Application Informed Tuning of Virtualized Environments

Google Tech Talk April 16, 2009 ABSTRACT Speaker: Ashraf Aboulnaga, David R. Cheriton School of Computer Science, University of Waterloo Virtualization is currently being used in cloud computing environments and traditional IT environments to improve the flexibility and manageability of the computing infrastructure, and to enable the sharing of computing resources. This means that applications (such as database systems) are increasingly being run on virtual machines and using virtualized storage. The performance of an application in this environment is affected by the configuration and tuning decisions made at the virtual machine/storage level. In this talk, I will demonstrate that coordinating between the application and the virtualization environment when making these tuning decisions can result in significant performance gains. I will present three examples of such application informed tuning: (1) configuring multiple virtual machines running database workloads on the same physical server, (2) improving the caching decisions of a storage server running a database workload, and (3) scheduling a batch of Map-Reduce jobs running on a cluster of virtual machines. Speaker Info: Ashraf Aboulnaga is an Assistant Professor in the David R. Cheriton School of Computer Science at the University of Waterloo. His research interests are in the area of database management, with a current focus on database issues in virtualized and cloud computing environments, self-managing database <b>…</b>
