De…nition of the Cloud
What is Cloud Computing?
“Cloud computing is a model for enabling convenient, on-demand
network access to a shared pool of con…gurable computing
resources (e.g., networks, servers, Storage, applications, and
services) that can be rapidly provisioned and released with minimal
management e¤ort or service provider interaction” - (NIST, USA)

PaaS
Cloud providers deliver a computing Platform that enables
application developers to develop, run and host their solutions
The underlying platform that includes network, servers,
operating systems, software for application development, etc
is managed by the Cloud provider
Pay-as-you-go model
Examples include: Google AppsEngine, Windows Azure
compute, Force.com and SalesForce, VMware.
