3. What are Clouds? Clouds are “Virtual Clusters” Clouds support access of(lease of) computer instances Instances accept data and job descriptions (code) and return results that are data and status flags The datacenter with hardware and software is what we will call a Cloud.

5. What is Cloud Computing “A computing cloud is a set of network enable services providing scalable, QoS guaranteed, normally personalized, inexpensive computing infrastructures on demand, which could be accessed in a simple and pervasive way.”
