-The key insight is that the IO capacity of a shared, commodity system is more limited than that of a dedicated server machine. There's a premium on minimizing unnecessary IO to take maximum advantage of the system in the resources of each compute size of the service tiers. Appropriate physical database design choices can significantly improve the latency for individual queries, improve the throughput of concurrent requests handled per scale unit, and minimize the costs required to satisfy the query.
