You lead a team to develop a new web application in AWS EC2. The application will have a large number of users globally. For a great user experience, this application requires very low network latency and jitter. If the network speed is not fast enough, you will lose customers. Which tool would you choose to improve the application performance? (Select TWO.)

Answer options:

A.AWS VPN
B.AWS Global Accelerator
C.Direct Connect
D.API Gateway
E.CloudFront

Correct Answer – B, E
This web application has global users and needs low latency. Both CloudFront and Global Accelerator can speed up the distribution of contents over the AWS global network.
Option A is incorrect: AWS VPN links on-premise network to AWS network. However, no on-premise services are mentioned in this question.
Option B is CORRECT: AWS Global Accelerator works at the network layer and can direct traffic to optimal endpoints. For reference, check the link https://docs.aws.amazon.com/global-accelerator/latest/dg/what-is-global-accelerator.html
Option C is incorrect: Direct Connect links on-premise network to AWS network. However, no on-premise services are mentioned in this question.
Option D is incorrect: API Gateway is a regional service and cannot improve the application performance. API Gateway is suitable for serverless applications such as Lambda.
Option E is CORRECT: Because CloudFront delivers content through edge locations, and users are routed to the edge location with the lowest time delay.
