Fauna offers several features that distinguish it from DynamoDB, including geo-distribution by default, transactionality with ACID guarantees and global distribution, streaming capabilities with a simple API endpoint, robust security models with API keys and identity-based access tokens, automated functionalities such as database provisioning, maintenance, sharding, scaling, and replication, scalability and pricing on-demand without manual intervention. Fauna is well-suited for organizations that require maximum consistency, high performance, and low latency in their serverless databases. Its "zero ops" model allows developers to focus on building critical aspects of applications while minimizing complexity, leading to a shorter development time and faster application delivery.
