Resumé: The Regal group of INRIA and LIP6 studies distributed systems and operating systems. Our aim is to design systems that are better by some pragmatic, objective metric: e.g., scalability, response time, throughput, fault tolerance, etc. This requires studying algorithms, understanding their bottlenecks, and improving their design. For instance, we recently showed how to completely remove the consistency bottleneck (in some restricted cases) with the concept of a Conflict-Free Replicated Data Type (CRDT) [SSS 2011]. Cloud computing platforms are evolving towards a hybrid, so-called “fog” model. On the one hand, modern protocols support strong consistency and transactions at the scale of a single or geo-replicated data centres. On the other hand, data is moving outside of data centres, using computing and storage resources near the edge. This enables a wide range of options: an application at the edge can be highly responsive and available, but consistency and fault-tolerance are hard; conversely, a data centre has greater, more elastic computing resources and can more guarantee strong consistency and integrity.
