The advantages and disadvantages of Cloud Computing



2. Cloud Computing The practice of using anetwork of remoteservers hosted on theinternet to store,manage and processdata, rather than alocal server or apersonal computer. 3. Cloud ComputerHow Cloud Computing Work? 4. Cloud Computing You have to purchase software or softwarelicenses to give employees the tools theyrequire. Whenever you have a new hire, you have tobuy more software or make sure yourcurrent software license allows anotheruser. 5. Cloud Computing That applicationwould allow workersto log into a Web-basedservice whichhosts all the programsthe user would needfor his or her job. 6. Cloud Computing The only thing the user's computer needs tobe able to run is the cloud computingsystem's interface software, which can beas simple as a Web browser, and the cloud'snetwork takes care of the rest. 7. Cloud Computing You have an e-mail account with a Web-based e-mailservice like Hotmail, Yahoo! Mail or Gmail,. Instead of running an e-mail program on yourcomputer, you log in to a Web e-mail accountremotely. The software and storage for your account doesn'texist on your computer -- it's on the service'scomputer cloud. 8. Cloud ComputingCloud Computing Architecture 9. Cloud Computing The front end is the side the computer user, or client, sees. Includes the client's computer (or computer network) andthe application required to access the cloud computingsystem. Not all cloud computing systems have the same userinterface. Other systems have unique applications that providenetwork access to clients. 10. Cloud Computing The back end is the "cloud" section of the system. There are the various computers, servers and data storagesystems that create the "cloud" of computing services. Each application will have its own dedicated server andCentral server administer. 11. Cloud ComputingThe six (6) reasons you would rely onanother computer system to runprograms and store data? 12. Cloud Computing1. Brings hardware cost down. (No need for a faster computer or memory.2. Corporations and Companies dont have to buy a set of software or licensefor every employee. Instead paid a metered fee.3. Clients can access their application and data from anywhere at anytime;and data would not be confined to hard drives or corporate networks.4. Servers and digital storage device take up space. Cloud computing givecorporation and companies the option of storing data on some one elseshardware removing the need for physical space on the front end.5. Corporation and Companies might save money on IT support. Streamlinedhardware would, in theory, have fewer problems than a networkof heterogeneous (different) machines and operating systems.6. If the cloud computing system's back end is a grid computing system, thenthe client could take advantage of the entire network's processing power. 13. Cloud ComputingWhile the benefits of cloudcomputing seem convincing, thereany potential problems? 14. Cloud Computing The idea of handing over important datato another company worries somepeople. Corporate executives might hesitate totake advantage of a cloud computingsystem because they can't keep theircompany's information under lock andkey. If a client can log in from any locationto access data and applications, it'spossible the client's privacy could becompromised. Cloud computing companies will needto find ways to protect client privacy. 15. Cloud Computing The counterargument to thisposition is that the companiesoffering cloud computingservices live and die by theirreputations. It benefits these companies tohave reliable security measuresin place. Also it's in their interest toemploy the most advancedtechniques to protect theirclients' data. 16. Cloud Computing Does the user or company subscribing to the cloudcomputing service own the data? Does the cloud computing system, which provides theactual storage space, own it? Is it possible for a cloud computing company to deny aclient access to that client's data? 17. Cloud ComputingHow will cloud computing affectother industries? 18. Cloud Computing If companies switch to using streamlined computersystems, they'll have fewer IT needs. Some industry experts believe that the need for IT jobswill migrate to the back end of the cloud computingsystem. An autonomic computing system is self-managing, whichmeans the system monitors itself and takes measures toprevent or repair problems. This auto computing system is mostly theoretical. But, ifautonomic computing becomes a reality, it could eliminatethe need for many IT maintenance jobs. 19. Cloud Computing ConclusionModern technology is both a blessing and a curse. While mobile devices andweb services can deliver quick access to information and even quickerconnection to other people, there is a downside: the loss of control over data.To regain confidence in the privacy and security of personal data, newtechnology applications need to manage sensitive data rigorously and provideusers with strong controls over its ownership , distribution and properties.ByLB
