In the near future, cloud providers will sell their users virtual machines
with CPU, memory, network, and storage resources whose prices constantly
change according to market-driven supply and demand conditions. Running
traditional operating systems in these virtual machines is a poor fit:
traditional operating systems are not aware of changing resource prices and
their sole aim is to maximize performance with no consideration for costs.
Consequently, they yield low profits. We present nom, a profit-maximizing
operating system designed for cloud computing platforms with dynamic
resource prices. Applications running on nom aim to maximize their profits
from their resources by optimizing for both performance and costs. The nom
kernel provides them with direct access to the underlying hardware and full
control over their private software stacks. Since nom applications know
there is no single ``best'' software stack, they adapt their stacks'
behavior on the fly according to the current price of available resources
and their private valuations of them. We show that in addition to achieving
up to 3.9x better throughput and up to 9.1x better latency, nom
applications yield up to 11.1x higher profits when compared with the same
applications running on Linux and OSv.
