• Cost Optimised HA/DR• PI assumed in DMZ for interfaces• SLT will be used for replicating
data from SAP and non-SAP Sources
• Gateway/Fiori server required due to additional SAP UI5 development

• Use of MDC/MCOS to reduce TCO with SLT and B.Obj (Shared workload)
• B.Obj used for reporting directly from S4
