Why It Is Hard to Build a Long-Running Service on PlanetLab
Justin Cappos and John Hartman, University of Arizona
Abstract
PlanetLab was conceived as both an experimental
testbed and a platform for long-running services. It has
been quite successful at the former, less so at the latter.
In this paper we examine why. The crux of the problem
is that there are few incentives for researchers to develop
long-running services. Research prototypes fulfill
publishing requirements, whereas long-running services
do not. Several groups have tried to deploy research
services, long-running services that are useful, but also
novel enough to be published. These services have been
generally unsuccessful. In this paper we discuss the difficulties in developing a research service, our experiences
in developing a research service called Stork, and
offer suggestions on how to increase the incentives for
researchers to develop research services.
