Metrics and techniques for quantifying performance isolation in cloud environments

Quantifying the Isolation Characteristics in Container Environments

In recent years, container technologies have attracted intensive attention due to the features of light-weight and easy-portability. The performance isolation between containers is becoming a significant challenge, especially in terms of network throughput and disk I/O. In traditional VM environments, the performance isolation is often calculated based on performance loss ratio. In container en...

Seawall: Performance Isolation for Cloud Datacenter Networks

While today’s virtual datacenters have hypervisor based mechanisms to partition compute resources between the tenants co-located on an end host, they provide little control over how tenants share the network. ˆis opens cloud applications to interference from other tenants, resulting in unpredictable performance and exposure to denial of service attacks. ˆis paper explores the design space for a...
