Cloud Computing Diffusion of Innovations Diane Burling
Why Cloud Computing • Proper and affordable • Accessibility
Need • Sold on demand, typically by the minute or the hour; • Elastic -- a user can have as much or as little of a service as they want at any given time; and the service is fully managed by the provider (the consumer needs nothing but a personal computer and Internet access)
Research • Dates back to 1960, computer scientist John Mccarthy • 2.Internet hosting services expand on what is already in place- provide hosting services: • Infrastructure-as-a-Service (IaaS) • Platform-as-a-Service (PaaS) • Software-as-a-Service (SaaS). • Sold on demand, elastic, no managing required by user
Development • Privacy Issues • Compliance • Legal • Open source/standards • Security • Availability/performance • Sustainability • Clients
Commercialization • Public cloud • Community cloud • Hybrid cloud • Private cloud • Billed as a utility
