Memory-optimized ECSs

Overview

Memory-optimized ECSs have a large memory size and provide high memory performance. They are designed for memory-intensive applications that process a large amount of data, such as precision marketing, e-commerce, and IoV big data analysis.

Hyper-threading is enabled for this type of ECSs by default. Each vCPU is a thread of a CPU core.

Available now: M7, aM7, M7n, M6, M3ne, M3, and M2

Memory-optimized aM7

Overview

aM7 ECSs use scalable processors to provide enhanced computing, security, and stability. An aM7 ECS can have a maximum number of 232 vCPUs and a memory speed of 3,200 MHz. They are suitable for memory-intensive computing applications.

Notes

aM7 ECSs offer an intranet bandwidth of up to 100 Gbit/s and network forwarding capacity of up to 20 million PPS. When the bandwidth is higher than 50 Gbit/s and the network forwarding packets exceed 10 million PPS, you can use Data Plane Development Kit (DPDK) to mask the differences among ECS kernel protocol stacks to get the actual network performance.

Scenarios

  • Massively parallel processing (MPP) of data warehouse
  • MapReduce and Hadoop distributed computing
  • Distributed file systems
  • Network file system, log, or data processing applications
