Protection mechanisms for application service hosting platforms

The Application Service Hosting Platform (ASHP) has recently received tremendous attention from both industry and academia. An ASHP provides a shared highperformance infrastructure to host different Application Services (AS), outsourced by Application Service Providers (ASP). In this paper, we focus on the protection of ASHP, which has inherent requirement of sharing, openness, and mutual isolation. Different from a dedicated server platform, which is analogous with a private house, an ASHP is like an apartment building, involving the `host' - the ASHP infrastructure and the `tenants' - the AS. Strong protection and isolation must be provided between the host and the tenants, as well as between different tenants. Unfortunately, traditional OS architecture and mechanisms are not adequate to provide strong ASHP protection. In this paper, we first make the case for a new OS architecture based on the virtual OS technology. We then present three protection mechanisms we have deve...
