| Abstract: | Utility or on-demand computing, a provisioning
model where a service provider makes computing infrastructure
available to customers as needed, is becoming increasingly
common in enterprise computing systems. Realizing this model
requires making dynamic, and sometimes risky, resource
provisioning and allocation decisions in an uncertain operating
environment to maximize revenue while reducing operating
cost. This paper develops an optimization framework wherein
the resource provisioning problem is posed as one of sequential
decision making under uncertainty and solved using a limited
lookahead control scheme. The proposed approach accounts for
the switching costs incurred during resource provisioning and
explicitly encodes risk in the optimization problem. Simulations
using workload traces from the Soccer World Cup 1998 web
site show that a computing system managed by our controller
generates up to 20% more revenue than a system without
dynamic control while incurring low control overhead. |
