How do I handle site performance during flash sales?

I'm running an e-commerce store and I'm concerned about how our website will handle sudden traffic spikes during flash sales. In the past, we've experienced slow loading times, site crashes, and frustrated customers when we run high-traffic promotional events. I need a comprehensive strategy to ensure our site remains stable, fast, and user-friendly during these critical revenue-generating moments. What technical and operational steps can I take to optimize site performance and prevent potential sales loss during flash sales?
