InnoDB Cluster is a combination of MySQL technologies which includes Group Replication, MySQL Shell, and MySQL Router. The fault tolerance is indeed using Group Replication under the hood, and MySQL Shell (and the Admin API in particular) simplifies configuration and management. MySQL Router is used for automatically proxying traffic from clients to the appropriate instance.
