A less clickbait-y title would be, "How to Run Our Database on AWS at a Reasonable Cost".
"Reasonable Cost" comes from the conclusion, and I omitted "Better Performance" since they never compare to alternatives (although they do mention Aurora).

I understand the desire to "reel in" more readers than a post might otherwise warrant, but in my experience you're better off not promising general advice if you're not providing it.
For example, you might say, "How we configure TiDB on AWS to handle XXX transactions per second for XXX/month", or "Squeezing the highest TiDB performance from AWS m5 instances". There are definitely interesting ways to title posts in a way that's supported by the content.
