How to make azure service fabric cluster highly available (cross-region)?

Question

As part of operational readiness we need to ensure that our applications have HA and DR features.

There is official documentation suggesting 2 options - run separate SF clusters or run a standalone cluster.

How to approach the former? What can be done to replicate the state from one cluster to another?

Thanks

To make an Azure Service Fabric cluster highly available across regions, you can follow these steps:

1. Deploy the Service Fabric cluster to multiple Azure regions: To make the cluster highly available, you need to deploy it to at least two Azure regions. This ensures that if one region goes down, the cluster can still operate from the other region.
2. Configure virtual network peering between the regions: To enable communication between the cluster nodes in different regions, you need to configure virtual network peering between the regions. This allows the nodes to communicate with each other as if they were on the same network.
3. Configure load balancing: To distribute traffic across the regions, you need to configure load balancing. You can use Azure Traffic Manager or a similar tool to distribute traffic based on the location of the user or the health of the cluster nodes.
4. Configure replication for data storage: To ensure that data is replicated across the regions, you need to configure replication for the data storage used by the cluster. This can be done using Azure Storage replication or a similar tool.
5. Monitor the cluster for health and performance: To ensure that the cluster is operating correctly and to detect issues as soon as possible, you need to monitor the cluster for health and performance. You can use Azure Monitor or a similar tool to monitor the cluster nodes, data storage, and load balancing.

By following these steps, you can make your Azure Service Fabric cluster highly available across regions, ensuring that your applications remain available even if one region experiences an outage.
