More than bin packing: Dynamic resource allocation strategies in cloud data centers

作者：

Highlights：

• We compare VM allocation strategies for cloud environments experimentally.

• The experiments analyze a set of 44 combinations of placement and reallocation controllers.

• Periodic reallocation has substantial impact on the overall energy efficiency.

• The results also show that aggressive VM placement in combination with VM reallocation strategies achieve highest efficiency.
