Cloud-computing part 1

  1. 1. Cloud Computing isinternet based computing,where virtual shared serversprovide Software,infrastructure, platform,devices and other resources ona pay-as-you-use basis.“Why do it yourself if you canpay someone to do it for you?”Cloud Computing Session-1
  2. 2. A pool of highly scalable, abstracted infrastructure,capable of hosting end-customer applications, thatis billed by consumption.Cloud Computing Session-1

  6. 6. Cloud Computing Architecture Consists of:-1. Front End: It comprises client’s device and someapplication are needed for accessing cloud computingsystem.2. Back end: It refers to the cloud itself which mayencompass various computer machines, data storagesystems and servers.Cloud Computing Session-1

  8. 8.  Users select a task or service (either starting an application oropening a document). User’s request goes to the system management, which finds thecorrect resources and then calls the system’s appropriateprovisioning services. These services> Carve out the necessary resources in the cloud> Launch the appropriate web application> Opens the requested document. Web application is launched System’s monitoring functions track the usage of the cloud so thatresources are apportioned and attributed to the proper user(s). User is charged according to the amount of utilities and resourcesused.Cloud Computing Session-1
  9. 9. With cloud storage, data is storedon multiple third-party servers,rather than on the dedicatedservers.When storing data, the user sees avirtual server—that is, it appearsas if the data is stored in aparticular place with a specificname.In reality, the user’s data could bestored on any one or more of thecomputers used to create thecloud.Cloud Computing Session-1

  16. 16.  Cloud Computing enables a shift from the computer to theuser, from applications to tasks, and from isolated data todata that can be accessed from anywhere and shared withanyone. The user no longer needs to remember where the data is.All that matters is that the data is in the cloud, and thusimmediately available to that user.Cloud Computing Session-1
  17. 17. • There are many definitions of cloud services but, the NISTdefinition is the most widely accepted definition used today.• Whole system is administered via a central server that isalso used for monitoring client’s demand and trafficensuring smooth functioning of the system.Cloud Computing Session-1
