when should you really focus on saving money versus making sure things run fast in the cloud

Hey everyone, I've been thinking a lot about the tradeoffs between optimizing cloud infrastructure for cost versus performance lately. We've hit a point where certain services are becoming really expensive, and I'm wondering how others approach this decision. Are there common metrics or triggers you use to decide when it's time to prioritize cost savings, even if it means a slight performance hit? Or do you generally lean towards always maintaining peak performance? Curious to hear your strategies and experiences.
