Remedying Single Points of Failure in the Stack

We can now turn our attention to the actual problem areas inherent in our particular SAP Solution Stack, and ultimately to the mySAP solution being deployed. Single points of failure (SPOFs) potentially exist throughout the SAP Solution Stack and the SAP system landscape in general. We will walk through each layer in the stack next, grouped into six key areas as shown in Figure 6.4. We also look at both general and layer-specific high-availability and disaster recovery offerings as well, noting advantages and disadvantages of each as we move through the simplified stack.
