re6p, persistent memory optimized instance family

For answers to commonly asked questions about persistent memory optimized instances, see Instance FAQ.

Features

se1, memory optimized instance family

Features
  • Is an instance family in which all instances are I/O optimized.
  • Supports standard SSDs and ultra disks only.
  • Offers a CPU-to-memory ratio of 1:8.
  • Uses 2.5 GHz Intel® Xeon® E5-2682 v4 (Broadwell) processors for consistent computing performance.
  • Provides high network performance based on large computing capacity.
  • Suits the following scenarios:
    • High-performance and in-memory databases
    • Data analysis, data mining, and distributed memory caching
    • Hadoop clusters, Spark clusters, and other memory-intensive enterprise applications
