Question

A financial services company runs a hybrid architecture and currently connects its on-premises data center to AWS using a single Site-to-Site VPN over the public internet. Over the past year, data transfer to AWS has grown to a sustained 2 TB per day, and the company reports that the per-GB data transfer charges plus inconsistent throughput are causing both budget overruns and application latency complaints. Management wants the most cost-effective long-term solution that reduces per-GB data transfer costs and provides predictable bandwidth. What should the solutions architect recommend?

Accepted Answer

Provision an AWS Direct Connect dedicated connection between the data center and AWS to obtain lower, consistent data transfer rates and predictable bandwidth.

Answer

Add multiple additional Site-to-Site VPN tunnels and use ECMP to increase aggregate throughput over the internet.

Answer

Route all traffic through a NAT gateway in the VPC to reduce data transfer charges from on-premises.

Answer

Enable S3 Transfer Acceleration so the on-premises uploads use the CloudFront edge network at a lower cost.
