Question
A company is implementing a new application on AWS. The company will run the application on multiple Amazon EC2 instances across multiple Availability Zones within multiple AWS Regions. The application will be available through the internet. Users will access the application from around the world.
The company wants to ensure that each user who accesses the application is sent to the EC2 instances that are closest to the user’s location.
Which solution will meet these requirements?
A. Implement an Amazon Route 53 geolocation routing policy. Use an internet-facing Application Load Balancer to distribute the traffic across all Availability Zones within the same Region.
B. Implement an Amazon Route 53 geoproximity routing policy. Use an internet-facing Network Load Balancer to distribute the traffic across all Availability Zones within the same Region.
C. Implement an Amazon Route 53 multivalue answer routing policy. Use an internet-facing Application Load Balancer to distribute the traffic across all Availability Zones within the same Region.
D. Implement an Amazon Route 53 weighted routing policy. Use an internet-facing Network Load Balancer to distribute the traffic across all Availability Zones within the same Region.
Answer
A. Implement an Amazon Route 53 geolocation routing policy. Use an internet-facing Application Load Balancer to distribute the traffic across all Availability Zones within the same Region.
Explanation
- Amazon Route 53 geolocation routing policy allows you to direct traffic based on the geographic location of your users. This ensures that users are routed to the EC2 instances closest to their location, minimizing latency and improving user experience.
- An internet-facing Application Load Balancer (ALB) is the appropriate choice for distributing traffic across EC2 instances within the same Region. ALB operates at the application layer (Layer 7) and provides advanced routing capabilities, such as path-based routing and host-based routing.
- Option B is incorrect because a Network Load Balancer (NLB) is not the best fit for this scenario. NLBs operate at the transport layer (Layer 4) and are better suited for handling high-performance TCP traffic.
- Option C is incorrect because a multivalue answer routing policy is used to return multiple values, such as IP addresses, in response to DNS queries. It does not consider the geographic location of users.
- Option D is incorrect because a weighted routing policy is used to distribute traffic across multiple resources based on predefined weights. It does not take into account the geographic proximity of users to EC2 instances.
By implementing an Amazon Route 53 geolocation routing policy and using an internet-facing Application Load Balancer, the company can ensure that each user who accesses the application is directed to the EC2 instances closest to their location, regardless of the AWS Region.
