Global Data Services Region

Use Global Data Services regions to group databases and clients with low-latency communication and ensure high availability in distributed environments.

A Global Data Services region (GDS region) is a named subset of databases in a GDS configuration and database clients that share network proximity with that configuraiton. Network latency between members of a region is typically lower than between members of different regions.

A region usually corresponds to a local area network (LAN) or metropolitan area network (MAN). For example, a data center hosting one or more GDS configuration databases and database clients in geographical proximity can be considered a single region.

A region can contain multiple Global Data Services pools, and a pool can also span multiple regions.

For high availability, each region in a GDS configuration should have a designated buddy region. A buddy region is a region that contains Global Service Managers (GSMs) to provide continued access to the GDS configuration if the Global Service Managers in the local region become unavailable.
