SUMMARY:Towards Predictable Data Centers- Why Johnny can't use the cloud a

DESCRIPTION:The shared nature of the network in today’s multi-tenant dat
 a centers implies that network performance for tenants can vary significan
 tly. This makes application performance and tenant costs unpredictable\, b
 oth key concerns in data centers. Motivated by these factors\, the Predict
 able Data Center project aims to address such performance unpredictability
  by extending the tenant-provider interface to explicitly account for the 
 network. To this end\, we provide tenants with a virtual network that guar
 antees their network bandwidth. This talk will provide a project overview 
 with a focus on two key questions\; what motivated our virtual network des
 igns and how can they be enforced. We argue that our virtual networks ensu
 re a good trade-off between tenant guarantees and tenant costs by guarante
 eing their "aggregate" network bandwidth.
