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 minutes and an RTO of 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?
- Configure Amazon S3 Cross-Region Replication (CRR) to automatically copy telemetry data to a destination bucket in the secondary region.Cevap
- Enable S3 Replication Time Control (RTC) on the replication rule configured for the telemetry data bucket.Cevap
- CReplicate telemetry objects to Amazon S3 Glacier Flexible Retrieval in the secondary region using standard retrievals during regional failover.
- DSet up AWS Volume Gateway in Cached mode to back up the data locally, configuring snapshots scheduled twice daily to the secondary region.
- EDeploy 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 -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 minutes, satisfying the -minute RPO requirement.
