Amazon Neptune allows you to store relationships between information such as customer interests, friends, and purchase history in a graph and quickly query it to make recommendations that are personalized and relevant. For example, with Neptune you can use a highly available graph database to make product recommendations to a user based on which products are purchased by others who follow the same sport and have similar purchase history. Or, you can identify people that have a friend in common, but don’t yet know each other, and make a friendship recommendation.

With Amazon Neptune, you can use relationships to process financial and purchase transactions in near real time to easily detect fraud patterns. Neptune provides a fully managed service to execute fast graph queries to detect that a potential purchaser is using the same email address and credit card as a known fraud case. If you are building a retail fraud detection application, Neptune can help you build graph queries to easily detect relationship patterns like multiple people associated with a personal email address, or multiple people sharing the same IP address but residing in different physical addresses.

Amazon Neptune helps you build knowledge graph applications. A knowledge graph allows you to store information in a graph model and use graph queries to enable your users to easily navigate highly connected datasets. Neptune supports open source and open standard APIs to allow you to quickly leverage existing information resources to build your knowledge graphs and host them on a fully managed service. For example, if a user is interested in The Mona Lisa, you can also help them discover other works of art by Leonardo da Vinci, or other works of art located in The Louvre. Using a knowledge graph, you can add topical information to product catalogs, build and query complex models of regulatory rules, or model general information, like Wikidata.

Amazon Neptune helps you build applications that store and navigate information in the life sciences, and process sensitive data easily using encryption at rest. For example, you can use Neptune to store models of disease and gene interactions, and search for graph patterns within protein pathways to find other genes that may be associated with a disease. You can model chemical compounds as a graph and query for patterns in molecular structures. Neptune also helps you integrate information to tackle challenges in healthcare and life sciences research. You can use Neptune to create and store data across different systems and topically organize research publications to quickly find relevant information.

You can use Amazon Neptune to store a graph of your network and use graph queries to answer questions like how many hosts are running a specific application. Neptune can store and process billions of events to manage and secure your network. If you detect an event that is an anomaly, you can use Neptune to quickly understand how it might affect your network by querying for a graph pattern using the attributes of the event. You can query Neptune to find other hosts or devices that may be compromised. For example, if you detect a malicious file on a host, Neptune can help you to find the connections between the hosts that spread the malicious file, and enable you to trace it to the original host that downloaded it.
