Question
A company needs to migrate its critical SAP workloads from an on-premises data center to AWS. The company has a few source production databases that are 10 TB or more in size. The company wants to minimize the downtime for this migration. As part of the proof of concept, the company used a low-speed, high-latency connection between its data center and AWS. During the actual migration, the company wants to maintain a consistent connection that delivers high bandwidth and low latency. The company also wants to add a layer of connectivity resiliency. The backup connectivity does not need to be as fast as the primary connectivity. An SAP solutions architect needs to determine the optimal network configuration for data transfer. The solution must transfer the data with minimum latency. Which configuration will meet these requirements?
Options
- ASet up one AWS Direct Connect connection for connectivity between the on-premises data center
- BSet up an AWS Direct Connect gateway with multiple Direct Connect connections that use a link
- CSet up Amazon Elastic File System (Amazon EFS) file system storage between the on-premises
- DSet up two redundant AWS Site-to-Site VPN connections for connectivity between the on-premises

Explanation
Option A - a single AWS Direct Connect connection as the primary link combined with an AWS Site-to-Site VPN as backup - meets all stated requirements. AWS Direct Connect provides a dedicated, private network connection with consistent high bandwidth and low latency, which is essential for transferring large (10 TB+) SAP production databases with minimum latency. The VPN serves as the backup connectivity layer; it uses the public internet so it is less performant than Direct Connect, which aligns with the requirement that backup connectivity does not need to match primary speed. Multiple Direct Connect connections with a LAG (B) adds cost and complexity beyond what is needed. Amazon EFS (C) is a file storage service, not a network connectivity solution. Two VPN connections (D) do not provide the dedicated, low-latency, high-bandwidth path that large SAP database migrations require.
