8.8 AWS Networking Guidelines

Consider the following guidelines when you are migrate workloads to AWS:

8.8.1 Private and Public IP Addresses for Workloads Connected on an AWS VPN

Each AWS VM has both a public IP address and a private IP address for communications from machines outside the AWS environment. AWS automatically associates these IP addresses with the primary network interface for the VM.

AWS provides public IP addresses for the target instance only in case of workloads with single NIC. For workloads with multiple NICs, AWS provides only private IP addresses for the target instance and so you can connect to the target instance using only the private IP addresses. If the UseOnlyPublicIPForAWS PlateSpin Configuration parameter is set to True and you choose to migrate a source workload with multiple NICs, then you must include only one NIC for migration when you configure the migration job.

You can use the Microsoft Remote Desktop client or SSH to remotely connect to the AWS VM. Specify the IP address as follows:

  • Private IP address: Use the VM’s private IP address if your machine is part of the address space for the AWS VPN.

  • Public IP address: Use the VM’s public IP address if your machine is not part of the address space for the AWS VPN. A public IP address is not set on the target workload that has multiple NICs.
