In May, Red Hat announced the preview of Red Hat OpenShift Service on AWS (ROSA) with hosted control planes (HCP), a new deployment model for ROSA clusters. Today, we are introducing an AWS account configuration workflow for ROSA with HCP on the AWS Management Console. Under the original ROSA deployment model, now called ROSA classic, all AWS infrastructure required to run the ROSA control plane is hosted on your AWS account. Now, you can create ROSA clusters with the control plane hosted and managed on a service account. During the preview, ROSA with HCP clusters will not incur ROSA service fees and should not be used for production workloads.
