Explanation
Amazon Neptune is AWS's fully managed graph database service that is specifically designed for graph data models. Here's why it's the correct choice:
-
Graph Database: Amazon Neptune is purpose-built for graph databases, supporting both Property Graph and RDF data models
-
Scalable: Neptune automatically scales storage and can handle billions of relationships with low latency
-
Highly Available: It provides high availability through multi-AZ deployments with automatic failover
-
Managed Service: As a fully managed service, it handles patching, backups, and recovery automatically
Why the other options are incorrect:
-
Amazon Aurora: A relational database compatible with MySQL and PostgreSQL, not a graph database
-
Amazon Redshift: A data warehouse service for analytics and business intelligence, not a graph database
-
Amazon DynamoDB: A NoSQL key-value and document database, not specifically designed for graph data
For graph database requirements involving connected data, relationships, and complex queries, Amazon Neptune is the appropriate AWS service.
