# Instance Data Replication

The Instance Data Replication \(IDR\) copies data updates from one instance, called the producer instance, to one or more other instances called the consumer instances.

## Active Producer Replication Sets

The Active Producer Replication Sets monitor your producer replication set status and report the data lag time between your instance and the replication queue.

## Active Consumer Replication Sets

Active Consumer Replication Sets monitor your consumer replication set status, report the network lag time, and report the data lag time between the producer instance and consumer instance.
