Amazon Route 53 Resolver DNS Firewall significantly reduces service cost

Over the course of March 2022, Amazon is reducing the cost of using the Amazon Route 53 Resolver DNS Firewall in all regions. First, Amazon is launching new tiered pricing effective March 1 that provides for reduced query processing fees as your query volume increases. Secondly, Amazon is implementing internal optimizations to reduce the number of DNS queries for which you are charged. Note that these optimizations will not reduce the number of DNS queries that are inspected or introduce any other changes to your security posture. Amazon customers will see these cost reductions automatically reflected in their Route 53 bills going forward. To learn more, please visit the Amazon Route 53 pricing page.
