  4. What is Cloud Computing? An emerging computing paradigm where data and services reside in massively scalable data centers and can be accessed from any connected devices over the internet. Businesses, from startups to enterprises Web 2.0-enabled PCs, TVs, etc. 4+ billion phones by 2010 [Source: Nokia] IBM Confidential Until Oct 8, 2007

  5. History In 1960 when John McCarthy opined that "computation may someday be organized as a public utility”. The term cloud had already come into commercial use in the early 1990s to refer to large ATM networks. In 1999, Salesforce.com was established by Marc Benioff, Parker Harris,and his fellows.They applied many technologies of consumer web sites like Google and Yahoo! to business applications. IBM extended these concepts in 2001 and in 2002 amazon.com played a key role in the development of cloud computing by modernizing their data centres.

  6. Cloud ComputingLayers • Infrastructure as a Service(IaaS) • Platform as a Service(PaaS) • Software as a Service(SaaS)

  7. Provisioning Interface Architecture Virtual Machines Provisioning Manager servers storage Monitoring Manager

  8. Cloud Computing Components • Cloud Application • Cloud Clients • Cloud Infrastructure • Cloud Platforms • Cloud Services • Cloud Storage

  9. Characterstics • COST • DEVICE AND LOCATION INDEPENDENCE • MULTI-TENANCY • RELIABILITY • SCALABILITY • SECURITY • SUSTANIBILITY IBM Confidential Until Oct 8, 2007

  10. Cloud ComputingServices • Search Engines • Webmail • Web Based Office Applications • Online Photo And Document Sharing

  11. Cloud ComputingServices • Large-scale web-based storage and computing power for building your own applications • Hosted Spam filtering

  12. Cloud Computing Providers • Amazon EC2 • Google Application Engine • Microsoft Azure • Salesforce.com

  13. Benefits • Ability to scale to meet changing user demands quickly, usually within minutes • Task oriented • Virtually no maintenance • Easy to develop your own web based applications that run in the cloud • Sharing of peak-load capacity among a large pool of users, improving overall utilization

  14. Benefits • Separation of application code from physical resources • Ability to use external assets to handle peak loads (not having to engineer for highest possible load levels) • Not having to purchase assets for one-time or infrequent intensive computing tasks

  15. Drawbacks • Canned solutions such may not be full featured, or too Task-oriented • Often limited or no technical support available • Often free services display ads • When there are technical issues you may lose access to your data or your application

  16. Drawbacks • No Control • Potential Regulatory Compliance issues • If the company hosting the application goes out of business you may lose access to your data or application permanently • You must have an Internet connection

  17. Why adopt cloud? • Access to computing power instantly • On demand allocation and deallocation of resources • More customers minimize capital expenditure. • Sharing of resources • Device and location independence
