Amazon EMR
Amazon EMR (Elastic MapReduce) is a managed big data platform on AWS that simplifies running distributed data processing frameworks like Apache Spark, Hadoop, and Presto. It handles cluster provisioning, configuration, and scaling, allowing developers to focus on data analysis and processing tasks. EMR supports various applications for data processing, machine learning, and analytics across large datasets stored in AWS services like S3.
Developers should use Amazon EMR when they need to process large-scale data efficiently in the cloud, such as for log analysis, data transformation, or machine learning workloads. It is ideal for scenarios requiring scalable, cost-effective big data processing without the overhead of managing infrastructure, especially when integrated with other AWS services for a seamless data pipeline.
