What is a Cloud service?
◦ Self-service: If you can'tgo to a Web site, set up your account(s), and start provisioning over the Web yourself, then it's not a cloud service. ◦ Commodity pricing: Self-service enables cloud service providers to keep costs down. You have an array of pay-per-use (or subscription) options, and if you don't like them, you go somewhere else. ◦ Transparent scalability: If you want more of a service, you go to your serviceprovider's Web site and specify more. Your bill goes up accordingly, but otherwise, you don't have to think about it. ◦ Shared infrastructure: Cloud services have a one-to-many relationship with their customers. Infrastructure-as-a-service providers move around customer VMs as needed, so that VMs from multiple customers often run on the same server. ◦ Machine Addressability: None unless we are talkingabout Infrastructure as a Service
Is there such a thing as a private cloud?: No, that is server virtualization. However IBM set up a cloud appliance that is a turnkey system that meets most of the criteria of a public cloud service and set it up in-house. (CloudBurst) Will cloud services replace the Microsoft desktop?: I don’t see that happening in the near future, ratherwe will have a mix of Office apps and cloud data storage like DropBox. Do cloud services mean the end of IT as we know it?: Definitely many jobs will be loss because of the automated administration nature of the cloud. Even the development skills are going to be modified. Does the cloud really enable anything new?: it enables something completely new: data analysis on a monster scale withcommodity hardware. But the most exciting potential of the cloud is as a platform for Internet-based services that deliver entirely new capabilities fast without the upfront costs
