Which solution will meet these requirements?
Use the compute optimized instance family for the application. Use the memory optimized instance family for the database.
Use the storage optimized instance family for both the application and the database.
Use the memory optimized instance family for both the application and the database.
Use the high performance computing (HPC) optimized instance family for the application. Use the memory optimized instance family for the database.
Explanations:
The compute optimized instance family is suitable for compute-intensive workloads, not for memory-heavy workloads like SAP databases. The memory optimized instance family should be used for the database, but compute optimization is not ideal for SAP applications with high memory utilization.
The storage optimized instance family is designed for workloads requiring high, sequential read and write throughput, which is not the primary requirement for SAP applications or databases. Both the application and database require high memory capacity, not primarily storage optimizations.
Memory optimized instances are specifically designed for workloads with high memory requirements. Both the SAP application and the SQL Server database have high memory utilization, so the memory optimized instance family is the best choice for both.
HPC optimized instances are designed for workloads that require high computational power, such as scientific simulations, not for SAP applications or databases, which primarily need memory optimization. Therefore, HPC is not suitable for either the application or the database.
It seems to me that the answer is:
Use the memory optimized instance family for both the application and the database.
