Overview
An ECS is a basic computing unit that consists of vCPUs, memory, OS, and EVS disks.
After creating an ECS, you can use it like using your local computer or physical server and deploy applications in an efficient, reliable, and secure computing environment. ECSs support self-service creation, modification, and operation. To create an ECS, you need to specify its vCPUs, memory, OS, and login authentication. After the ECS is created, you can modify its specifications as needed.
There are a wide range of ECS types available to meet your compute and storage requirements. Each ECS type offers various flavors with different vCPU and memory configurations for you to choose from.
For details about ECS specifications, see ECS Types.
x86 CPU Architecture
General Computing ECSs
General computing ECSs provide basic vCPU performance and a balance of compute, memory, and networking resources. They use a CPU-unbound scheduling scheme, where vCPUs are randomly allocated to idle CPU hyper threads based on system loads. If traffic loads are light, the computing performance is high. However, if traffic loads are heavy, vCPUs of different ECSs compete for physical CPU resources, resulting in unstable computing performance.

General computing-plus aC7
Overview
aC7 ECSs use the latest-generation 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, insurance and finance.
