Are Your Papers in Order? Developing and Enforcing Multi-tenancy and Migration Policies in the Cloud

As cloud usage continues to increase, new issues with respect to managing and securing resources in the cloud are becoming more apparent. While some people may believe that security and privacy in the cloud can be addressed without the consumer considering the physical location and internal structure of the cloud, we show that this is clearly not the case. Furthermore, we describe a mechanism by which cloud consumers can inform cloud providers of their requirements in a manner that still allows the cloud to remain dynamic and flexible. Specifically, this paper explores the analogy between human migration in the real world and virtual machine migration in an IaaS cloud environment. It addresses issues such as jurisdictional control, zone evolution, migration, and instantiation based on an examination of these analogous real-world scenarios and their applicability to the cloud.
