Managing large computing infrastructures in a reliable and efficient way requires system configuration tools which accept higher-level specifications. This paper describes an interface between the established configuration tool LCFG, and the experimental configuration tool PoDIM. The combined system is used to generate explicit real-world configurations from high-level, constraint-based specifications. The concept is validated using live data from a large production installation. This demonstrates that a looselycoupled, multi-layer approach can be used to construct configuration tools which translate high-level requirements into deployable production configurations.

A lot of computer usage involves dealing with files like videos, documents, photos. Unfortunately, for most users sharing (large) files, finding files, synchronizing files between devices and backing up files is far from trivial. To address these issues, we present an alternative for traditional filesystems: CIMPLE. CIMPLE provides a content-centric storage interface with integrated search and sharing capabilities. It also relieves the user of backup and synchronization problems. CIMPLE gives each content item a secure ID and understands content metadata.
