Which AWS service is a serverless ETL service that runs Spark jobs without managing clusters and integrates directly with Amazon S3?
💡 Model Answer
AWS Glue is the serverless ETL service that runs Apache Spark jobs without requiring you to provision or manage clusters. It automatically scales the underlying compute resources based on the size of the data and the complexity of the job. Glue integrates natively with Amazon S3, using it as both the source and destination for data. The service also provides a Glue Data Catalog that stores metadata about data assets, enabling other services like Athena and Redshift Spectrum to query the data directly. Glue’s job scheduling, monitoring, and logging are built into the console, making it a convenient choice for data engineers who want to focus on transformation logic rather than infrastructure.
