1Paradigm shift ?If computers of the kind I have advocated become the computers of the future, then computing may someday be organized as a public utility just as the telephone system is a public utility... The computer utility could become the basis of a new and important industry.

John McCarthy, speaking at the MIT Centennial in 1961

John McCarthywas responsible for the coining of the term "Artificial Intelligence" in his 1955 proposal for the 1956Dartmouth Conferenceand is the inventor of theLispprogramming language.http://en.wikipedia.org/wiki/John_McCarthy_(computer_scientist) 2Utility ComputingUtility Computingis the packaging ofcomputing resources, such as computation, storage and services, as a metered service similar to a traditionalpublic utility(such aselectricity,water,natural gas, ortelephone network). http://en.wikipedia.org/wiki/Utility_computing

This model has the advantage of a low or no initial cost to acquire computer resources; instead,computational resourcesare essentially rented - turning what was previously a need to purchase products (hardware, software and network bandwidth) into a service.

3ServiceIs software a product or a service?So from the legal perspective software is really a product. I mean, a service. Sorry for this lapse.http://en.wikipedia.org/wiki/Service_(economics)http://se.ethz.ch/~meyer/publications/softdev/product-service.pdf

11Key Benefit of Cloud ComputingEconomic Element Pay-as-you-go Pay-as-you-grow Utility based payment Lower TCO

Architectural Element Simple, development Abstract environment Easy & Agile Development Device & Location Independent 24x7 Support(SLA) Secure Storage Management Highly Automated

Strategic Element Focus on your core business Reliability & Scalability Lower Capital ExpenditureGreater business flexibility:A cloud model gives you the ability to respond to business demands more effectively and helps ensure employees have on-demand access to critical business information, customers, partners, and each other, using nearly any device, from virtually anywhere. The result: They can give priority to the most critical business tasks first.Greater resource agility:The management burden of anticipating and building out excess capacity IT infrastructure decreases. The resultless management, maintenance, and deployment time, with the additional benefit of greater scalability to more easily handle peaks in demand.Managed costs:From a financial perspective, you can manage costs as a capital expense or an operational expense depending on what works best for your business.Smaller carbon footprint:At the same time, using off-premises IT infrastructure has the additional value of decreasing your environmental impact through a reduction in the physical resources required to run on-premises systems.Increased Mobility:Employees can access information from wherever they are, instead of having to remain at their desks.Reduced work load and maintenance:IT pros need not to worry anymore about hardware, and latest software upgrades.Safe and Secure network:Security could improve due to centralization of data, increased security-focused resources, etc.,Security is often as good as or better than under traditional systems, in part because providers are able to devote resources to solving security issues that many customers cannot afford. The complexity of security is greatly increased when data is distributed over a wider area and / or number of devices.

12Key Factor of Cloud ComputingCostScalabilityFlexibilityAvailabilityPortabilityCollaboration

http://www.b10wh.com/2009/02/the-size-of-the-company-does-not-reflect-on-utilization-of-cloud-computing/VSSecurityPrivacySLAReduce run time and response timeFor applications that use the cloud essentially for running batch jobs, cloudcomputing makes it straightforward to use 1000 servers to accomplish a task in1/1000 the time that a single server would require.

Minimize infrastructure riskIT organizations can use the cloud to reduce the risk inherent in purchasing physicalservers. Will a new application be successful? If so, how many servers are neededand can they be deployed as quickly as the workload increases? If not, will a largeinvestment in servers go to waste? If the applications success is short-lived, willthe IT organization invest in a large amount of infrastructure that is idle most of thetime?

14Category of Cloud ComputingPublic Cloud The public cloud is standardized cloud computing where all resources like applications and storage is made available to general public over the internet by services provider itself, which offers it free of cost or pay-per use basis.

Hybrid Cloud Hybrid cloud can be defined as use of both physical hardware and virtualized cloud server instance together to provide a single common service. Two separate clouds joined together or combination of virtualized cloud server instances used together with real physical hardware is also known as Combined cloud.

Private Cloud Private cloud provides hosted services to a limited number of people, may be within the cooperation, behind a firewall and it is also called internal cloud.

TimesMachineis a collection of full-page image scans of the newspaper from 18511922 (i.e., the public domain archives). Organized chronologically and navigated by a simple calendar interface, TimesMachine provides a unique way to traverse the historical archives of The New York Times. Topics ranging from the Civil War to the sinking of the Titanic to the first cross-country auto race to womens fashions in the 20s are just a few electronic flips away. And of course, theres the advertisements.

This all adds up to terabytes of data, in a less-than-web-friendly format. Soreusing the EC2/S3/Hadoop method I discussed back in November, I got to work writing a few lines of code. UsingAmazon Web Services,Hadoopand our own code, we ingested 405,000 very large TIFF images, 3.3 million articles in SGML and 405,000 xml files mapping articles to rectangular regions in the TIFFs. This data was converted to a more web-friendly 810,000 PNG images (thumbnails and full images) and 405,000 JavaScript files all of it ready to be assembled into a TimesMachine. By leveraging the power of AWS and Hadoop, we were able to utilize hundreds of machines concurrently and process all the data in less than 36 hours.
