An architect must compare an on-premises SAP system with candidate EC2 sizes. Which unit provides a hardware-independent performance comparison?
Show answer and explanation
Answer: C
SAPS is the standardized throughput unit derived from SAP standard application benchmarks. AWS publishes SAPS ratings for certified EC2 instance types, and SAP EarlyWatch or Quick Sizer output can be expressed in SAPS, so the two sides can be compared directly. User counts, data volume, and module counts are inputs to sizing but do not describe delivered throughput.
Why the other options are wrong
- A. Concurrent users vary by workload and think time and do not measure the capacity of a server.
- B. Database size drives memory and storage sizing but says little about CPU throughput.
- D. The number of modules describes functional scope, not hardware performance.
Exam tip. Compare SAP hardware with SAPS, not vCPU counts or user counts.
