As your PE-managed infrastructure grows, moving to a larger AWS instance type improves your system performance.
The PE AMI is EBS-backed and hardware virtualized (HVM), so the resizing process doesn't require reconfiguration of PE services. Follow the AWS instructions for Resizing an EBS-backed instance.
During EC2 resizing, your instance's public hostname and IP address might change. To access the PE console, connect to the new public hostname. Resizing the instance doesn't change the internal (private) hostname or IP address, and therefore no change is required for PE services or managed nodes. See the Certificates and DNS configuration section for more information.
