Gatekeeper: Supporting Bandwidth Guarantees for Multi-tenant Datacenter Networks

Cloud environments should provide network performance isolation for co-located untrusted tenants in a virtualized datacenter. We present key properties that a performance isolation solution should satisfy, and present our progress on Gatekeeper, a system designed to meet these requirements. Experiments on our Xen-based implementation of Gatekeeper in a datacenter cluster demonstrate effective a...

Cicada: Predictive Guarantees for Cloud Network Bandwidth

In cloud-computing systems, network-bandwidth guarantees have been shown to improve predictability of application performance and cost [1, 30]. Most previous work on cloudbandwidth guarantees has assumed that cloud tenants know what bandwidth guarantees they want. However, application bandwidth demands can be complex and time-varying, and many tenants might lack sufficient information to reques...

Enforcing Fairness in a Live-Streaming System

We describe a practical auditing approach designed to encourage fairness in peer-to-peer streaming. Auditing is employed to ensure that correct nodes are able to receive streams even in the presence of nodes that do not upload enough data (opportunistic nodes), and scales well when compared to previous solutions that rely on tit-for-tat style of data exchange. Auditing involves two roles: local...

Enforcing Fairness in Asynchronous Collaborative Environments

Many large-scale distributed applications rely on collaboration, where unrelated users or organizations share their resources for everyone's benefit. However, in such environments any node may attempt to maximize its own benefit by exploiting other's resources without contributing back. Collaborative systems must therefore deploy strategies to fight free-riders, and enforce collaborative behavi...

Enforcing Privacy in Cloud Databases

Outsourcing databases, i.e., resorting to Database-as-a-Service (DBaaS), is nowadays a popular choice due to the elasticity, availability, scalability and pay-as-you-go features of cloud computing. However, most data are sensitive to some extent, and data privacy remains one of the top concerns to DBaaS users, for obvious legal and competitive reasons. In this paper, we survey the mechanisms th...
