Keycloak High Availability deployment

[Kishore Guduru]

Hi,

Please advise my application deployment in AWS cloud with keycloak.

1. Looking for Keycloak High Availability and Disaster Recovery solution across AWS regions.

2. Is it possible to deploy multiple keycloak instances in on-premises and sync with cloud deployment. How ?

[Alexander Schwartz]

Hi Kishore,

The short answer is: there is no official documentation for this: The latencies between regions don't allow synchronous replication. And we don't have a blueprint for a database which supports multi-region support. 

It could still be a starting point and you could contribute your results back to those documents. 

Best,

Alexander

Thank you Alexander for your response.

This document shows the HA is within a single region. Can I implement the HA across regions? My requirement is also to deploy Keycloak on-premises ( multiple) and sync with the cloud. Is it possible and How.

Appreciate if you could guide me on this.

Thanks,

Kishore.

Hi Kishore,

The latest Keycloak 23 release includes documentation on how to setup high-availability. Have a look at the link here to get started: https://github.com/keycloak/keycloak/discussions/25269

The setup we describe there requires a low latency between different Keycloak deployments using Mutli-AZ, and I assume your setup would have a higher latency, so your setup would need to look different if you're looking for different regions.

Best,

Alexander
