To all concerned,
We have been notified that AWS has removed the RHEL listings for Micro Focus Vertica from the AWS marketplace overnight in error. We are currently working with AWS to determine the issue, and get the listing reinstated. For customers that have already deployed Micro Focus Vertica on RHEL from the marketplace, AWS states you are unaffected, and can continue spinning up new instances on the RHEL based AMIs. We apologize for this inconvenience, and hope to have it rectified quickly.
