This topic describes specific memory instance type families, and lists the specific instance types within each of the instance type families. Specifically, the instance type families to be described are: memory instance type family r5, memory-optimized instance type families with enhanced performance re4 and re4e, memory optimized instance type family with enhanced network performance se1ne, and memory-optimized instance type family se1.

r5, memory instance type family

Features

  • I/O-optimized
  • Supports SSD Cloud Disks and Ultra Disks
  • Ultra high packet forwarding rate
  • Equipped with 2.5 GHz Intel Xeon Platinum 8163 (Skylake) processors
  • Supports strong network performance through sufficient computing capacity
  • Suitable for the following scenarios:
    • Scenarios where a large volume of packets are received and transmitted, such as the re-transmission of telecommunication information
    • High-performance databases and high memory databases
    • Data analysis and mining, and distributed memory cache
    • Hadoop, Spark, and other enterprise-level applications with large memory requirements
