Amazon EMR
Big data processing service
Amazon EMR (Elastic MapReduce) is a managed cluster platform that simplifies running big data frameworks on AWS. It processes and analyzes vast amounts of data using open-source tools like Apache Hadoop, Apache Spark, Apache Hive, and Presto. EMR handles provisioning, configuration, and tuning of the underlying infrastructure. Users focus on analyzing data rather than managing the environment. EMR clusters consist of EC2 instances organized into node types: 1. Primary Node: Manages the cluster, coordinates data distribution 2. Core Nodes: Run tasks and store data in HDFS 3. Task Nodes: Optional compute-only resources for additional processing power EMR offers several key benefits: • Cost efficiency with pay-as-you-go pricing and Spot Instance support • Scalability to adjust resources as processing needs change • Security through IAM, VPC integration, and encryption options • Integration with other AWS services (S3, DynamoDB, Redshift) • Multiple deployment options including on-demand, persistent clusters, or EMR Serverless Typical use cases include: • Log analysis and business intelligence • Machine learning and scientific simulation • ETL (Extract, Transform, Load) operations • Financial analysis and risk modeling • Genomics processing When designing EMR solutions, consider: • Storing data in S3 instead of HDFS for persistence and cost benefits • Using instance fleets or Spot Instances for optimal cost management • Rightsizing clusters based on workload requirements • Implementing automated scaling rules • Creating EMR steps for workflow orchestration EMR Serverless provides an additional deployment option that eliminates the need to configure, optimize, secure, or operate clusters for transient workloads.
