The new graph database Amazon Neptune is offered as an AWS cloud solution. It supports open graph APIs for Gremlin and SPARQL, and provides high performance for both graph models and their query languages. It also supports read replicas, point-in-time recovery, continuous backup to Amazon S3, and replication across Availability Zones (AZ). It's optimized for processing graph queries and supports up to 15 low latency read replicas across three Availability Zones to scale read capacity and execute several graph queries per second. Neptune continuously backs up data to Amazon S3, and transparently recovers from physical storage failures.
