SUSE is looking to invest into product simplification, especially in High
Availability
— Automated deployment and configuration
• Provide tools and scripts to configure HA stack
— Configuration checks
• Basic check to ensure setup is supported and consistent
• validation before and during production
• At a later stage optimization and tuning recommendation
SAP HA deployments are seen as complicated by clients and partners and represent a
significant part of SAP related support tickets on SAP and SUSE.
Focus areas - SAP High Availability simplification

Container based workloads
• SAP Data Intelligence is validated for SUSE Rancher
RKE
• RKE 1 is validated for SAP Data Intelligence
• RKE2 is underway
• SAP Data intelligence embraces SUSE container
• SUSE contributes to SAP Gardener project
SAP BusinessOne for HANA
• SUSE has updated the “SAP BusinessOne for HANA”
image to SLES 15 SP2
