Oracle Global Data Services (GDS) is a feature of Oracle Database 12c that provides connect-time and run-time load balancing, region affinity, replication lag tolerance based workload routing, and enables inter-database service failover over a set of replicated databases. GDS maximizes performance and availability of the applications and it allows database workloads to be managed across distributed replicas with a single unified framework.
