A company needs to have real-time access to image data while seamlessly maintaining a copy of the images in an offsite location for disaster recovery purposes. Which solution meets the requirement?
A.
Create an AWS Storage Gateway volume gateway configured as a stored volume. Mount it from clients using Internet Small Computer System Interface (iSCSI).
B.
Mount an Amazon EFS volume on a local server. Share this volume with employees who need access to the images.
C.
Store the images in Amazon S3, and use AWS Data Pipeline to allow for caching of S3 data on local workstations.
D.
Use Amazon S3 for file storage, and enable S3 Transfer Acceleration to maintain a cache for frequently used files to increase local performance.
AWS Storage Gateway is a hybrid cloud storage service that allows on-premises applications to seamlessly use cloud storage. It supports different gateway configurations, and in this case, a volume gateway configured as a stored volume is the most suitable option for the requirements.
A.
Stored volumes – If you need low-latency access to your entire dataset, first configure your on-premises gateway to store all your data locally. Then asynchronously back up point-in-time snapshots of this data to Amazon S3. This configuration provides durable and inexpensive offsite backups that you can recover to your local data center or Amazon Elastic Compute Cloud (Amazon EC2). For example, if you need replacement capacity for disaster recovery, you can recover the backups to Amazon EC2.
