This document defines cloud computing and describes its key attributes and service delivery models. It explains that cloud computing resources are shared and accessed over the internet, users pay based on usage, and services can be provisioned on-demand at scale. The three main service delivery models are Infrastructure as a Service (IaaS), Platform as Service (PaaS), and Software as a Service (SaaS). IaaS allows users to deploy and run software on virtual machines and networks. PaaS enables custom app development using provider tools. SaaS offers applications running on the provider's infrastructure.

2. WHAT
IS
CLOUD ?
A Cloud is a
graphical
representation of
Network / Internet
It is in Computer terminology

3. Five Key Cloud Attributes:
1.Shared / pooled resources
2.Broad network access
3.On-demand self-service
4.Scalable and elastic
5.Metered by use

4.  Resources are drawn from a common pool
 Common resources build economies of scale
 Common infrastructure runs at high efficiency
Shared / Pooled Resources:

5. Broad Network Access:
 Open standards and APIs
 Almost always IP, HTTP, and REST
 Available from anywhere with an internet
connection

6. Metered by Use:
 Services are metered, like a utility
 Users pay only for services used
 Services can be cancelled at any time

7. CLOUD COMPUTING LIFESTYLE:

8. THREE SERVICE DELIVERY MODELS:
IaaS: Infrastructure as a Service
Consumer can provision computing resources within provider's
infrastructure upon which they can deploy and run arbitrary software,
including OS and applications.
PaaS: Platform as Service
Consumer can create custom applications using programming tools
supported by the provider and deploy them onto the provider's cloud
infrastructure
SaaS: Software as Service
Consumer uses provider’s applications running on provider's cloud
infrastructure
