  • 1. CLOUDCOMPUTING
  • 2. CONC EPT
  • 3. Cloud computing is a technology that usesthe internet and central remote servers tomaintain data and applications.
  • 4. Cloud computing allows consumers andbusinesses to use applications withoutinstallation and access their personal files atany computer with internet access.
  • 5. This technology allows for much moreefficient computing by centralizing storage,memory, processing and bandwidth.
  • 6. A simple example of cloud computing is Yahooemail, Gmail, or Hotmail etc. You dont need asoftware or a server to use them. All a consumerwould need is just an internet connection and youcan start sending emails. The server and emailmanagement software is all on the cloud (internet) and is totally managed by the cloudservice provider Yahoo , Google etc. Theconsumer gets to use the software alone andenjoy the benefits.
  • 7. SOFTWARE, DATABASE
  • 8. BENEFI TS
  • 9. Cost is claimed to be reduced and in apublic cloud delivery model capitalexpenditure is converted to operationalexpenditure, as infrastructure is typicallyprovided by a third-party and does not needto be purchased for one-time or infrequentintensive computing tasks.
  • 10. Device and location independence enableusers to access systems using a webbrowser regardless of their location or whatdevice they are using (e.g., PC, mobilephone).
  • 11. Virtualization technology allows serversand storage devices to be shared andutilization be increased. Applications can beeasily migrated from one physical server toanother.
  • 12. Reliability is improved if multipleredundant sites are used, which makeswell-designed cloud computing suitable forbusiness continuity and disaster recovery.
  • 13. Maintenance of cloud computingapplications is easier, because they do notneed to be installed on each userscomputer and can be accessed fromdifferent places.
  • 14. SECURI TY
  • 15. Security could improve due tocentralization of data, increased security-focused resources, etc., but concerns canpersist about loss of control over certainsensitive data, and the lack of security forstored kernels.•KERNEL IS THE CENTRAL PART OF THE SYSTEM
  • 16. Security is often as good as or better thanother traditional systems, in part becauseproviders are able to devote resources tosolving security issues that many customerscannot afford.
  • 17. However, the complexity of security isgreatly increased when data is distributedover a wider area or greater number ofdevices and in multi-tenant systems that arebeing shared by unrelated users.
  • 18. In addition, user access to security auditlogs may be difficult or impossible.
