What strategies can I employ to minimize CloudFront DDoS costs?

Several strategies can help: 1) Use AWS Shield Advanced for enhanced protection and cost protection. 2) Implement AWS WAF with carefully crafted rules to block malicious traffic efficiently. 3) Optimize your CloudFront cache settings to reduce origin requests. 4) Consider using a CDN provider with built-in DDoS mitigation and potentially more predictable pricing. 5) Implement rate limiting to restrict the number of requests from a single IP address. 6) Regularly review your CloudFront logs to identify and block malicious traffic patterns.
