Scalable Services For Digital Preservation Ross King

The document discusses the Planets Interoperability Framework, which defines a service-oriented architecture for digital preservation. It implements common services like authentication and authorization. It also provides a workflow enactment service and engine. The framework allows jobs to be submitted to grid/cloud resources for improved scalability. Experimental results show that performance scales with the number of nodes, though open issues around security, reliability and standardization remain. Map-reduce is proposed as a model for migrating large digital objects across multiple nodes in a distributed manner.
