Abstract

Memory deduplication allows cloud infrastructure
providers to increase the profit of memory resources by
taking advantage of the redundant nature of virtual machines footprint. Although it is an important feature to manage the memory resources of a cloud system efficiently, unfortunately, it enables different types of side-channel attacks which, in practice, means disabling memory deduplication. In this paper, we present Slicedup, a tenant-aware memory deduplication mechanism that prevents side-channel attacks. Our proposal enables cloud providers to get the deduplication saving benefits while preventing side-channel attacks among tenants. Since Slicedup is a design-solution, it can be implemented in any
operating system, regardless of its version, architecture or any other system dependence. Finally, we show how Slicedup prevents side-channel attacks while providing similar memory savings when the number of tenants per physical host is low.
