Machine Type and CPU Platform

When creating a SurferCloud UHost, users can choose different types of UHosts according to the type and scale of the application they need to deploy. Currently, SurferCloud UHost offers the following seven models: Outstanding type O, General Type N. Different models provide different combinations of computing, memory, storage, and network bandwidth, and users can flexibly choose the UHost that matches their business scenarios.

Details of SurferCloud UHost Type:

Model Iteration Information:

• Surfer Series: SurferCloud flagship cloud host series, supporting Network Enhancement 2.0 and RSSD cloud disk, thus the maximum network performance reaches 10 million PPS, and the maximum storage performance reaches 1.2 million IOPS.
• Previous Generation Series: The previous generation of cloud hosts, only supports local disks/ordinary cloud disks/SSD cloud disks. In the available zones where the Surfer series has been launched, the previous generation series will not continue to be supplied.
• Model Integration: The original SurferO, SurferOS, SurferOLITE, and SurferOMAX, these 4 models, have now been unified and merged into SurferO.

Outstanding Type O

1. Overview:
   QuickJ O-Type is a flagship cloud host with excellent computing, storage, and network performance, with a maximum network performance of up to 10 million PPS and a maximum storage performance of up to 1.2 million IOPS. After the integration of the SurferCloud model, QuickJ O-Type now offers two different architectures, namely x86 architecture and Arm architecture CPU platforms. Currently, QuickJ O-Type cloud hosts perform excellently in most scenarios such as web services, game services, and data analysis processing.

2. CPU platform support: Intel Cascadelake(Gold6248); Intel Cascadelake-Refresh(Gold6248R); Intel IceLake(8358P); AMD EPYC2(Rome7542); Ampere Altra(8030).

3. CPU memory combination (supporting ratios from 1:1 to 1:8, different availability zones can choose different ratios, the specific ratio is subject to the creation console)

4. Use Cases:

• Web Services
• Game Services
• Database, Data Analysis
• Internet Components, Android Development
• Applicable to All Scenarios

5. Function Support and Limitations

• Supports Network Enhancement 2.0
• Supports RSSD Cloud Disk Specific selection range:

• Linux's KUHost only supports high kernel version images (i.e., images with kernel version ≥4.19).

General Type N

1. Overview:
   The previous generation model on SurferCloud cloud host. It offers flexible and free combinations of CPU, memory, and disk. Suitable for balanced scenarios of computing, storage, and network.

2. CPU platform support: Intel IvyBridge/Haswell/Broadwell/Skylake

3. CPU memory combination (supporting ratios from 1:1 to 1:8, the specific ratio is subject to the creation console):

4. Use Cases:

• Fully Applicable

5. Function Support and Limitations:

• Network Enhancement 1.0/Network Enhancement 2.0 (Only Skylake and above supported)
• Disk Type Support: Only supports cloud disk, ordinary local disk, SSD local disk

Specific selection range:

CPU Platform

CPU Platform Overview

The CPU platform attribute refers to the CPU microarchitecture version of the host machine where the cloud host is located, including the following options:

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

The main differences between each generation of CPU platforms are different hardware architectures and instruction sets. Under the same CPU architecture, the prices of cloud hosts on different CPU platforms are the same.

When creating, you can choose the lowest CPU platform, or let the backend fully automatically allocate. For example, if the user chooses the general type when creating, the CPU platform ≥ Intel Haswell (V3), the backend scheduling system may schedule the host to the host machine on the Haswell, Broadwell or Skylake platform.

Best Practices for CPU Platform Selection

1. The CPU platform is an advanced option when creating a cloud host. For general web sites/apps/databases/devops and other non-heavy computing services (where the average CPU usage is below 30%), and where there are no specific instruction set requirements, it is recommended to select the CPU platform as automatically assigned.

2. For services that require specific instruction sets (such as software explicitly requiring the AVX instruction set), it is recommended that you make your selection according to the following table:

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