Title: Vatche Ishakian: Colocation as a Service: Strategic and Operational  
for Cloud Colocation (Practice Talk)
Title: Colocation as a Service: Strategic and Operational Services for  
Cloud Colocation
Speaker: Vatche Ishakian


By colocating with other tenants of an Infrastructure as a Service (IaaS)  
offering, IaaS users could reap significant cost savings by judiciously  
sharing their use of the fixed-size instances offered by IaaS providers.  
This paper presents the blueprints of a Colocation as a Service (CaaS)  
framework. CaaS strategic services identify coalitions of self-interested  
users that would benefit from colocation on
shared instances. CaaS operational services provide the information  
necessary for, and carry out the reconfigurations mandated by strategic  
services. CaaS could be incorporated into an IaaS offering by providers; it  
could be implemented as a value-added proposition by IaaS resellers; or it  
could be  directly leveraged in a peer-to-peer fashion by IaaS users. To  
establish the practicality of such offerings, this paper presents XCS -- a  
prototype implementation of CaaS on top of the Xen hypervisor. XCS makes  
specific choices with respect to the various elements of the CaaS  
framework: it implements strategic services based on a game-theoretic  
formulation of colocation; it features novel concurrent migration  
heuristics which are shown to be efficient; and it offers monitoring and   
accounting services at both the hypervisor and VM layers. Extensive  
experimental results obtained by running PlanetLab trace-driven workloads  
on the XCS prototype confirm the premise of CaaS -- by demonstrating the  
efficiency and scalability of XCS, and by quantifying the potential cost  
savings accrued through the use of XCS.
