What does a $500K microservices migration really cost?

Around $250-300K in engineer time for small teams, plus $5-10K/month ops—way more than flags and replicas.

Should startups stick with monoliths?

Yes, until 50+ engineers and real scaling pains; fix symptoms first.

Are feature flags enough for safe deploys?

Absolutely—daily rolls, instant rollbacks, no outage trauma.
