EaaS: Image and Object Archive — Requirements, Implementation and Example Use-Cases
With our distributed architecture and an efficient network transport protocol, we are able to provide Emulation as a Service quite efficiently while at the same time allowing owners of digital objects to remain in complete control over their intellectual property. Using copy-on-write technology it is possible to create a multitude of different configurations and flavors of the same system with only minimal storage requirements. Derivatives and their respective "parent" system can be handled completely independent from each other and withdrawing access permissions for a parent will automatically invalidate all existing derivatives. This allows for a very efficient and flexible handling of curation processes that involve the installation of (licensed) software, personal information and user customizations.
