Large public cloud infrastructure can utilize
power which is generated by a multiplicity of power plants. The cost of
electricity will vary among the power plants and each will emit different
amounts of carbon for a given amount of energy generated. This infrastructure
services traffic that can come from anywhere on the planet. It is desirable,
for latency purposes, to route the traffic to the data centre that is closest
in terms of geographical distance, costs the least to power and emits the
smallest amount of carbon for a given request. It is not always possible to
achieve all of these goals so we model both the networking and computational
components of the infrastructure as a graph and propose the Stratus system
which utilizes Voronoi partitions to determine which data centre requests
should be routed to based on the relative priorities of the cloud operator.
