Zorluk: OrtaResilient and Highly Available Storage Infrastructure

A digital media agency is building a collaborative video editing platform on AWS. The editing application runs on a fleet of Amazon EC2 instances distributed across multiple Availability Zones in a single AWS Region. The instances require concurrent read and write access to a shared file workspace with sub-millisecond latencies. Additionally, the agency must archive completed video projects to minimize storage costs. In the event of a disaster, the archived files must be fully recoverable within a Recovery Time Objective (RTO) of 10 minutes. Which combination of storage solutions should a solutions architect recommend?

  1. A
    Use Amazon EBS gp3 volumes with Multi-Attach enabled across the EC2 instances for the active workspace. Store the archived projects in Amazon S3 Glacier Flexible Retrieval and use Standard retrievals during disaster recovery.
  2. Use Amazon EFS for the active collaborative workspace. Store the archived projects in Amazon S3 Glacier Flexible Retrieval and use Expedited retrievals during disaster recovery.Cevap
  3. C
    Use Amazon EFS for the active collaborative workspace. Store the archived projects in Amazon S3 Glacier Deep Archive and use Standard retrievals during disaster recovery.
  4. D
    Use Amazon EBS gp3 volumes with Multi-Attach enabled across the EC2 instances for the active workspace. Store the archived projects in Amazon S3 Standard-IA, deleting the archives after 15 days to save on storage fees.

Cevap

Use Amazon EFS for the active collaborative workspace. Store the archived projects in Amazon S3 Glacier Flexible Retrieval and use Expedited retrievals during disaster recovery.
Amazon EFS is a managed, shared file system that supports simultaneous read and write connections from multiple EC2 instances across multiple Availability Zones in a Region. It provides sub-millisecond latencies, which fits the active collaboration requirements. For the archival tier, Amazon S3 Glacier Flexible Retrieval using Expedited retrievals satisfies the 10-minute Recovery Time Objective (RTO) because it typically restores data within 1 to 5 minutes, while maintaining a lower storage cost relative to S3 Standard.

Adım Adım Çözüm

1
Analyze the active workspace storage requirements.
Identify that the storage must support concurrent read/write access from EC2 instances across multiple Availability Zones with sub-millisecond latency. Amazon EFS is a native POSIX-compliant shared file system that meets these requirements.
EBS volumes cannot be attached across multiple Availability Zones, and EBS Multi-Attach is limited to a single Availability Zone and only supported on io1/io2 volumes, not gp3.
2
Evaluate the archive storage retrieval options against the disaster recovery requirements.
The target RTO is 10 minutes. S3 Glacier Flexible Retrieval with Expedited retrievals recovers data in 1 to 5 minutes, which falls within the 10-minute threshold. Standard retrievals for Glacier Flexible Retrieval (3-5 hours) and Glacier Deep Archive (12 hours) are too slow.
Choosing the correct Glacier retrieval tier is critical to meeting strict RTOs while minimizing long-term archival costs.
3
Assess the cost optimization constraints.
Verify that deleting objects early in S3 Standard-IA is cost-prohibitive due to the 30-day minimum billing charge. EFS for hot data and S3 Glacier Flexible Retrieval with Expedited retrievals for cold data represents the most cost-effective and resilient architecture.
Avoiding S3 IA minimum duration penalties helps satisfy the requirement to minimize storage costs.

Anahtar Kavram

Selecting highly available and resilient shared storage (Amazon EFS) combined with fast-recovery archival solutions (S3 Glacier with Expedited retrievals) to satisfy concurrent access, Multi-AZ availability, and tight RTO limits.
