HA and DR configurations in Azure - Windows

InfoScale Enterprise lets you configure applications for high availability (HA) and disaster recovery (DR) in Azure cloud environment.

For more information on the supported use cases, read the following topics:

InfoScale Enterprise provides the following agents to manage Azure resources:

  • The AzureIP agent and the AzureDNSZone agent manage the network resources for cluster communication, failover, and failback. These agents monitor and manage the IP resources within cluster nodes in the Azure cloud.

  • The following options are available for handling authentication for Azure subscription:

    • You can configure the AzureAuth agent to use the service principal credentials for authentication. The AzureIP, AzureDNSZone, and the AzureDisk agents then depend on the AzureAuth agent for handling the Azure related authentication.

    • You can also use the Azure user-assigned managed identities for authentication. You can configure the ManagedIdentityClientID attribute for the AzureIP, AzureDNSZone, and the AzureDisk agents to use managed identities for the Azure related authentication.

      In this case, these agents no longer depend on the AzureAuth agent; you do not have to configure the AzureAuth agent resources in the cluster.

      Note:

      Acrtera recommends that you configure the agents to use managed identities, instead of the AzureAuth agent, for authenticating the Azure subscription.

  • In an Azure environment, application data is stored on the Azure data disks that are attached to the Azure virtual machines. The AzureDisk agent provides high availability of the Azure disks during an application failover. This agent supports high availability for managed and unmanaged disks.

    For more information about the agents, refer to the Cluster Server Bundled Agents Reference Guide - Windows.

Note:

Azure recommends that you configure Azure VMs in the same Availability Set to ensure that at least one node from the cluster is always operational.

VCS lets you configure replication between Azure virtual machines, which is further used to support various HA and DR scenarios for applications in Azure cloud.

For more information on the supported replication configurations in Azure, refer to the following documents:

  • Cluster Server Administrator's Guide - Windows

  • Volume Replicator Administrator's Guide - Windows
