Cloud computing is a releasing individual and institutions from the traditional cvcle of buying-using-maintaining-upgrading IT resourcs - both hardware and software. Instead it is making IT resource accessible from anywhere and at proportions as required by the end user. Here is a brief introduction to this new transformation

Cloud Computing - An Introduction
- 1. Cloud Computing: A General Introduction Ravindra Dastikop [email protected] Cloud Complete
- 3. Cloud Computing: Simplified Cloud computing is a model of delivering computing resources from the Internet to the user. Computing resources: Software- Applications, OS, service Hardware ( processors, servers, memory, cards) information - encyclopedia, search engine User computer connected to the net mobile user Connected TV
- 4. Cloud service - An example when you get connected to service like Gmail, Hotmail etc - you are really connecting to a massive pools of servers somewhere out there on the internet Source: http://howtogeek.com
- 5. Why is it called Cloud Computing ? Because in network diagrams, the Internet is depicted as a cloud Source: http://howtogeek.com
- 6. Why is it called cloud ?
- 8. Technical Definition Cloud computing is a model for enabling convenient, ● on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) ●that can be rapidly provisioned and released with minimal management effort or service provider interaction.

- 36. Concept of cloud computing ●A concept is an instrument and a history, that is a bundle of possibilities and obstacles involved in the world as experienced – quote G S Granger ●Instrument - Using net as the source of computing resources and delivering them directly to the user ●Bundle of possibilities ○SAAS, IAAS ●History – Grid Computing, Distributed computing ●Obstacles - security, connectivity
- 37. Idea of Utility water, electricity , petrol ...
- 38. Conceptual Foundations ●Cloud computing concept has been derived from the Utility computing model. ○The Best example Utility computing ( Packaged, metered) model would be the electricity supply system and another concept which it depends on is the Grid computing model. ○Cloud computing has been mainly derived from the Mainframes concept. ○The main feature of cloud computing is the scalability and how it incorporates a part of virtualization.
- 39. Concept- Business ●Utility Computing- packaged, metered ●Produce in large supply in retail ○ Water ○ Electricity ●Whole buy- retail sale ●Build large and massive capacity and service is in and through individual units/users ○per MB
- 40. Paradigm ●Direct to U From the “ net” as against “on premise” ( DTH) ●Direct to user – TV channel subscription ●Use without owning- Ramco OnDemand Cloud ●Rental basis- Google for Enterprises ●Procure as u grow (Gmail start with 7GB and ask for more ) ●From NIL to FULL
- 41. Why cloud Computing is a compelling paradigm
- 43. Scalable Architecture ●Scales up to meet Business Goals ●Grids to handle fail-over, backup, disaster recovery & scalability ○Computing grid: for serving user requests ○Storage grid : File grid, Database grid ○Messaging grid: for real-time updates and chats
- 44. Superior Integration ●Integration across SaaS applications is far easy ○CRM integrating spreadsheet and email ●Small web services & aggregation (SOA) ○Evolve each service independently and rapidly ●Contextual integration- application + user's data and context
- 45. Performance Cloud gives better performance ●Caching ○HTML Page caching ○distributed server side object caching ○convert dynamic data into pre-computed static content ● For example ○Zoho Sheet ( online spread sheets) can be faster than loading complex Excel documents
- 46. Conclusion ●Cloud represents a new found land- migrate as early as possible ●Cloud computing represents a new Trend- embrace it ○It better to go with trend than to fight it ○More people learn on web

The resulting systems are called Information systems(IS). ● Enterprise Computing started with the advent of mainframe computers in the 60's. Over the years with the introduction of new computing devices, enterprise computing paradigm have transformed into new models- changing in scale and ubiquity. ○ mainframe ○ PCs, client-server models ○ Internet - web-based enterprise computing and customer-facing e-commerce models Cloud Computing has new potential for revolutionizing enterprise computing once again.
