A company wants to migrate two DNS servers to AWS. The servers host about 200 zones and receive 1 million requests per day on average. The company wants to maximize availability while minimizing operational overhead related to managing the two servers. What should a solutions architect recommend to meet these requirements?

Creating 200 new hosted zones in Amazon Route 53 and importing zone files directly leverages AWS's highly available, managed DNS service. Route 53 is designed for high availability and scalability, inherently minimizing operational overhead compared to managing EC2 instances. It can easily handle millions of requests daily without requiring server maintenance. Launching a single large EC2 instance introduces a single point of failure and requires manual management, failing to maximize availability. Migrating servers with AWS SMS still leaves the operational overhead of managing ECEC2 instances and their underlying DNS software. Launching an EC2 instance in an Auto Scaling group with a desired capacity of 1 still means only one instance is active at a time, and while it offers some recovery, it doesn't match Route 53's inherent availability and managed nature for DNS.
