Aiven services and Kafka¶

Aiven is a third party service provider that nais uses for some of the features we provide. If the tenant wishes to use some of those features, Aiven needs to be enabled for the tenant. The tenant does not need to have any interaction with Aiven directly, but the NAIS team will need to set up the necessary resources.

Aiven provides these services:

Kafka (one per tenant environment)
OpenSearch (Created on-demand for each application)
Redis (Created on-demand for each application)

This is an optional feature that is not enabled by default.

For Tenant¶

Requirements and Setup¶

No preparation is required from the tenant.

Usage by Applications¶

Applications that wishes to use Kafka must configure the application:

spec:
  kafka:
    pool: <tenant>-<environment>

Relevant documentation for applications:

For NAIS¶
