Orchestrator is a replication topology manager for MySQL.

It has many great features:

The topology and status of the replication tree is automatically detected and monitored
Either a GUI, CLI or API can be used to check the status and perform operations
Supports automatic failover of the master, and the replication tree can be fixed when servers in the tree fail – either manually or automatically
It is not dependent on any specific version or flavor of MySQL MySQL, Percona Server, MariaDB or even MaxScale binlog servers
Orchestrator supports many different types of topologies, from a single master - slave to complex multi-layered replication trees consisting of hundreds of servers
Orchestrator can make topology changes and will do so based on the state at that moment; it does not require a configuration to be defined with what corresponds to the database topology
Tone of the cooler things you can do is change replication just by doing a drag and drop in the web interface of course you can do this and much more through the CLI and API as well
