Confidential Computing continues as the emerging area to address data sovereignty and data in use protection. 
On IBM LinuxONE and Linux on IBM Z the underlaying technology IBM Secure Execution is further evolving and new features and capabilities.

While more enterprise use cases are identified it remains key that solution stacks take advantage of this technology and simplify end-to-end usage to foster adoption. This is what the IBM Hyper Protect Platform aims to provide jointly with the support of our partners like SUSE and their SLE BCI Containers library:

Recently the Technical Reference Documentation about has been updated by Mike Friesenegger, Solution Architect at SUSE and Rob Culp published a recent blog with further insight: <link to Rob>

It now covers in further detail how the Crypto Passthrough capability (https://community.ibm.com/community/user/blogs/nicolas-mding/2024/04/29/ibm-secure-execution-for-linux-crypto-support) of IBM Secure Execution can be used with the IBM Hyper Protect Container Runtime image either in IBM Cloud or on premises on a Linux LPAR with SUSE Linux Enterprise Server: https://documentation.suse.com/trd/ibm/html/gs_sles_ibm-hpvs/index.html#id-prepare-ibm-crypto-express-adapters-and-domains-to-be-passed-into-a-containerized-workload
