What should a solutions architect do to reduce costs?
Configure Amazon CloudFront with the existing website as the origin.
Move the website to Amazon EC2 with Amazon Elastic Block Store (Amazon EBS) volumes for storage.
Use AWS Global Accelerator and specify the existing website as the endpoint.
Rearchitect the website to run on a combination of Amazon API Gateway and AWS Lambda.
Explanations:
Using Amazon CloudFront, a content delivery network (CDN), can cache content closer to users, reducing the outbound traffic costs from S3.
Moving to EC2 with EBS increases costs due to instance and storage charges, without significantly reducing outbound data transfer costs.
AWS Global Accelerator is primarily for improving availability and performance, not for reducing data transfer costs from S3.
Rearchitecting to API Gateway and Lambda could introduce additional costs and complexity without a clear reduction in outbound traffic expenses.
If memory serves me right, the answer is:
Configure Amazon CloudFront with the existing website as the origin.
