Node Specifications

This section describes the node specifications supported by CCE and typical node features.

Node Type

Description

Specifications

ECS (VM)

ECS running on a KVM or QingTian hypervisor. Multiple flavors are offered to meet your compute and storage needs for various applications.

x86:

Arm (Kunpeng):

Heterogeneous:

ECS (PM)

ECS running on a QingTian-backed bare-metal hypervisor. PM resources and VM resources of such an ECS are in the same resource pool and can be dynamically scheduled.

General Computing-plus ECSs

BMS

BMS offering high-performance computing at low latency for containers.

Instance Family

Node flavors vary depending on regions, and some flavors may be unavailable due to insufficient resources. To obtain available node flavors, log in to the CCE console and switch to the page for creating nodes.

General Computing-plus ECSs

General computing-plus ECSs use dedicated vCPUs and next-generation network acceleration engines to provide powerful compute and network performance.

General Computing-Basic ECSs

General computing-basic ECSs are suitable for scenarios that require moderate CPU performance generally but burstable high performance occasionally while keeping costs low. The performance of such ECSs is constrained by the baseline performance and CPU credits. There are no additional charges for using CPU credits. For details, see CPU Credits.

GPU-accelerated ECSs

GPU-accelerated ECSs provide outstanding floating-point computing capabilities. They are suitable for applications that require real-time, highly concurrent massive computing.

GPU-accelerated ECSs are classified as G series and P series ECSs.

  • G series: Graphics-accelerated ECSs, which are suitable for 3D animation rendering and CAD
  • P series: Computing-accelerated or inference-accelerated ECSs, which are suitable for deep learning, scientific computing, and CAE

AI-accelerated ECSs

AI-accelerated ECSs are dedicated for accelerating AI applications. These ECSs use Ascend processors that feature low power consumption, high compute capabilities, and significantly improved energy efficiency for AI inference and video encoding and decoding.

AI-accelerated ECSs are classified as kAi series and Ai series ECSs.

  • kAi series: Arm ECSs, which use Kunpeng 920 processors
  • AI series: x86 ECSs, which use Intel Xeon processors
