Question 66 of 100 | ← Chapter 14

Q1066. A company is planning to migrate a TCP-based application into the company's VPC. The application is publicly accessible on a nonstandard TCP port through a hardware appliance in the company's data center.This public endpoint can process up to 3 million requests per second with low latency. The company requires the same level of performance for the new public endpoint in AWS.What should a solutions architect recommend to meet this requirement?

Correct Answer: A. Deploy a Network Load Balancer (NLB). Configure the NLB to be publicly accessible over the TCP port that the application requires.

Explanation

To meet the requirement for migrating a TCP-based application with a high request rate and low latency, the best recommendation is:A. Deploy a Network Load Balancer (NLB). Configure the NLB to be publicly accessible over the TCP port that the application requires.Explanation:- Network Load Balancer (NLB): NLB is designed to handle millions of requests per second while maintaining ultra-low latencies. It operates at the connection level (Layer 4) and supports TCP traffic, making it well-suited for applications requiring high performance on nonstandard TCP ports.Other Options:- B. Deploy an Application Load Balancer (ALB): ALBs operate at Layer 7 and are primarily designed for HTTP/HTTPS traffic. They are not ideal for TCP-based applications needing nonstandard ports and high throughput.- C. Deploy an Amazon CloudFront distribution: CloudFront is primarily a content delivery network (CDN) and is not optimized for handling TCP-based applications in the same way as an NLB. It also adds complexity and may not meet the low latency requirements.- D. Deploy an Amazon API Gateway API: API Gateway is designed for HTTP APIs and may not be suitable for handling high-throughput TCP traffic. It also introduces additional latency and overhead for non- HTTP protocols.Conclusion:Option A is the most suitable choice, as it directly addresses the performance, low latency, and TCP-based requirements for the application in the VPC.
