Erik Brynjolfsson:  Cloud Computing and Electricity: Beyond the Utility Model. Assessing the strengths, weaknesses, and general applicability of the computing-as-utility business model.

“Definitions for cloud computing vary. From a practitioner standpoint: “Cloud computing is on-demand access to virtualized IT resources that are housed outside of your own data center, shared by others, simple to use, paid for via subscription, and accessed over the Web.” From an academic perspective: “Cloud computing refers to both the applications delivered as services over the Internet and the hardware and systems software in the data centers that provide those services. … The data center hardware and software is what we will call a cloud. When a cloud is made available in a pays-as-you-go manner to the public, we call it a public cloud; the service being sold is utility computing.”

Technical weaknesses of the utility model
“Along with its strengths, however, the electric utility analogy [Both are what economists call general-purpose technologies. … General-purpose technologies, or GPTs, are best thought of not as discrete tools but as platforms on which many different tools, or applications, can be constructed.(citat fra Carr)/LH] also has three technical weaknesses and three business model weaknesses.”:

• The Pace of Innovation
• The Limits of Scale
• Latency: Distance is Not Dead.

Beyond Electricity: The Business Model of the Cloud
“Important as the technical differences are between electricity and cloud computing, the business model differences are even more profound.”:

• Complementarities and Co-invention
• Lock-in and Interoperability
• Security

Informationsteknologi: Gamle og nye metaforer

“I det følgende vil jeg gennemgå disse tre grundproblemer:

• Skal informationsteknologi iagttages som en maskine eller et medie?
• Skal information iagttages som susbstans eller forskel?
• Skal brugeren iagttages som informations-producent (redskabsmetaforen) eller som kommunikator (mediemetaforen)?”(p. 195 – 196)

“Normalt opfatter man informationsteknologi som et redskab der kan gøre hele verden tilgængelig for os, dvs. kan gøre forholdet mellem os selv og vores omverden transparent. //
Jeg vil imidlertid hævde at informationsteknologiens funktion er den modsatte: At informationsteknologi ikke er en kompleksitetsforøgende, men kompleksitetsreducerende teknologi, eller rettere: at informationsteknologi er spundet ind i det dilemma, vi stilles i når vi skal overleve i en kompleks verden: At vi skal forholde os til stadig større mængder information, dvs knytte an til og samtidig reducere kompleksiteten af en stadigt mere kompleks omverden.” (p. 196)
