This document provides an introduction to cloud computing and infrastructure as a service (IaaS). It defines cloud computing and IaaS, discusses the benefits of cloud computing like elasticity and pay per use. It also covers the components of IaaS including storage, servers, and networking. Examples of IaaS providers like Amazon Web Services, Google Compute Engine, and IBM Smart Cloud Enterprise are provided. The conclusion reiterates that IaaS allows users to rent virtual infrastructure resources and maintains security is important.

2.  INTRODUCTION
 BASICS CONCEPT OF CLOUD COMPUTING
 INFRASTRUCTURE AS A SERVICE
 COMPONENT OF IAAS
 SERVICE MODELS OF IAAS
 CONCLUSION

3.  Cloud
 large pool.
 easily usable and accessible virtualized resources.
 pay-per-use model.
 Cloud Computing
 Use to access the application over Internet.
 Manipulation, Configuring and Accessing.

4.  Benefits of Cloud Computing.
 Self-service provisioning
 Elasticity
 Pay per use
 Security & Privacy.
 Biggest issues.
 Provided by third-party.
 Risk of Sensitive information.
 Types of Cloud Computing Models.
 Deployment Model.
 Service Model.

7.  Provide Storage, Server, Networking Component.
 Flexible, Efficient of Computer Hardware and
Portability.
 Standardized Virtual Provider.
 Also called as Hardware as a Service(HaaS).

10.  Business application.
 Technical site
 Amazon Web Server(AWS).
 Google Compute Engine.
 IBM Smart Cloud Enterprise etc…
 AWS
 Collection of remote computing and Called as Web Service.
 Amazon.com have cloud computing platform.
 Amazon Elastic Compute cloud.
 Central part of Amazon.com.
 Allow user to rent virtual computer on that run their own
Application.

11.  More complex for maintaining the Security.
 About overview of cloud computing.
 Small discussion about IaaS.
