Abstract
Emulab's PlanetLab portal, hereafter known as the "portal,"
provides access to the large-scale, geographically
distributed resources of the PlanetLab testbed using the
integrated Emulab interface. The portal provides sophisticated
resource allocation, configuration, and management
services, while hiding from the user the underlying
low-level detail and complexity of distributed resource
provisioning and failure management. Moreover, it does
so while minimizing the impact on the underlying PlanetLab
system.
In the process of creating this portal and tracking PlanetLab's
evolving third-party service API, we identified
several key issues in the design of such platforms and the
management systems built on top of them. This paper
uses our portal as a basis for discussing these issues, and
presents the lessons we have learned during its design
and implementation.
