Which solution will meet these requirements with the LEAST implementation effort?
Configure an Amazon CloudFront distribution for the S3 bucket to improve the download performance. Enable S3 Transfer Acceleration to improve the upload performance.
Configure Amazon EC2 instances of the right sizes in multiple AWS Regions. Migrate the application to the EC2 instances. Use an Application Load Balancer to distribute the website traffic equally among the EC2 instances. Configure AWS Global Accelerator to address global demand with low latency.
Configure an Amazon CloudFront distribution that uses the S3 bucket as an origin to improve the download performance. Configure the application to use CloudFront to upload images to improve the upload performance. Create S3 buckets in multiple AWS Regions. Configure replication rules for the buckets to replicate users’ data based on the users’ location. Redirect downloads to the S3 bucket that is closest to each user’s location.
Configure AWS Global Accelerator for the S3 bucket to improve network performance. Create an endpoint for the application to use Global Accelerator instead of the S3 bucket.
Explanations:
Configuring an Amazon CloudFront distribution for the S3 bucket will cache the images closer to users, significantly improving download performance due to reduced latency. Enabling S3 Transfer Acceleration will utilize Amazon’s edge locations to speed up uploads from users to the S3 bucket, effectively addressing both upload and download latency issues with minimal implementation effort.
While migrating to Amazon EC2 instances with an Application Load Balancer can distribute traffic and potentially improve performance, this option involves significantly more implementation effort, including configuring, managing, and scaling EC2 instances across multiple regions. This does not address the immediate latency issues as efficiently as leveraging existing AWS services like CloudFront.
Although using CloudFront for downloads and creating multiple S3 buckets for geographic distribution addresses latency, it introduces higher implementation complexity with the need to manage multiple S3 buckets and replication rules. The requirement for a more straightforward solution with less implementation effort makes this option less ideal.
AWS Global Accelerator is designed to improve network performance by routing traffic to optimal endpoints. However, it does not directly support S3 as an endpoint, as S3 is not a TCP endpoint but rather an object storage service. Thus, this option would not be viable for enhancing performance in the context of this website.
I would say the answer is:
Configure an Amazon CloudFront distribution for the S3 bucket to improve the download performance. Enable S3 Transfer Acceleration to improve the upload performance.
