# Kafka Pools

This is a list of available Kafka pools for [topics](/persistence/kafka/how-to/create.md) and [applications](/persistence/kafka/how-to/access.md).

Topic resources can only be specified in GCP clusters.
Applications can access topics from any cluster, including on-premises.

Use the `nav-dev` pool for development and `nav-prod` for production.
