This paper argues for exertion-based metrics, such as disk time, for the access cost component of cloud storage billing. It also discusses challenges in supporting fair and predictable exertion accounting, such as significant inter-workload interference effects for storage access, and a performance insulation approach to addressing them.
In this paper, we shed light on some core challenges in building a cloud-scale resource management system based on our last five years of research and shipping cluster resource management products.
Elasticity should be treated as a first class system parameter. Particularly in large cloud environments, elastic applications would benefit if the underlying infrastructure provided primitives for elasticity and were themselves elastic. If you want to provide an elastic service and the cloud does not provide good primitives for…
In this paper, we examine data from real-world virtualized deployments to characterize common management workflows and assess their impact on resource usage in the datacenter. We show that while many end-user applications are fairly light on I/O requirements, the management workload has considerable network and disk I/O requirements.…
Virtualization is an important enabling technology for many large private datacenters and cloud computing environments. Virtual machines often have complex expectations of their runtime environment such as access to a particular network segment or storage system. Similarly, the runtime environment may have complex expectations of a virtual machine’s…
