What should a solutions architect do to meet these requirements?
Setup an AWS DataSync agent to replicate the prefixed data from the source S3 bucket to the destination S3 bucket. Select to use all available bandwidth on the task, and monitor the task to ensure that itis in the TRANSFERRING status. Create an Amazon EventBridge rule to initiate an alert if this status changes.
In the second account, create another S3 bucket to receive data from the radar station with the most accurate data. Set up a new replication rule for this new S3 bucket to separate the replication from the other radar stations. Monitor the maximum replication time to the destination. Create an Amazon EventBridge rule to initiate an alert when the time exceeds the desired threshold.
Enable Amazon S3 Transfer Acceleration on the source S3 bucket, and configure the radar station with the most accurate data to use the new endpoint. Monitor the S3 destination bucket’s TotalRequestLatency metric. Create an Amazon EventBridge rule to initiate an alert if this status changes.
Create a new S3 replication rule on the source S3 bucket that filters for the keys that use the prefix of the radar station with the most accurate data. Enable S3 Replication Time Control (S3 RTC). Monitor the maximum replication time to the destination. Create an Amazon EventBridge rule to initiate an alert when the time exceeds the desired threshold.
Explanations:
AWS DataSync is designed for data transfer between on-premises storage and AWS or between AWS services, but it is not necessary here since S3 replication can handle this natively. Also, monitoring the TRANSFERRING status does not ensure completion within 30 minutes, as the status may not reflect the actual replication time effectively.
Creating a new S3 bucket for the radar station with the most accurate data adds unnecessary complexity and does not utilize S3 replication effectively. The requirement is for monitoring the existing replication process, and creating a separate bucket could lead to inconsistency and increased management overhead.
While S3 Transfer Acceleration can reduce latency for uploads, it does not inherently solve the requirement of monitoring replication completion within 30 minutes. Additionally, monitoring the TotalRequestLatency metric of the destination bucket does not directly reflect the replication time, and thus would not guarantee compliance with the 30-minute requirement.
This option correctly implements a targeted S3 replication rule for the specific radar station’s data. Enabling S3 Replication Time Control (RTC) allows for monitoring of the replication time, ensuring that it meets the 30-minute compliance requirement. The use of EventBridge for alerting if the replication time exceeds the threshold is a robust solution.
I structure that the answer is:
Create a new S3 replication rule on the source S3 bucket that filters for the keys that use the prefix of the radar station with the most accurate data. Enable S3 Replication Time Control (S3 RTC). Monitor the maximum replication time to the destination. Create an Amazon EventBridge rule to initiate an alert when the time exceeds the desired threshold.
