What exactly is the Cloud ?
 The “Cloud” is a metaphor for the Internet
 On computer network diagrams the internet is
represented as a cloud
 National Institute of Standards & Technology (NIST)
and the Cloud Security Alliance defines Cloud
Computing as
 “a model for enabling convenient, on-demand
network access to a shared pool of configurable
computing resources (e.g., networks, servers, storage,
applications, services) that can be rapidly provisioned
and released with minimal management effort or service
provider interaction.”
