Replication from on-premises to Azure - Windows

The following diagram illustrates the sample configuration for setting up replication between an on-premises data center to an Azure data center:

Note:

For the ease of use, the machines, whether virtual or physical, are commonly mentioned as virtual machines. Your on-premises data center may include physical machines instead of the virtual machines. In any case, the procedure to set up replication from an on-premises data center to a cloud data center remain the same for physical and well as virtual machines.

About setting up replication between an on-premise data center to on-cloud data center

Replication between an on-premise data center to on-cloud data center involves the following high-level steps:

  1. Prepare the setup at on-premise data center

  2. Prepare the setup at on-cloud data center

  3. Establish a tunnel from on-premise data center to on-cloud data center

  4. Deploy setup

The following sections provide details about performing each of these steps.

Preparing the setup at on-premise data center

To prepare the setup at on-premise data center

  1. Enable the ports that are used for inbound and outbound communication.

    For details, refer to the Veritas InfoScale Installation and Upgrade Guide - Windows.

  2. Create a subnet and a local VPN gateway.
  3. Note the address space that is allotted for the subnet and the public IP address that is allotted for the local VPN gateway.
Preparing the setup at on-cloud data center

To prepare the setup at on-cloud data center

  1. Using Microsoft Azure portal, create a resource group.
  2. Create a VNet in the resource group created and specify an IP address space for the VNet.

    The IP address range must be diff on the on-premise subnet and on the on-cloud subnet.

  3. Create a gateway subnet.
  4. Create a VPN gateway and associate it with the created VNet.

    Note the public IP address that is allotted for the on-cloud VPN gateway.

  5. Create a local network gateway.

    When you create the local network gateway, you must provide the on-premise subnet IP address range and the public IP address of the on-premise local VPN gateway.

  6. Establish a tunnel from on-cloud to on-premise network.

    To establish the tunnel, create a connection of type Site-to-Site (IPSec) and choose the on-cloud VPN gateway and the local network gateway.

  7. Provide a shared key (alpha-numeric key).

    A shared key is a pass-phrase. This pass-phrase is required when you establish a tunnel from on-premise data center to cloud data center.

Establishing a tunnel from on-premise data center to on-cloud data center

To establish a tunnel from on-premise data center to on-cloud data center, use the following parameters:

  • Public IP address that is allotted for the on-cloud VPN gateway

  • Shared key (alpha-numeric key) that was provided while establishing a tunnel from on-cloud data center to on-premise data center

  • On-cloud VPN gateway configuration type (Policy based or Route based)

Deploying the setup

To deploy the setup (in both the data centers)

  1. Create virtual machines in the subnets created.
  2. Provision storage.
  3. Install the appropriate InfoScale product.
  4. Create VxVM disk groups, VxVM volumes, Replicated Volume Group (RVG), and RLinks.
  5. Flush the iptables on both the virtual machines.

    # iptable -F

  6. Set up replication between the virtual machines using the private IP address or the virtual IP address.
  7. Verify the replication status.

    # vradmin -g dg_name repstatus rvg_name

    Ensure that the replication status shows:

    Replication status: replicating (connected)
