Oracle's Globally Distributed Database suite of fully managed Oracle Cloud Infrastructure services provide a single user interface to deploy and manage a data set across many database instances (shards) in a globally distributed, linearly scalable, multimodel database.

Oracle Globally Distributed Autonomous Database brings the power of distributed (sharded) databases to Oracle Autonomous Database on Dedicated Exadata Infrastructure. The service is built on top of Oracle's autonomous technology, which means that it is self-driving, self-securing, and self-healing. This allows automation of many of the routine tasks associated with managing a database, such as patching, tuning, and backup and recovery, which can help reduce the risk of human error and improve system uptime.

Oracle Globally Distributed Exadata Database on Exascale Infrastructure (Distributed ExaDB-XS) brings the power of distributed databases to Oracle Exadata Database on Exascale Infrastructure. The service is built on top of Oracle's Exascale software services technology, which further empowers Exadata to meet the most demanding corporate and cloud computing requirements by decoupling Oracle Database and GI clusters from the underlying Exadata storage servers.
