Oracle Global Data Services (Oracle GDS) provides dynamic load balancing, failover, and centralized service management for a set of replicated databases that offer common services. The set of replicated databases can use Oracle Distributed Database architecture, Oracle Real Application Clusters (Oracle RAC) and non-cluster Oracle Databases interconnected through Oracle Data Guard, Oracle GoldenGate, and Oracle True Cache.
Automate failover during unplanned events and transparently maintain availability during planned maintenance by automatically rerouting traffic.
Minimize latency and maximize the use of available resources by distributing database workloads using intelligent load balancing and dynamic routing.
Reduce administrative overhead by automating complex tasks such as connection routing, failover, and service management.
Seamlessly expand across regions while allowing data to be stored and accessed locally to help meet regulatory requirements.
Reduce the amount of database infrastructure and software needed by automatically using standby capacity for select Oracle Database workloads
GDS centrally manages service configurations and workloads by dynamic service placement and connection distribution across replicated databases for continuous availability and efficient load balancing.
GDS ensures high availability by automatically redirecting connections to replicas during outages using Fast Application Notification (FAN), Fast Connection Failover (FCF) and Transparent Application Continuity (TAC).
GDS enables plug and play database architectures and global scalability while ensuring data sovereignty by routing services to region-specific databases to comply with regulations (*Oracle GDS Guide*, 19c, Section 4.2.2).
GDS optimizes performance by dynamically balancing workloads across replicated databases to minimize bottlenecks and maximize resource use.
GDS simplifies management with GDSCTL, allowing DBAs to configure, operate, and monitor “always on database services from a single interface.
