DEA-C01 Question 325

Single answer

You are a Data Engineer designing a real-time data processing pipeline for an e-commerce platform. The pipeline needs to handle millions of transactions per day with low latency. The platform requires you to process incoming data from a Kinesis Data Stream and store the results in Amazon S3 for further analysis. Which AWS service would you choose to process the data efficiently and why?

  1. A

    Amazon Kinesis Data Firehose

  2. B

    AWS Glue

  3. C

    AWS Lambda

  4. D

    Amazon Kinesis Data Analytics

Show answer and explanation

Correct answer: D

Explanation

Amazon Kinesis Data Analytics is the ideal choice for real-time processing of streaming data from Kinesis Data Streams. It is purpose-built for analyzing and transforming high-throughput streaming data with low latency. Unlike AWS Glue (batch ETL), Lambda (event-driven but limited for large-scale analytics), or Firehose (data delivery), Kinesis Data Analytics provides the tools needed for efficient real-time stream processing using SQL or Apache Flink.

  • A. Incorrect.

    Amazon Kinesis Data Firehose is primarily used for data delivery and transformation, not for real-time stream processing. It is not suitable for complex data processing tasks that require analytics or aggregations.

  • B. Incorrect.

    AWS Glue is a serverless data integration service typically used for ETL (Extract, Transform, Load) jobs in batch processing scenarios, not for real-time data stream processing.

  • C. Incorrect.

    AWS Lambda can process real-time events, but it is not ideal for large-scale analytics or aggregations on streams of data. It has limitations in terms of concurrency and execution time, which can be challenging for high-throughput, low-latency scenarios.

  • D. Correct.

    Amazon Kinesis Data Analytics is specifically designed for real-time analytics and processing on streaming data. It supports SQL queries and integrates seamlessly with Amazon Kinesis Data Streams for processing high-throughput data streams efficiently.
