Confidential Computing instance profiles - s390x Gen 2

Deprecated The IBM Z or LinuxONE confidential computing family of 2nd generation virtual server profiles (balanced, compute, and memory) are built atop the s390x processor architecture, with native integration into IBM Cloud® VPC.

The confidential computing profiles enable IBM Secure Execution for Linux. The profiles support the IBM Hyper Protect Container Runtime image.

Limits

An instance has a limit for the number of volumes and virtual network interfaces that can be attached. This limit is based on the size of the instance.
