-### (fr) Garage, un système de stockage de données géo-distribué léger et robuste
-
-Garage est un système de stockage de données léger, géo-distribué, qui
-implémente le protocole de stockage S3 de Amazon. Garage est destiné
-principalement à l'auto-hébergement sur du matériel courant d'occasion. À ce
-titre, il doit tolérer un grand nombre de pannes: coupures de courant, coupures
-de connexion Internet, pannes de machines, ... Il doit également être facile à
-déployer et à maintenir, afin de pouvoir être facilement utilisé par des
-amateurs ou des petites organisations.
-
-Cette présentation vous proposera un aperçu de Garage et du choix technique
-principal qui rend un système comme Garage possible: le refus d'utiliser des
-algorithmes de consensus, remplacés avantageusement par des méthodes à
-cohérence faible.  Notre modèle est fortement inspiré de la base de donnée
-Dynamo (DeCandia et al, 2007), et fait usage des types de données CRDT (Shapiro
-et al, 2011).  Nous exploreront comment ces méthodes s'appliquent à la
-construction de l'abstraction "stockage objet" dans un système distribué, et
-quelles autres abstractions peuvent ou ne peuvent pas être construites dans ce
-modèle.
-
-### (en) Garage, a lightweight and robust geo-distributed data storage system
-
-Garage is a lightweight geo-distributed data store that implements the Amazon
-S3 object storage protocol.  Garage is meant primarily for self-hosting at home
-on second-hand commodity hardware, meaning it has to tolerate a wide variety of
-failure scenarios such as power cuts, Internet disconnections and machine
-crashes. It also has to be easy to deploy and maintain, so that hobbyists and
-small organizations can use it without trouble. 
-
-This talk will present Garage and the key technical choice that made Garage
-possible: refusing to use consensus algorithms and using instead weak
-consistency methods, with a model that is loosely based on that of the Dynamo
-database (DeCandia et al, 2007) and that makes heavy use of conflict-free
-replicated data types (Shapiro et al, 2011).  We will explore how these methods
-are suited to building the "object store" abstraction in a distributed system,
-and what other abstractions are possible or impossible to build in this model.
