In the 3.1 Pre-requisites section of the Chapter 3. Externalizing databases for 2.16. there is the following note:

This guide provides steps for creating the databases within the OpenShift cluster, using the Deployment resource, in a similar way the 3scale operator created the internal databases in versions 2.15 and older. This setup is not recommended for production environment.

The point 3 of the Pre-requistes states:

3. In case the databases will be deployed on the OpenShift cluster, the cluster must have enough resources to be able to create a new PostgreSQL database (in case currently PostgreSQL is used) and 2 additional Redis instances.

• Why the note states "This setup is not recommended for production environment." if the point 3 states that you can deploy databases within the OpenShift cluster? We document how to externalize databases on-cluster in the following chapters:

• • 3.2. PostgreSQL 10 upgrade - On-Cluster
  • 3.3 MySQL migration to external - On-Cluster
  • 3.4 Redis 6 upgrade - On-Cluster

The note is in conflict with the point 3 of the pre-requisites, this is creating confusion for our customers and how to support them. The request is to remove the statement that the setup is not recommended for production environments.
