The Cloud
Why now?
security: already an issue (laptops, intranets, usb sticks)
shadow IT: legal compliance, integration, service budget
legal aspects: EU Data Protection Directive
loss of control/ownership/privacy
Richard Stallman: "It's worse than stupidity: it's a marketing hype campaign" (source Guardian)
lock-in: api-equivalents, data portability, cloud computing manifesto
English-centric
human costs: AWS Platinum Premium support: 15'000$/month
Cloud computing is Internet-based computing, where technological capabilities are maintained off premises and delivered on demand as a service via the internet, not unlike a public utility.
