Zorluk: OrtaResilient and Highly Available Storage Infrastructure

A global agricultural logistics company is migrating its telemetry archiving system to AWS. The system must store critical supply chain data with an RPO of 1515 minutes and an RTO of 3030 minutes. The architecture must ensure the data is resilient to regional disasters and remains immediately readable from a secondary destination region for localized reporting. Which two configurations should the solutions architect combine to meet these resilience and recovery requirements?

  1. Configure Amazon S3 Cross-Region Replication (CRR) to automatically copy telemetry data to a destination bucket in the secondary region.Cevap
  2. Enable S3 Replication Time Control (RTC) on the replication rule configured for the telemetry data bucket.Cevap
  3. C
    Replicate telemetry objects to Amazon S3 Glacier Flexible Retrieval in the secondary region using standard retrievals during regional failover.
  4. D
    Set up AWS Volume Gateway in Cached mode to back up the data locally, configuring snapshots scheduled twice daily to the secondary region.
  5. E
    Deploy Amazon RDS Multi-AZ instances with read replicas in the secondary region to store the raw telemetry objects.

Cevap

To meet the requirements, the solutions architect should configure Amazon S3 Cross-Region Replication (CRR) to copy telemetry data to the destination bucket and enable S3 Replication Time Control (RTC) to ensure replication is completed within the 1515-minute RPO.
Configuring Amazon S3 Cross-Region Replication (CRR) copies objects to a secondary region automatically, keeping the data immediately readable. Enabling S3 Replication Time Control (RTC) enforces replication within 1515 minutes, satisfying the 1515-minute RPO requirement.

Adım Adım Çözüm

1
Select the appropriate storage service for storing raw telemetry objects across regions.
Amazon S3 with Cross-Region Replication (CRR) is selected, ensuring durability and cross-region disaster recovery.
This establishes a replicated object repository that supports immediate, active read access in the destination region.
2
Configure Replication Time Control (RTC) on the S3 replication rule.
RTC guarantees that 99.99%99.99\% of objects replicate within 1515 minutes.
This configuration directly aligns with the strict RPO constraint of 1515 minutes.

Anahtar Kavram

Amazon S3 Cross-Region Replication with Replication Time Control (RTC) to guarantee strict RPO/RTO constraints.
