  1. 1. ISM – SML 713 How Cloud Computing has Transformed Information Management? By : Pawandeep Singh Maniktala 2012SMN6706 Bhushan Kumar 2012SMN6788 Himanshu Singhal 2012SMN
  2. 2. What is Information Systems Management (ISM)? • The ISM program combines the fundamental intellectual content of both Computer Science and Business Management Economics. • An increasingly larger number of companies and institutions have concluded that their daily operations have an indispensable reliance on computer-based systems.
  3. 3. Common Information Management issues • Large number of disparate systems • Little integration or coordination between information systems • No clear strategic direction for the overall technology environment. • Range of legacy systems requiring upgrading or replacement • Limited and patchy adoption of existing information systems by staff. • Poor quality of information, including lack of consistency, duplication, and out-of-date information.
  4. 4. Potential Solution : Cloud Computing !
  5. 5. Market for Cloud Computing:
  6. 6. Potential Solution : Cloud Computing
  7. 7. Cloud Services
  8. 8. What is Cloud Computing ? • a new delivery model for IT services based on the Internet, • it involves over-the-Internet provision of dynamically scalable & virtualized resources • CC frequently takes the form of web-based tools or applications that users can access and use through a web browser as if it were a program installed locally on their own computer. • Cloud Computing is the fifth generation of computing (after Mainframe, Personal Computer, Client-Server Computing, and the web).
  9. 9. What is Cloud Computing ? 1. CC providers deliver common business applications online that are accessed from another Web service or software like a Web browser , while the software and data are stored on servers. 2. The major cloud service providers include Sales force, Amazon and Google.
  10. 10. Architecture of Cloud Computing 1. The systems architecture of the software systems involved in the delivery of cloud computing, typically involves multiple cloud components communicating with each other over application programming interface, usually web services. 2. The two most significant components of cloud computing architecture are known as the front end and the back end. The front end is the part seen by the client, i.e. the computer user. This includes the client’s network (or computer) and the applications used to access the cloud via a user interface such as a web browser. The back end of the cloud computing architecture is the ‘cloud’ itself, comprising various computers, servers and data storage devices.
  11. 11. Benefits of Cloud Computing ? • Provides access to the latest software versions • Can be accessed from anywhere • Resiliency and Redundancy • Improved services • Environmentally friendly • Sharing info is not restricted to size • Innovation & Competitiveness
  12. 12. Why Cloud Computing ? • Customer Perspective      In one word: economics, minimum TCO(Total Cost of Ownership) Faster, simpler, cheaper to use cloud applications No additional capital required for servers and storage No ongoing operational expenses for running datacenter Applications can be accessed from anywhere, anytime • Vendor Perspective      Easier for application vendors to reach new customers Lowest cost way of delivering and supporting applications Ability to use commodity server and storage hardware Ability to drive down data center operational cots In one word: economics
  13. 13. Downsides Cloud Computing ? • Immature technologies • Connection • Migrations and customisations • Expectations • Data Sovereignty
  14. 14. Industry Examples: Google Docs ENTERPRISE MARKET MID-MARKET SMALL BUSINESS
  15. 15. Industry Examples: Salesforce CRM ENTERPRISE MARKET Enterprise Std Enterprise Std ~65,000 ~65,000 ~30,000 ~30,000 ~30,000 ~30,000 ~6,300 ~6,300 ~5,800 ~5,800 ~5,500 ~5,500 MID-MARKET ~9,000 ~9,000 SMALL BUSINESS ~4,000 ~4,000 ~~3,500 3,500 ~3,200 ~3,200 Number of Subscribers ~3,000 ~3,000
  16. 16. Conclusions        Cloud Computing is the fastest growing part of IT Tremendous benefits to customers of all sizes Cloud services are simpler to acquire and scale up or down Key opportunity for application and infrastructure vendors Public clouds work great for some but not all applications Private clouds offer many benefits for internal applications Public and private clouds can be used in combination
