Replication from on-premises to AWS - Linux

In this scenario, data is replicated from an on-premises data center to a cloud data center.

Sample configuration

This sample configuration assumes a clustered environment that uses CVR for replication.

  • The primary site is configured on premise.

  • The secondary site is configured on the cloud.

  • Private IP addresses used for replication in standalone environments OR

    Virtual private IP addresses used for replication in clustered environments.

  • A customer gateway on premise and a virtual private gateway on the cloud

  • 2 VPN tunnels connecting the customer gateway and the virtual private gateway. This provides increased availability for the Amazon VPC service. If there's a device failure within AWS, the VPN connection automatically fails over to the second tunnel to provide uninterrupted access.

  • 2 routers connecting the customer and cloud networks.

The following graphic illustrates the configuration.

Sample replication configuration from on-premises to AWS
Prerequisites

Ensure that the following requirements are met before you proceed with the configuration:

  • Open ports for the communication between on premise and AWS cloud clusters in those subnets where the primary and secondary clusters are configured.

    Make sure that in cluster configuration, ports are enabled in the security groups so that the VMs can communicate with each others.

  • The virtual private IP addresses must be plumbed on both master nodes.

  • The virtual private IP addresses must be configured within the subnet.

Setting up replication

The following procedure lists high-level tasks to configure replication from an on-premises data center to a cloud data center in a clustered environment that uses CVR.

To set up replication from on-premises to AWS

  1. Create a VPC with a valid CIDR block, for example 10.239.0.0/16.
  2. Add a subnet in the Availability Zone.
  3. Create the EC2 instance.
  4. Configure the virtual private gateway and attach it to the VPC.
  5. Configure the customer gateway.
  6. Create route table entries.
  7. Associate the subnet with the route table.
  8. Enable route propagation to automatically propagate the routes to the table.

    On the Route Propagation tab in the details pane, choose Edit, select the virtual private gateway that you created.

  9. Create a VPN connection.
  10. Download the VPN configuration file.
  11. Create a VPN tunnel between the customer network and the cloud network.
  12. Set up replication between the on-premise and cloud instances.

    For instructions, see the Setting up replication chapter in the Veritas InfoScale Replication Administrator's Guide - Linux.

  13. Verify the status of replication.
    # vradmin -g dg_name repstatus rvg_name

    Ensure that the replication status shows:
