind the scenes, underpin online services such as cloud solutions. Thus, the report is an applied analysis of these infrastructure layers “above the cloud” (upstream inputs to deliver cloud solutions) and quantifies Google’s European economic contribu- tion associated with these activities. Double-clicking the cloud Services, such as Google Cloud, are a key example of a set of solutions that can serve a variety of Eu- ropean business needs and thus support economic productivity. -

Distributed Computing Network System, Said to Be "Distributed" When the Computer Programming and the Data to Be Worked on Are Spread out Over More Than One Computer
Praveen Balda et al, International Journal of Computer Science and Mobile Computing, Vol.4 Issue.4, April- 2015, pg. 761-767 Available Online at www.ijcsmc.com International Journal of Computer Science and Mobile Computing A Monthly Journal of Computer Science and Information Technology ISSN 2320–088X IJCSMC, Vol. 4, Issue. 4, April 2015, pg.761 – 767 RESEARCH ARTICLE Security Enhancement in Distributed Networking Praveen Balda, Sh. Matish Garg Distributed Networking is a distributed computing network system, said to be "distributed" when the computer programming and the data to be worked on are spread out over more than one computer. Usually, this is implemented over a network. Prior to the emergence of low-cost desktop computer power, computing was generally centralized to one computer. Although such centers still exist, distribution networking applications and data operate more efficiently over a mix of desktop workstations, local area network servers, regional servers, Web servers, and other servers. One popular trend is client/server computing. This is the principle that a client computer can provide certain capabilities for a user and request others from other computers that provide services for the clients. (The Web's Hypertext Transfer Protocol is an example of this idea.) Enterprises that have grown in scale over the years and those that are continuing to grow are finding it extremely challenging to manage their distributed network in the traditional client/server computing model. The recent developments in the field of cloud computing has opened up new possibilities. Cloud-based networking vendors have started to sprout offering solutions for enterprise distributed networking needs. -

An Interview With
An Interview with WARREN PRINCE OH 413 Conducted by Jeffrey R. Yost on 4 April 2012 Computer Services Project Sunnyvale, California Charles Babbage Institute Center for the History of Information Technology University of Minnesota, Minneapolis Copyright, Charles Babbage Institute Warren Prince Interview 4 April 2012 Oral History 413 Abstract Warren Prince was an executive at Tymshare and served as the leader of TYMNET. He served on the management team at McDonnell Douglas after it acquired TYMNET. The interview concentrates on TYMNET’s history and explaining and providing context to some of the documents he provided for the interview. 2 Prince: So will you produce the chapter in your book out of audio? I’ve got a bunch of papers that might be of interest or might not. Yost: Terrific, I would. Prince: Because it kind of shows; first, on the TYMNET side it shows the growth of it and really, the initial problems of it, which graphically shows it instead of saying it. And then the McDonnell Douglas part. Anyway, we can get into that when the time comes. Yost: Sounds good. My name is Jeffrey Yost, from the Charles Babbage Institute at the University of Minnesota, and I’m here today on April 4th, 2012, with Warren Prince of Tymshare and TYMNET. I’d like to begin just with some brief biographical stuff. Could you tell me where you were born, where you grew up? Prince: Born in Walnut Creek, California but grew up mostly in Arizona; Glendale, Arizona. And went through; started at the University of Arizona, and then joined the Army. -
