Is the Overlay IP CIDR range for SAP on AWS just a secondary CIDR range added to same VPC?
I was reading [the docs on HA configurations for SAP on AWS](https://docs.aws.amazon.com/sap/latest/sap-hana/sap-hana-on-aws-ha-configuration.html), and I see that you need a non-overlapping CIDR range to draw your overlay IP from. Is that just a secondary CIDR range that you need to add to the VPC in which your SAP cluster lives?

FQDN value in strust for SAP Fiori working with Route 53
The customer wants to keep custom FQDN for DEV & QAS when lifting to AWS, and they need to create certs in strust for access via Fiori. In this case, do we put the custom FQDN or Route 53's FQDN when creating the cert in strust? I assume that it should just stay as is, because the connection to the DEV/QAS instances is resolved via private hosted zone of Route 53, where the custom FQDN is registered. Would you help confirm?
