"Camunda 8, Setting up High Availability on k8s Cluster

Hello, we are using Camunda 8 on a k8s cluster (OKD).
Could you please provide guidance on the following questions:

Is it advisable to have 2 or more nodes for camunda-elasticsearch?
Is it possible and reasonable to back up Elasticsearch, in cases where k8s (OKD) is recovered after a failure?
Are there any recommendations for ensuring high availability (some best practices)?

Best regards.

Why is there no answer from the Camunda staff for such an important question? Seems like Camunda 8 is not supported at all in the forums.

@Nikos_M - this is a community forum, not an official support channel. There have been significant changes to the documentation in the last 25 months, so I would recommend checking that out, as it answers these questions. However, some clarifications may needed based on your individual environment and needs, and we usually recommend working with our support team for those.
