A company is using an on-premises Microsoft SQL Server database that generates a nightly backup of 200 GB to a local drive. They wish to transfer these backups to more reliable cloud storage on Amazon S3. The company has already established a 10 Gbps AWS Direct Connect link between their on-premises data center and AWS. Which solution offers the most cost-effective approach to meet these requirements?
Explanation:
The correct answer is A. Deploying an AWS Storage Gateway file gateway within the VPC connected to the Direct Connect link and creating a new SMB file share is the most cost-effective solution for several reasons. File Gateway supports both SMB and NFS protocols, making it appropriate for this use case, and it directly integrates with Amazon S3, allowing the company to offload their nightly backups efficiently and cost-effectively to S3. Additionally, this solution leverages the existing Direct Connect connection for optimized network bandwidth, minimizing latency and potential data transfer charges. Option D, on the other hand, introduces complexity and potentially higher costs by involving volume gateway and extra steps in automating copies of data to S3.
