Memory-optimized ECSs

Overview

  • M9 ECSs use the sixth-generation Intel® Xeon® Scalable processors and KVM virtualization to provide enhanced compute, network, and security performance to fulfill the high-performance and large-memory requirements.
  • M7n ECSs use the third-generation Intel® Xeon® Scalable processors to provide enhanced compute, security, and stability. Each M7n ECS can have a maximum number of 96 vCPUs and a memory speed of 3,200 MHz, and provide a secure and trusted cloud environment for memory-intensive compute applications.
  • M4 ECSs use the second-generation Intel® Xeon® Scalable processors with technologies optimized to offer powerful and stable compute performance. Using 25GE high-speed intelligent NICs, M4 ECSs provide a maximum memory size of 512 GiB based on DDR4 for memory-intensive applications with high requirements on network bandwidth and PPS.
  • M3 ECSs are developed based on the KVM virtualization platform and designed for processing large-scale data sets in memory. They use Intel® Xeon® Scalable processors, network acceleration engines, and DPDK rapid packet processing to provide higher network performance and up to 512 GiB of DDR4 memory for memory-intensive compute applications.

Scenarios

  • High-performance relational (MySQL) and NoSQL (MongoDB and Cassandra) databases
  • Distributed web scale cache stores that provide in-memory caching of key-value type data (Memcached and Redis)
  • Applications processing big unstructured data in real time (financial services, Hadoop/Spark clusters)
  • High-performance computing (HPC) and electronic design automation (EDA)
