General Computing-plus aC8

Overview

aC8 ECSs use the next-generation scalable processors with turbo frequency up to 3.7 GHz and 4,800 MHz DDR5 memory. With the next-generation QingTian architecture, aC8 ECSs provide more robust and stable computing and network performance as well as all-scenario security and trustworthiness capabilities.

Notes

When you select a Windows Server image for an aC8 ECS with 192 vCPUs, the OS version must be one of the following:

  • Windows Server 2019 (October 2022, OS build:17763.3532 or later)
  • Windows Server 2022 (July 2022, OS build: 20348.859 or later)

Scenarios

Medium- and heavy-load enterprise applications with strict requirements on computing and network performance, such as web applications, e-commerce platforms, short video platforms, online games, and insurance and finance.
