A company is migrating its product development teams from an on-premises data center to a hybrid environment.The new environment will add four AWS Regions and will give the developers the ability to use the Region that is geographically closest to them.All the development teams use a shared set of Linux applications.The on-premises data center stores the applications on a NetApp ONTAP storage device.The storage volume is mounted read-only on the development on-premises VMs.The company updates the applications on the shared volume once a week.A DevOps engineer needs to replicate the data to all the new Regions.The DevOps engineer must ensure that the data is always up to date with deduplication.The data also must not be dependent on the availability of the on-premises storage device.

Which solution will meet these requirements?

Create an Amazon S3 File Gateway in the on-premises data center. Create S3 buckets in each Region. Set up a cron job to copy the data from the storage device to the S3 File Gateway. Set up S3 Cross-Region Replication (CRR) to the S3 buckets in each Region.

Create an Amazon FSx File Gateway in one Region. Create file servers in Amazon FSx for Windows File Server in each Region. Set up a cron job to copy the data from the storage device to the FSx File Gateway.

Create Multi-AZ Amazon FSx for NetApp ONTAP instances and volumes in each Region. Configure a scheduled SnapMirror relationship between the on-premises storage device and the FSx for ONTAP instances.

Create an Amazon Elastic File System (Amazon EFS) file system in each Region. Deploy an AWS DataSync agent in the on-premises data center. Configure a schedule for DataSync to copy the data to Amazon EFS daily.

Explanations:

While using an S3 File Gateway and S3 Cross-Region Replication (CRR) allows for data storage in multiple Regions, it does not guarantee real-time updates. The cron job may lead to delays in replication and potential outdated data across Regions.

Amazon FSx for Windows File Server is not optimized for Linux applications and does not provide deduplication. Additionally, the requirement of ensuring data is not dependent on the on-premises storage device is not met, as the solution still relies on copying data from it.

Multi-AZ Amazon FSx for NetApp ONTAP allows for high availability and data redundancy. Configuring SnapMirror relationships ensures that data is synchronized and updated in real-time across Regions. This option meets the requirement of maintaining up-to-date data without relying on on-premises storage.

Although Amazon EFS and AWS DataSync provide a robust solution for transferring data, the daily schedule may not ensure real-time data updates. Moreover, EFS is not designed for a multi-Region scenario without additional complexities, which does not satisfy the requirement for immediate availability across all Regions.
