This document provides an overview of cloud computing. It begins by describing the disconnect between what businesses want from IT (e.g. fast experimentation) versus what IT wants (e.g. stability). Cloud computing is presented as filling this gap. The document defines cloud computing, discusses its characteristics such as pay-per-use and no long-term commitments. It also outlines the different types of cloud services (PaaS, IaaS, AaaS), common customers of cloud computing, and its advantages like economies of scale.
2. THE IT-BUSINESS DISCONNECT IS GROWING
Business wants IT wants
A place to Plenty of notice
experiment Predictability
Fast integration Stability
Looser IT Justification
restrictions
Responsiveness
Wham!
4. What Cloud Computing “IS NOT”?
It is not Network Computing
•Application and Data are not confined to
any specific Company’s Server
•No VPN Access
•Encompasses multiple companies, multiple
servers and multiple networks
It is not Traditional Outsourcing
•Not a contract to host data by 3rdparty
Hosting Business
•No subcontracting for computing services
for specific outside firm
5. DEFINITION: CLOUD COMPUTING
Cloud computing describes a new
supplement, consumption and delivery model
for IT services based on Internet, and it typically
involves the provision of dynamically scalable
and often virtualized resources as a service
over the Internet.

11. COMPONENTS TO CLOUD COMPUTING
Platform-As-A-Service (PaaS)
Delivers a computing platform and/or solution stack as a service
Facilitates deployment of applications without the cost and complexity of
buying and managing the underlying hardware and software layers
Infrastructure-As-A-Service (IaaS)
The delivery of computer IasS, typically platform virtualization
For example:
Virtual desktops
Grid computing
Applications-As-A-Service (AaaS) /Software-As-A-Service (SaaS)
Leverages the Cloud in software architecture
Eliminates the need to install and run the application on the customer's
own computer
Type:
Commercial
Government
12. CLOUD ADVANTAGES
Massive scale yields economies of scale.
Common infrastructure speeds innovation.
Dynamic, automated infrastructure easier
High utilization yields greater ROI.
Success drives IT investment.
IT is the business.
If your customers succeed, so do you.
