Which AWS service provides a highly available, scalable DNS service for applications running on AWS?

Amazon Route 53 is a highly available and scalable cloud Domain Name System (DNS) web service. It translates human-readable domain names (like example.com) into the IP addresses that computers use to connect to each other, making it essential for directing traffic to your applications. It's designed for high availability and integrates seamlessly with other AWS services. Amazon Lightsail is a virtual private server (VPS) provider, offering simplified compute, storage, and networking, but it's not primarily a DNS service. AWS Amplify Hosting is a fully managed service for hosting modern web applications, focusing on deployment and content delivery, not DNS resolution. Amazon S3 (Simple Storage Service) is an object storage service, used for storing and retrieving data, and does not provide DNS functionality.
