NetApp Exam NS0-304 Topic 1 Question 21 Discussion

To enable replication traffic between two instances of Cloud Volumes ONTAP (CVO) deployed in Azure and AWS, a Virtual Private Network (VPN) must be configured. This setup is crucial because it provides a secure and private communication channel over the internet, which is necessary for the replication of data between different cloud providers. Here's the process:

Setup VPN Connection: Establish a VPN connection between the Azure and AWS environments. This involves configuring VPN gateways in both clouds to enable encrypted traffic flow between the two instances of CVO.

Configure Network Routing: Ensure that the routing rules are set to direct the replication traffic through the VPN connection. This might include setting up appropriate route tables that point to the VPN gateway.

Test and Verify Connectivity: After setting up the VPN, conduct tests to verify that the replication traffic is flowing correctly and securely between the two cloud environments.

Using a VPN is the most straightforward and typically the most cost-effective method to securely link AWS and Azure for the purpose of data replication, without the need for direct connectivity services like AWS Direct Connect or Azure ExpressRoute, which are more complex and costly solutions.

For guidance on setting up VPNs between AWS and Azure, refer to the respective cloud provider's documentation on VPN configuration.
