A city’s open-data program needs distributed Apache Spark jobs to transform large civic datasets before publishing. Which AWS service is the appropriate managed big-data processing cluster choice?
Select an answer to reveal the explanation.
Short Explanation
Spark wants a real big-data cluster, not a website host or a desktop farm. EMR is the AWS managed path for distributed Spark jobs that reshape city open data at scale. Amplify hosts apps, WorkSpaces are desktops, and Transit Gateway moves packets—it doesn’t run Spark stages.
Full Explanation
Amazon EMR provides managed Hadoop/Spark clusters for large-scale data processing and transformation. For municipal open-data ETL using Spark, EMR is the Task 3.2 high-performing compute selection. Amplify, WorkSpaces, and Transit Gateway address hosting, desktops, and networking respectively, not distributed Spark execution.
