  description: >-
    Amazon EMR (Elastic MapReduce) provides a managed big data platform that
    simplifies running open-source frameworks such as Apache Spark and Hadoop
    to process and analyze vast amounts of data. This API enables you to
    create and manage clusters, add processing steps, configure auto-scaling,
    and monitor cluster health and performance.
