Amazon Neptune Global Database

Amazon Neptune Global Database is designed for globally distributed applications, allowing a single Neptune database to span multiple AWS Regions. It replicates your data with little impact to database performance, enables fast local reads with low latency in each Region, and provides disaster recovery in case of region-wide outages. With Neptune Global Database, you can now deploy a primary Neptune database cluster in one AWS Region, and replicate their data in up to five secondary read-only database clusters (with up to 16 read replicas each) in different AWS Regions.

Global Database uses storage-based replication with typical latency of less than 1 second, using dedicated infrastructure that leaves your database fully available to serve application workloads. In the unlikely event of an AWS Regional degradation or outage, one of the secondary AWS Regions can be promoted to read and write capabilities in a Global Database.

Neptune Global Database Benefits

Sub-Second Data Access in Any Region

Neptune Global Database lets you easily scale database reads across AWS Regions and place your applications close to your users. Your applications enjoy quick data access regardless of the number and location of secondary Regions, with typical cross-Region replication latencies as low as 1 second. You can achieve further scalability by creating up to 16 database instances in each AWS Region, which will all stay continuously up to date. Extending your database to additional Regions has no impact on performance. Cross-Region replication uses dedicated infrastructure in the storage layer, keeping database resources in the primary and secondary Regions fully available to serve application needs.

Cross-Region Disaster Recovery

If your primary Region suffers a performance degradation or outage, you can promote one of the secondary Regions to take read/write responsibilities. A Neptune cluster can recover in less than 1 minute even in the event of a complete Regional outage. This provides your application with an effective Recovery Point Objective (RPO) of 1 second and a Recovery Time Objective (RTO) of less than 1 minute, providing a strong foundation for a global business continuity plan.


With Neptune Global Database, you pay for the resources used in the AWS Regions where your Neptune cluster is present based on the on-demand Neptune instance, and storage prices for that Region. In addition, you pay for replicated write I/Os, which will capture writes, inserts, and deletes between the primary and each secondary cluster. For full pricing and Regional availability see Amazon Neptune Pricing.

Getting started

Get started with Amazon Neptune, a fully managed graph database

Amazon Neptune is a fast, reliable, fully managed graph database service that makes it easy to build and run applications that work with highly connected datasets. The core of Amazon Neptune is a purpose-built, high-performance graph database engine optimized for storing billions of relationships and querying the graph with milliseconds latency. Amazon Neptune supports popular graph models Property Graph and W3C's RDF, and their respective query languages openCypher, Apache TinkerPop Gremlin and SPARQL, allowing you to more easily build queries that efficiently navigate highly connected datasets. Neptune powers graph use cases such as recommendation engines, fraud detection, knowledge graphs, drug discovery, and IT security.
