But being able to freely/quicly stand up database servers and quickly create/drop databases makes development and testing much simpler and more reliable.

Given the question: "How do you know that deploying this thing will work?"

- When it's quick/legal to stand up fresh servers and create databases, the answer can be "I tested it, just now, and it works." - Otherwise you end up in "I read through it and it looks good" or perhaps "We tried most of it on the test instance last week before the other team started using it."

I much prefer the former.
