Question 29
A data analytics company wants to seamlessly integrate its on-premises data center with AWS cloud-based IT systems which would be critical to manage as well as scale-up the complex planning and execution of every stage of its analytics workflows. As part of a pilot program, the company wants to integrate data files from its on-premises servers into AWS via an NFS interface.
Which of the following AWS service is the MOST efficient solution for the given use-case?
-
A
AWS Site-to-Site VPN
-
B
AWS Storage Gateway - Volume Gateway
-
C
AWS Storage Gateway - File Gateway
-
D
AWS Storage Gateway - Tape Gateway
Reveal correct answer
Correct answer: C
Explanation
Correct option:
AWS Storage Gateway - File Gateway
AWS Storage Gateway is a hybrid cloud storage service that gives you on-premises access to virtually unlimited cloud storage. The service provides three different types of gateways – Tape Gateway, File Gateway, and Volume Gateway – that seamlessly connect on-premises applications to cloud storage, caching data locally for low-latency access.
AWS Storage Gateway's file interface, or file gateway, offers you a seamless way to connect to the cloud in order to store application data files and backup images as durable objects on Amazon S3 cloud storage. File gateway offers SMB or NFS-based access to data in Amazon S3 with local caching. As the company wants to integrate data files from its analytical instruments into AWS via an NFS interface, therefore AWS Storage Gateway - File Gateway is the correct answer.
File Gateway Overview:
Incorrect options:
AWS Storage Gateway - Volume Gateway - You can configure the AWS Storage Gateway service as a Volume Gateway to present cloud-based iSCSI block storage volumes to your on-premises applications. Volume Gateway does not support NFS interface, so this option is not correct.
AWS Storage Gateway - Tape Gateway - AWS Storage Gateway - Tape Gateway allows moving tape backups to the cloud. Tape Gateway does not support NFS interface, so this option is not correct.
AWS Site-to-Site VPN - AWS Site-to-Site VPN enables you to securely connect your on-premises network or branch office site to your Amazon Virtual Private Cloud (Amazon VPC). You can securely extend your data center or branch office network to the cloud with an AWS Site-to-Site VPN (Site-to-Site VPN) connection. It uses internet protocol security (IPSec) communications to create encrypted VPN tunnels between two locations. You cannot use AWS Site-to-Site VPN to integrate data files via the NFS interface, so this option is not correct.
