Zorluk: OrtaHigh-Performing and Scalable Storage Solutions

A financial services firm is deploying a containerized risk analysis platform on Amazon Elastic Kubernetes Service (Amazon EKS) across two Availability Zones. The platform's pods require concurrent, shared read and write access to a persistent storage volume that supports standard POSIX file systems, permissions, and locking. The storage must handle up to 15,000 IOPS15,000\text{ IOPS} during peak processing times, and must scale throughput and capacity automatically without manual provisioning or downtime.

Which of the following configurations should a solutions architect recommend? (Select TWO.)

  1. Create an Amazon EFS file system configured with Elastic throughput mode and mount it using the Amazon EFS CSI driver.Cevap
  2. Deploy an Amazon FSx for NetApp ONTAP Multi-AZ file system and mount the volumes using the NFS protocol.Cevap
  3. C
    Provision an Amazon EBS gp3 volume, enable Multi-Attach, and mount it to the worker nodes using the Amazon EBS CSI driver.
  4. D
    Provision an Amazon EBS io2 volume, enable Multi-Attach, and mount it to the worker nodes across both Availability Zones.
  5. E
    Create an Amazon S3 bucket and mount it as a local file system using the Amazon S3 CSI driver.

Cevap

The correct configurations are to use an Amazon EFS file system configured with Elastic throughput mode mounted via the Amazon EFS CSI driver, and to deploy an Amazon FSx for NetApp ONTAP Multi-AZ file system mounted via NFS.
The correct configurations are the option to use Amazon EFS with Elastic throughput mode and the option to use Amazon FSx for NetApp ONTAP Multi-AZ file system. Amazon EFS is built to scale automatically and supports concurrent access from multiple pods across different Availability Zones with full POSIX compatibility. Amazon FSx for NetApp ONTAP Multi-AZ provides a fully managed shared file system that supports POSIX compliance, NFS access, and scales performance and capacity seamlessly to meet the 15,000 IOPS15,000\text{ IOPS} demand.

Adım Adım Çözüm

1
Analyze the workload requirements: multi-AZ containerized platform (EKS), concurrent read/write access (shared storage), POSIX compliance (file system, permissions, locking), high IOPS, and automated scaling.
Identified that standard single-instance block storage (EBS gp3/io2 without multi-AZ support) and object storage (S3) are unsuitable.
This narrows down the selection to shared file storage solutions that natively support POSIX and multi-AZ deployments.
2
Evaluate Amazon EFS with Elastic throughput mode.
Amazon EFS satisfies the POSIX file system and concurrent access requirements across multiple Availability Zones, and Elastic throughput mode ensures automatic performance scaling.
Elastic throughput mode matches the requirement of scaling throughput automatically without manual provisioning.
3
Evaluate Amazon FSx for NetApp ONTAP Multi-AZ deployment.
FSx for NetApp ONTAP is fully POSIX-compliant, supports NFS, can be deployed across multiple Availability Zones, and offers high-performance throughput scaling.
It matches the high performance, multi-AZ access, and POSIX compliance requirements.
