Amazon SAA-C03 Exam - Topic 1 Question 68 Discussion

A company is designing an application on AWS that provides real-time dashboards. The dashboard data comes from on-premises databases that use a variety of schemas and formats. The company needs a solution to transfer and transform the data to AWS with minimal latency.Which solution will meet these requirements?
A) Integrate the dashboard with Amazon Managed Streaming for Apache Kafka (Amazon MSK) to transfer and transform the data from the on-premises databases to the dashboards.
B) Use Amazon Data Firehose to transfer the data to an Amazon S3 Bucket. Configure the dashboard application to import new data from the S3 bucket periodically.
C) Use AWS Database Migration Service (AWS DMS) Schema Conversion to consolidate the on-premises databases into a single AWS database. Use an AWS Lambda function that is scheduled by Amazon EventBridge to transfer data from the consolidated database to the dashboard application.
D) Use AWS DataSync to transfer data from the source databases to the dashboard application continuously. Configure the dashboard application to import data from DataSync.

A company is designing an application on AWS that provides real-time dashboards. The dashboard data comes from on-premises databases that use a variety of schemas and formats. The company needs a solution to transfer and transform the data to AWS with minimal latency.

Which solution will meet these requirements?

Show Suggested Answer Hide Answer
Suggested Answer: A

Amazon MSK is a fully managed, highly available Apache Kafka service for streaming data with low latency. Kafka Connect and stream processors enable ingest from heterogeneous sources and perform in-stream transformation before delivery to consumers (e.g., the dashboard service). This satisfies real-time updates from diverse schemas and formats. Kinesis alternatives could work, but among the given choices, MSK is the only streaming option designed for sub-second, continuous pipelines. Kinesis Data Firehose (B) buffers and batches data to S3 and is optimized for delivery to storage, not low-latency dashboards. AWS DMS schema conversion (C) focuses on database migration, not ongoing real-time, multi-format streaming for dashboards. AWS DataSync (D) is for file/object transfer, not database change streams. Hence, MSK best meets minimal-latency, transform-in-flight needs with managed operations.

AWS DataSync sounds familiar, but I can't recall if it supports continuous data transfer. I need to double-check that.

I practiced a similar question where Data Firehose was mentioned, but it seemed more suited for batch processing rather than real-time updates.

I think using Amazon MSK could work since it handles streaming data well, but I wonder if it might add complexity with the different schemas.

I'm leaning towards option B with Amazon Firehose. Transferring the data to S3 first and then having the dashboard app pull from there seems like a straightforward approach.
