What are the MOST cost effective ways to increase upload speeds into the S3 bucket?
(Choose two.)
Create multiple AWS Direct Connect connections between AWS and branch offices in Europe and Australia for file uploads into the destination S3 bucket.
Create multiple AWS Site-to-Site VPN connections between AWS and branch offices in Europe and Australia for file uploads into the destination S3 bucket.
Use Amazon S3 Transfer Acceleration for file uploads into the destination S3 bucket.
Use AWS Global Accelerator for file uploads into the destination S3 bucket from the branch offices in Europe and Australia.
Use multipart uploads for file uploads into the destination S3 bucket from the branch offices in Europe and Australia.
Explanations:
AWS Direct Connect provides dedicated network connections but can be expensive, especially across multiple geographies. It is not the most cost-effective solution for increasing upload speeds for this use case.
AWS Site-to-Site VPN provides secure connections but may introduce latency and performance limitations, particularly over long distances like from Europe and Australia to the US. This is not the most cost-effective option.
Amazon S3 Transfer Acceleration improves upload speeds to S3 by using a globally distributed edge network to route data to the closest AWS region. It is cost-effective for large file uploads over long distances.
AWS Global Accelerator is designed to improve global application performance but is more suited for optimizing latency and availability for applications, not specifically for file uploads to S3.
Multipart uploads allow large files to be uploaded in parts, which can speed up the process by uploading in parallel. This is an efficient and cost-effective way to upload large files to S3.
