Answer: Amazon Route 53

## Explanation Amazon Route 53 is the correct answer because it is AWS's scalable Domain Name System (DNS) web service that can route users to different endpoints based on geographic location. ### Key Features of Amazon Route 53 for Geographic Routing: 1. **Geolocation Routing Policy**: Route 53 can route traffic based on the geographic location of your users. This allows you to direct users to different website versions based on their country or region. 2. **Latency-based Routing**: While not specifically mentioned in the question, Route 53 can also route traffic based on the lowest network latency for better performance. 3. **DNS-based Solution**: As a DNS service, Route 53 operates at the domain level, making it ideal for directing users to different website versions before they even reach the application servers. ### Why Other Options Are Incorrect: - **AWS Lambda**: A serverless compute service for running code without provisioning servers. It doesn't handle geographic routing of website traffic. - **Amazon Cognito**: A service for user authentication, authorization, and user management. It doesn't handle geographic routing. - **Amazon Lightsail**: A simplified virtual private server (VPS) solution for simple web applications. While it can host websites, it doesn't provide geographic routing capabilities. ### How Route 53 Geographic Routing Works: 1. You create different endpoints (e.g., different website versions for different countries) 2. Configure Route 53 with geolocation routing policies 3. When users access your domain, Route 53 checks their geographic location 4. Based on the location, Route 53 returns the appropriate endpoint IP address 5. Users are directed to the country-specific version of your website This solution is cost-effective, scalable, and integrates well with other AWS services.
