AWS Certified Solutions Architect – ProfessionalContinuously Improve Existing SolutionsEasy
A global online learning platform serves video content to millions of users worldwide. The platform currently hosts all video assets in a single Amazon S3 bucket, and users directly access these files. During peak hours, users in distant geographical regions experience high latency and buffering, leading to a poor user experience. The company wants to improve content delivery performance, reduce latency for global users, and offload traffic from the S3 origin while minimizing infrastructure management. Which AWS service should the Solutions Architect recommend to address these issues?
- AAWS Global Accelerator
- BAmazon CloudFront
- CAmazon S3 Transfer Acceleration
- DAWS Direct Connect
Show answer & explanationAnswer & explanation
Correct answer: B. Amazon CloudFront
Amazon CloudFront is a global content delivery network (CDN) service that securely delivers data, videos, applications, and APIs to customers globally with low latency and high transfer speeds. It caches content at edge locations closer to users, reducing load on the S3 origin.
Why the other options are wrong
- A. AWS Global Accelerator improves availability and performance for applications by directing traffic to optimal endpoints over the AWS global network. While it can improve performance, CloudFront is specifically designed for caching and delivering web content, including video, which is the primary use case here.
- C. S3 Transfer Acceleration speeds up uploads to S3, not content delivery to end-users from S3.
- D. AWS Direct Connect establishes a dedicated network connection from an on-premises data center to AWS, which is irrelevant for improving global user access to S3-hosted content.
