If you are interested in your choices for HA/DR and S/4HANA, I encourage you to attend a free webinar Dec 8, presented with SUSE. We will look at the major choices you have, see how HANA runs on the SUSE Linux Enterprise High Availability Enterprise Cluster, and discuss best practices.
This is a good use of time for those who are interested in S/4HANA (or any other HANA-based solution) but want to know a bit more about real-world deployment details.
The webinar will be run twice on Dec 8, for both Europe and NA time zones:
4pm CET: Event Registration
