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.
