Machine Type and CPU Platform

Users can choose different types of cloud servers according to the type and scale of applications they need to deploy when creating a Surfercloud cloud server. At present, Surfercloud cloud server provides the following seven types: Kuaijie O, Kuaijie PRO, Kuaijie Memory, Kuaijie Shared, General, High Frequency, and GPU. Different instances offer different combinations of computation, memory, storage, and network bandwidth. You may flexibly choose cloud servers as you need.

CPU Platform

CPU Platform Overview

The CPU platform attribute refers to the CPU microarchitecture version of the host machine where the instance is located, which includes the following options:

• Intel IvyBridge
• Intel Haswell
• Intel Broadwell
• Intel Skylake
• Intel Cascadelake
• Intel Cascadelake-Refresh
• Intel IceLake
• AMD EPYC2
• Arm Altra

The main difference between each CPU platform is the different hardware architecture and instruction set. The price of instances under the same CPU architecture but different CPU platforms is the same.

You can choose the lowest CPU platform when creating or let the backend fully automate the assignment. For example, when users choose the general type with the CPU platform ≥ Intel Haswell (V3) during creation, the backend scheduling system may schedule the host to a host machine with Haswell, Broadwell, or Skylake platforms.

Best practices for choosing CPU platform

1. The CPU platform is an advanced option when creating an instance, ordinary Web sites/APPs/databases/devops and others that are not heavy computation businesses (CPU average usage rate is less than 30%), as well as those without requirements for the instruction set, are advised to select CPU platform as automatic assignment.

2. For businesses with instruction set requirements (such as software explicitly requiring AVX instruction set), you are advised to choose according to the following table:

3. For businesses with clear computation performance requirements, it is recommended to choose the latest generation available in the current availability zone.
