Resolution

Customers of Red Hat OpenShift Service on AWS and Red Hat OpenShift Dedicated are not affected by this EC2 Classic, Classic Load Balancer deprecation, as it only affects EC2-Classic instances without a VPC.

Customers of ROSA and OSD don't need to take any action as all ROSA and OSD instances use a VPC and use modern EC2.

For reference:

Root Cause

AWS is retiring EC2-Classic on August 15, 2022.

Diagnostic Steps

To see that the region where the cluster is installed does not have EC2-classic functionality, query for classic link instances, using the aws CLI in the same region as the cluster:

$ aws ec2 describe-classic-link-instances

An error occurred (UnsupportedOperation) when calling the DescribeClassicLinkInstances operation: The functionality you requested is not available in this region.

The above message indicates that it is not EC2-Classic.
