Question
A company is deploying a new web-based application and needs a storage solution for the Linux application servers. The company wants to create a single location for updates to application data for all instances. The active dataset will be up to 100 GB in size. A solutions architect has determined that peak operations will occur for 3 hours daily and will require a total of 225 MiBps of read throughput. The solutions architect must design a Multi-AZ solution that makes a copy of the data available in another AWS Region for disaster recovery (DR). The DR copy has an RPO of less than 1 hour. Which solution will meet these requirements?
Options
- ADeploy a new Amazon Elastic File System (Amazon EFS) Multi-AZ file system. Configure the file
- BDeploy a new Amazon FSx for Lustre file system. Configure Bursting Throughput mode for the file
- CDeploy a General Purpose SSD (gp3) Amazon Elastic Block Store (Amazon EBS) volume with
- DDeploy an Amazon FSx for OpenZFS file system in both the production Region and the DR

Why each option
To provide a shared, high-throughput file system for Linux servers with burstable performance and cross-region disaster recovery, an Amazon FSx for Lustre file system with Bursting Throughput mode is recommended. Data can be linked to Amazon S3, enabling cross-region replication for a low Recovery Point Objective (RPO).
Amazon EFS would require expensive Provisioned Throughput to meet the 225 MiBps requirement on a 100 GB file system, as its burst throughput based on size is insufficient.
Amazon FSx for Lustre is a high-performance file system optimized for Linux workloads, and its Bursting Throughput mode can provide the required 225 MiBps for a 100 GB dataset cost-effectively for short durations. For disaster recovery, the file system can be configured to integrate with Amazon S3, where data is persistently stored and can be replicated to another AWS Region via S3 Cross-Region Replication to achieve an RPO of less than 1 hour.
Amazon EBS is block storage attached to a single EC2 instance, not a shared file system that can be accessed by multiple application instances simultaneously.
Amazon FSx for OpenZFS does not offer a specific Bursting Throughput mode that aligns with the cost-effective burst requirement for a 100 GB dataset as effectively as FSx for Lustre.
