Kline: The main difference is that you cannot perform the same sort of adjustments to the Windows OS-level settings in RDS than compared to on-prem since RDS manages all of that for you. Because of that, it’s important to focus your attention on the things that you can troubleshoot, such as database indexing choices and SQL code. That’s where the SentryOne products excel – DB Sentry for instances of RDS and Plan Explorer for tuning queries.
