A company runs a containerized microservices application on Amazon ECS using AWS Fargate across Availability Zones. The application requires shared, POSIX-compliant file storage that can handle highly unpredictable read/write spikes, support sub-millisecond (less than ) latencies for metadata operations, and dynamically scale throughput without manual intervention or administrative overhead.
Which two Amazon EFS configurations should a solutions architect select to meet these requirements? (Choose two.)
- Amazon EFS configured with General Purpose performance modeCevap
- Amazon EFS configured with Elastic throughput modeCevap
- CAmazon EFS configured with Max I/O performance mode
- DAmazon EFS configured with Provisioned throughput mode
- EAmazon EFS Archive storage class set as the primary target for active workloads
Cevap
The application requires Amazon EFS configured with General Purpose performance mode and Elastic throughput mode.
The correct configuration is Amazon EFS configured with General Purpose performance mode and Elastic throughput mode. General Purpose performance mode is optimized for latency-sensitive applications and provides sub-millisecond latencies for metadata operations. Elastic throughput mode automatically scales throughput capacity in response to workload activity, allowing the system to handle unpredictable spikes without manual provisioning or administrative overhead.
