With Barrel, you can easily bring and keep a view (complete or partial) of your data inside your application and replicate it between your different machines. This talk will describe how you can use Barrel to quickly create your own peer-to-peer data platform with different storage and replication strategies. It will also shows the different tools supported by Barrel, to operate and monitor your cluster on premise or on the "cloud". Different examples, codes and patterns will be presented.
