Redundancy and high availability are the basis for all production deployments. With MongoDB this can be achieved by deploying replica set. In this talk we'll explore how MongoDB replication works and what are the components of a replica set. Using examples of wrong deployment configurations, we will highlight how to properly run replica sets in production, whether it comes to on-premise deployment or in the cloud.
