Amazon Route 53 is the AWS feature designed for scalable and cost-effective routing of end users to Internet applications. It acts as a Domain Name System (DNS) web service, allowing users to direct traffic to various resources, such as web applications across multiple regions or cloud resources, in a highly available and reliable manner.

One of the core functions of Route 53 is to manage domain names and route end users to the appropriate resources based on a number of factors like latency and location. By intelligently directing user requests, Route 53 optimizes the performance of applications and ensures high availability. It also integrates well with other AWS services, allowing for seamless routing and load balancing, enhancing the user experience.

In contrast, AWS Lambda is a serverless compute service that executes code in response to events, and isn’t focused on routing or DNS capabilities. Amazon S3 is an object storage service for storing data, not for routing or managing domain names. AWS Global Accelerator, while it provides network optimization and improves the availability and performance of applications, focuses on directing traffic through the AWS global network rather than managing domain names and DNS responses directly. Route 53 thus more specifically addresses the requirement of routing users to applications over the Internet.
