What can a solutions architect do to improve the performance of these uploads while ensuring only authenticated users are allowed to post content?
Set up an Amazon API Gateway with an edge-optimized API endpoint that has a resource as an S3 service proxy. Configure the PUT method for this resource to expose the S3 PutObject operation. Secure the API Gateway using a COGNITO_USER_POOLS authorizer. Have the browser interface use API Gateway instead of the presigned URL to upload objects.
Set up an Amazon API Gateway with a regional API endpoint that has a resource as an S3 service proxy. Configure the PUT method for this resource to expose the S3 PutObject operation. Secure the API Gateway using an AWS Lambda authorizer. Have the browser interface use API Gateway instead of the presigned URL to upload objects.
Enable an S3 Transfer Acceleration endpoint on the S3 bucket. Use the endpoint when generating the presigned URL. Have the browser interface upload the objects to this URL using the S3 multipart upload API.
Configure an Amazon CloudFront distribution for the destination S3 bucket. Enable PUT and POST methods for the CloudFront cache behavior. Update the CloudFront origin to use an origin access identity (OAI). Give the OAI user 3: PutObject permissions in the bucket policy. Have the browser interface upload objects using the CloudFront distribution.
Explanations:
This option uses API Gateway to upload files, which may introduce latency compared to direct S3 uploads, especially for larger files. Additionally, while it secures uploads via Cognito, it does not leverage S3’s capabilities for efficient large file transfers.
Similar to Option A, this approach uses API Gateway as a proxy to S3, which can lead to slower upload times due to the overhead of API Gateway. It also uses a Lambda authorizer, which does not improve performance for larger uploads.
Enabling S3 Transfer Acceleration optimizes uploads by utilizing Amazon’s global network of edge locations, providing faster upload speeds, especially for large files. This option also maintains user authentication through presigned URLs, ensuring secure uploads.
While CloudFront can help with caching and delivering content, it is not optimal for direct uploads to S3. Enabling PUT and POST methods does not inherently improve upload performance for large files, and it complicates the upload flow compared to using S3 directly with Transfer Acceleration.
I strategize that the answer is:
Enable an S3 Transfer Acceleration endpoint on the S3 bucket. Use the endpoint when generating the presigned URL. Have the browser interface upload the objects to this URL using the S3 multipart upload API.
