3. Introduction

4. 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.”

29. Cloud implementation types

30. Cloud implementation types

31. Public Cloud • Owned and managed by service provider • Made available to the general public or a large industry group

32. Private Cloud • Operated solely for an organization • May be managed by the organization or a third party • Limits access to enterprise and partner network • Retains high degree of control, privacy and security

33. Community Cloud • shared infrastructure by several organizations which have shared concerns • May be managed by the organizations or a third party • Costs are spread over fewer users than a public cloud but more than a single tenant

34. Hybrid Cloud • Composition of two or more clouds (private, community, or public) bound together by standardized or proprietary technology that enables data and application portability

35. Conclusion

36. Conclusion Cloud Computing is the fastest growing part of network based computing . It Provides tremendous benefits to customers of all sizes: simple users, developers, enterprises and all types of organizations.
