Title:

Application Informed Tuning of Virtualized Environments

 

Abstract:

Virtualization is currently being used in cloud computing environments and

traditional IT environments to improve the flexibility and manageability of

the computing infrastructure, to enable the sharing of computing resources,

and to achieve economies of scale. 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.
