Fauna is a distributed document-relational database delivered as a cloud API. Build new or migrate existing applications to Fauna and scale without worrying about operations. Our document-relational database, distributed globally, is accessible via a secure, cloud API. This architecture provides developers the flexibility and familiarity of JSON documents and the relationships and querying power of a traditional relational database. Developers can also program functions within Fauna to express business logic that is then executed as an ACID transaction in the context of their data — without ever worrying about database provisioning, scaling, sharding, or replication.
