“The interesting thing about cloud computing is that we’ve redefined cloud computing to include everything that we already do…. I don’t understand what we would do differently in the light of cloud computing other than change the wording of some of our ads.”

``A Cloud is a type of parallel and distributed system consisting of a collection of inter-connected and virtualized computers that are dynamically provisioned and presented as one or more unified computing resource(s) based on service-level agreements established through negotiation between the service provider and consumers”

Cloud Computing
Cloud computing is a model for enabling convenient, ondemand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This cloud model promotes availability and is composed of five essential characteristics, three service models, and four deployment models
Cloud Computing
Let’s assume that you have a requirement to operate 100 servers over the course of three years. One option is to lease them at $0.40 per instance-hour, which would cost approximately 100 servers * $0.40 instance-hour * 3 years *
8,760 hours/year = $1,051,200.
Another option is to buy them. Let’s assume the cost to buy each server is
$1,500, that you need two staff members at $100,000 per year to administer the servers, and
