- 3. What is Cloud Computing? “Cloud computing is a style of computing where massively scalable IT-related capabilities are provided as a service across the Internet to multiple external customers” “Cloud computing: A pool of abstracted, highly scalable, and managed infrastructure capable of hosting end-customer applications and billed by consumption” “Cloud computing is Web-based processing, whereby shared resources, software, and information are provided to computers and other devices (such as smartphones) on demand over the Internet.”

- 7. Essential characteristics of Cloud Computing • On self demand servise • Ubiquitous n/w access • Resourse pooling • Rapid elasticity • Flexible using pay per use
- 8. Advantages of Cloud Computing • Lower Computing Cost • Improved Performance • Reduced Software Cost • Instant Software Updates • Unlimited Storage Capacity • Increased Data Reliability • Device Independence and the “always on!, anywhere and any place” • Free From Maintenance and the “no-need-to-know”
- 9. Cloud service models Software as a Service (SaaS) Def : SaaS is a software delivery methodology that provides licensed multi-tenant access to software and its functions remotely as a Web-based service. • Characteristics: • Scalable; Multi-tenant; Metadata driven configurability • Sometimes free; easy to use; good consumer adoption Examples :
- 10. • PaaS provides all of the facilities required to support the complete life cycle of building and delivering web applications and services entirely from the Internet. Platform as a Service (PaaS) • Highly scalable; multi-tier architecture; Multi tenant environments • Developers can upload a configured applications and it “runs” within the platform’s framework Examples :
- 11. • IaaS is the delivery of technology infrastructure as an on demand scalable service. Infrastructure as a Service (IaaS) • Offers full control of a company’s infrastructure; not confined to applications or restrictive instances • Sometimes comes with a price premium; can be complex to build, manage and maintain Examples :

Editor's Notes
- 1960 :- Supercomputers and Mainframe (massive computing was done through utility of supercomputers. The problem with this set-up arises from the cost needed to create a supercomputer or mainframe to the cost of maintaining it in optimal condition. As a result, leading to the idea of an “intergalactic computer network” by J.C.R. Licklider, who was responsible for enabling the development of ARPANET (Advanced Research Projects Agency Network) in 1969. His vision was for everyone on the globe to be interconnected and accessing programs and data at any site, from anywhere. Afterwards, John McCarthy who proposed the idea of computation being delivered as a public utility, similar to the service bureaus. 1990 :- The first milestones for cloud computing (The arrival of Salesforce.com, which pioneered the concept of delivering enterprise applications via a simple website. July 2002 :- Launch of Amazon web services (making information available through a web service focused as a retailer, provided a suite of cloud-based services including storage, computation and human intelligence. March 2006 and August 2006 :- S3 and EC2 (Elastic Compute Cloud) - infrastructure-as-a-service provider - making core computing infrastructure service (Cloud infrastructure) - pricing model ‘pay-per-use’ - shift of Amazon from being just a retailer to a strong player in the technology space - EC2 as a commercial web service that allows small companies and individuals to rent computers on which to run their own computer applications. April 2008 :- Launch of Google App Engine - first pure play technology company into the cloud computing market (browser-based enterprise applications) - a developer tool enables you to run your web applications on Google’s infrastructure. - Google App’s features - Dynamic web serving, persistent storage, automatic scaling and load balancing, Google API’s for authentication users and sending email November 2009 :- Launch of Windows Azure Beta belonged to Microsoft (the same concept as Google App) 2010 :- Concerns about the security of their corporate data in the cloud. Security, data privacy, network performance are likely to lead to a mix of cloud computing centers both within company firewall and outside of it. Learn how to secure, manage and monitor the growing range of external resources residing in the cloud including the improvement of faster processors and connections. **Amazon Launches EC2 Transaction Based Web Hosting Platform
