<p>You can use <a href="https://submariner.io/getting-started/architecture/" rel="nofollow noreferrer">Submariner</a> to connect multiple clusters, it creates a secure and performant connection between the clusters on-premises and on public clouds, then you can export the services and access them across all clusters in the cluster set.</p>

<p>Usually we use this tool to create multiple K8S clusters in different geographical locations, then replicate the databases across all the clusters to avoid data loss in case of any data center incident.</p>
