Architecture
To make Daikoku works, you'll need a Postgres datastore and an emailing provider (Mailgun and Mailjet are supported). You can also export the audit trail of Daikoku using many techniques with webhooks, a Kafka topic or an elastic cluster.
As you can see, Daikoku is capable of working with many Otoroshi cluster instances to handle all the use cases of exposing APIs. Daikoku will never interact directly with your APIs.
