PDS: a virtual execution environment for software deployment
The Progressive Deployment System (PDS) is a virtual execution environment and infrastructure designed specifically for deploying software, or “assets”, on demand while enabling management from a central location. PDS intercepts a select subset of system calls on the target machine to provide a partial virtualization at the operating system level. This enables an asset’s install-time environment to be reproduced virtually while otherwise not isolating the asset from peer applications on the target machine. Asset components, or “shards”, are fetched as they are needed (or they may be pre-fetched), enabling the asset to be progressively deployed by overlapping deployment with execution. Cryptographic digests are used to eliminate redundant shards within and among assets, which enables more efficient deployment. A framework is provided for intercepting interfaces above the operating system (e.g., Java class loading), enabling optimizations requiring semantic awareness not prese...
