CloudSight: A tenant-oriented transparency framework for cross-layer cloud troubleshooting.

Troubleshooting in an infrastructure-as-a-Service (IaaS) cloud platform is an inherently difficult task because it is a multi-player as well as multi-layer environment where tenant and provider effectively share administrative duties. To address these concerns, we present our work on CloudSight in which cloud providers allow tenants greater system-wide visibility through a transparency-as-a-service abstraction. We present the design, implementation, and evaluation of CloudSight in the OpenStack cloud platform. We also develop two example applications that make use of the CloudSight abstraction and use the applications to explore real cloud problems.
