The logical architecture of EMR is as shown below:

An EMR cluster consists mainly of three parts: open-source components, Tencent Cloud infrastructure, and cluster management.

  • Open-source components
    • EMR integrates dozens of cutting-edge open-source big data components from the Apache community, such as Hadoop, Hive, Spark, HBase, Presto, Flink, Alluxio, and Iceberg. For more information, see Product Releases and Component Versions.
    • EMR is optimized based on open-source components such as Spark, Iceberg, and Alluxio. It has capability and feature enhancements, including Spark materialized view (TianQiong Edition) and Alluxio transparent URI.
  • Tencent Cloud infrastructure
    • EMR can be deployed based on multiple types of underlying computing resources, including CVM and CPM. It supports containerized deployment.
    • Data can be stored in a local disk, cloud disk, COS bucket, or CHDFS instance.
    • VPCs, network ACLs, and security groups provide EMR with a securely isolated network environment.
  • Cluster management
    • EMR supports smart cloud deployment management, including fast creation, flexible scaling, and auto scaling.
    • EMR offers a great variety of convenient Ops tools, such as service configuration management, batch node management, and visual service Ops.
    • EMR provides complete cluster monitoring and diagnosis capabilities ranging from multidimensional metric monitoring, event, and inspection to alarming and log search.
