Globally Distributed Autonomous Database

Oracle Globally Distributed Autonomous Database is a fully automated distributed cloud database that helps customers meet data residency requirements, provide survivability for business-critical applications, and deliver cloud-scale database performance.

Support a global user base with a fully automated distributed database

See how Globally Distributed Autonomous Database can help you succeed.

Address data residency requirements by controlling where data resides.

Provide high availability by distributing shards across OCI availability domains and regions.

Enable cloud scale and performance by automatically scaling the number of shards and their individual performance.

Develop distributed database applications and efficiently manage them as a single logical database with no changes required.

Automatically distribute and redistribute data based on performance needs and location.

Use Oracle Autonomous Database Select AI to query distributed data using natural language without knowing where it is or how it’s structured.

How it works

Globally Distributed Autonomous Database is a single logical Oracle Database that is distributed as a set of Oracle Database shards. Each shard is an independent Oracle Database instance that hosts a subset of the logical database's data. Multiple shards can run in one OCI availability domain to maximize performance, in multiple OCI availability domains or regions to provide the highest possible availability, and in OCI regions across different geographies to help meet data residency requirements.

A common shard catalog supports automated shard deployment, centralized management of a sharded database, and multi-shard queries using the automated query coordinator. Shard directors enable high performance connection routing over networks to access data in a distributed database. A client application request is routed directly to a shard using the Oracle drivers and provides a sharding key with the request.

Oracle Globally Distributed Autonomous Database enables transactional or data warehousing applications to access a distributed autonomous database.

The database is divided into multiple physically independent shards, which can all be placed in one OCI region or different regions.

An application interfaces with a shard director, which provides automated connection routing between shards and is transparent to users.

A shard catalog supports automated shard deployment and centralized management of a distributed database across regions. It also supports multi-shard queries.

Each shard is replicated with Data Guard for high availability.

Globally Distributed Autonomous Database use cases

  • Address data residency requirements for distributed data warehousing and data lakes

    Combine user control of data distribution policies and built-in automation to keep the storage and processing of growing data sets in required geographical locations while providing centralized administration.

  • Cloud-scale transaction processing

    Improve customer experiences by enabling the database performance needed by cloud-scale applications and locating data close to distributed users—all with automated data distribution and management.

  • Maximum availability for mission-critical applications

    Run applications that require extremely high availability using Globally Distributed Autonomous Database’s shared-nothing architecture and fault-tolerant local Oracle Exadata Cloud Infrastructure.

  • Distributed data pipelines and analytics

    Rapidly load, process, and analyze massive data sets in a distributed cloud while addressing data residency requirements. Get unified insights with massively parallel processing across many compute instances.

  • Query global distributed data using natural language

    Easily gain insights from your data without knowing where it’s located or how it’s structured. Simply ask questions in natural language and let Oracle Autonomous Database Select AI build your queries and present results.

  • Build cloud native, scalable mission-critical applications

    Build scalable, secure, distributed applications using multiple data types and models across a single logical database without the need for additional code or skills.
