Amazon Neptune

It provides a fully managed graph database that supports both RDF and property‑graph models, allowing developers to store and query highly connected data without provisioning or maintaining underlying infrastructure. The service can scale automatically to handle large numbers of vertices and edges, offering high query throughput, extensive storage per cluster, and optional read replicas for increased performance.

Built‑in capabilities include algorithms for rapid analysis of billions of relationships, vector search integration for generative AI workloads, and automated GraphRAG support that links graph data with large‑language‑model applications. Security features such as ACID transactions, encryption at rest and in transit, automated backups, cross‑Region replication, and fine‑grained permissions align with enterprise AWS standards.

Typical use cases mentioned are identity and knowledge graphs, fraud detection, customer‑360 profiles, and enhancing AI accuracy and explainability by providing contextual graph data for downstream models. The service is billed on a pay‑as‑you‑go basis with no upfront commitments.
