Ra (https://github.com/rabbitmq/ra) is an implementation of the Raft consensus protocol by Team RabbitMQ.

This talks will be a practical session on how to implement consistent distributed system essentials such as replicated a key-value stores, leader election processes, lock servers and other coordination services on top of the Ra library.
