Orchestrator is a replication topology manager for MySQL. Features include: * 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. * The GUI is not only there to report the status - one 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).
