Compute cloud has increasingly become the platform for a large amount of computation and storage tasks that used to be hosted on the Internet or in clusters. Modern compute clouds are based on the virtualization technology and allow applications to share the underlying computing resources (such as CPU, memory and networking bandwidth) by running in isolated virtual machines (VM). A key factor for the economic success of a compute cloud is capacity planning, which refers to the procedure of allocating resources commensurate with VM workload demands and application performance requirement. In this talk, I will introduce several new capacity planning techniques. These include: (1) a technique to leverage the power of workload multiplexing by provisioning multiple VMs as a whole; (2) a network bandwidth-oriented VM placement technique to save network bandwidth usage; (3) a practical method to combine network oriented VM placement with traditional CPU (or memory) oriented placement algorithms.
