Question
A company has an online gaming application that has TCP and UDP multiplayer gaming capabilities. The company uses Amazon Route 53 to point the application traffic to multiple Network Load Balancers (NLBs) in different AWS Regions. The company needs to improve application performance and decrease latency for the online game in preparation for user growth.
Which solution will meet these requirements?
A. Add an Amazon CloudFront distribution in front of the NLBs. Increase the Cache-Control max-age parameter.
B. Replace the NLBs with Application Load Balancers (ALBs). Configure Route 53 to use latency-based routing.
C. Add AWS Global Accelerator in front of the NLBs. Configure a Global Accelerator endpoint to use the correct listener ports.
D. Add an Amazon API Gateway endpoint behind the NLBs. Enable API caching. Override method caching for the different stages.
Answer
C. Add AWS Global Accelerator in front of the NLBs. Configure a Global Accelerator endpoint to use the correct listener ports.
Explanation
AWS Global Accelerator is a networking service that provides static IP addresses that act as a globally distributed entry point to your applications hosted on AWS. It optimizes the path from users to your applications, improving performance and reducing latency.
By adding AWS Global Accelerator in front of the Network Load Balancers (NLBs), the solution addresses the company’s requirements:
- Improve application performance:
- Global Accelerator uses AWS’s internal network to optimize the path from users to the application, reducing internet latencies and improving performance.
- It intelligently routes traffic to the nearest AWS Region based on network conditions, ensuring users are connected to the closest application endpoint.
- Decrease latency for the online game:
- Global Accelerator continuously monitors the network path from every AWS Edge Location to your application, making intelligent routing decisions to the optimal endpoint.
- This minimizes latency and provides a consistent, high-performance experience for users globally.
- Accommodate user growth:
- Global Accelerator can handle massive amounts of traffic and automatically scales to meet demand, ensuring the application can scale seamlessly as the user base grows.
To enable Global Accelerator for the online gaming application, you need to configure a Global Accelerator endpoint for each NLB, specifying the correct listener ports for TCP and UDP traffic used by the game.
Other options:
A. Using Amazon CloudFront and increasing the Cache-Control max-age parameter is not suitable for real-time multiplayer gaming applications that require low latency and do not benefit from caching.
B. Replacing NLBs with Application Load Balancers (ALBs) and using Route 53 latency-based routing would not provide the same level of performance optimization and latency reduction as Global Accelerator.
D. Adding an Amazon API Gateway endpoint behind the NLBs and enabling caching is not applicable for a real-time multiplayer gaming application that requires low latency and does not use APIs.
