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!

3. WHO’S FILLING THE GAP?
Cloud computing

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.
What’s new?

7. CLOUD COMPUTING:
THE LATEST EVOLUTION OF HOSTING

8. CLOUD COMPUTING:CHARACTERITICS
 Massive, abstracted infrastructure
 Components decided for you
 Dynamic allocation, scaling, movement of
applications
 Pay per use
 No long-term commitments
 OS, application architecture independent
 No hardware or software to install

9. CLOUD’S CUSTOMERS
 Startups
 Web-based business, SaaS, collaboration services, widget
providers, mobile services, social networking
 Small businesses
 Online businesses, online presence, collaboration, enterprise
integration
 Enterprises
 R&D projects, quick promotions, widgets, online
collaboration, partner integration, social networking, new business
ventures

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.
