General Computing-plus ECSs

Overview

General computing-plus ECSs use dedicated vCPUs to deliver powerful performance. In addition, the ECSs use the latest-generation network acceleration engines and DPDK to provide high network performance.

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

Available now: C7, C7n, C7t, C7h, aC7, X1e, C6s, C6h, C6, C3ne, and C3

aC7

Overview

aC7 ECSs use scalable processors to provide enhanced computing, security, and stability. An aC7 ECS can have a maximum number of 232 vCPUs and a memory speed of 3,200 MHz.

Notes

aC7 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 DPDK to mask the differences among ECS kernel protocol stacks to get the actual network performance.

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.
