Exploiting Hardware Heterogeneity Within the Same Instance Type of Amazon EC2

Cloud computing providers might start with near homogeneous hardware environment. Over time, the homogeneous environment will most likely evolve into heterogeneous one because of possible upgrades and replacement of outdated hardware. In turn, the hardware heterogeneity will result into performance variation. In this paper, the authors look into the hardware heterogeneity and the corresponding performance variation within the same instance type of Amazon Elastic Compute Cloud (Amazon EC2). Standard large instance is selected as the example. They find out that there exist three different subtypes of hardware configuration in the standard large instance.
