Overview of CVD Instance Specifications
The specifications of a Cloud Virtual Desktop (CVD) instance include computing resources (vCPU and memory) and storage resources (system disk and data disk). Their combination determines the CPU, memory, GPU, system disk, and data disk configurations of the CVD instance. Different instance types provide different computing capabilities, making them suitable for various CVD business scenarios.
Computing Resources
Specification Name | vCPU | Memory | GPU | Recommended Scenario |
CVD - Standard S1_4-core 8 GB | 4vCPU | 8G | - | Basic OA office work |
CVD - Standard S1_4-core 16 GB | 4vCPU | 16G | - | OA office work |
CVD - Standard S2_8-core 16 GB | 8vCPU | 16G | - | High-performance office work and code development |
CVD - Graphics G1_4-core 16 GB | 4vCPU | 16G | 1/4 NVIDIA T4 | Light 3D workloads, such as drawing viewing |
CVD - Graphics G1_8-core 32 GB | 8vCPU | 32G | 1/2 NVIDIA T4 | Moderate 3D workloads, such as online design |
CVD - Graphics G1_16-core 64 GB | 16vCPU | 64G | 1 NVIDIA T4 | Heavy 3D workloads, such as video editing |
Note:
Computing resources of CVD instances will be continuously planned and added.
Storage Resources
The storage resources for a CVD instance consist of the system disk and the data disk, each backed by a cloud disk. You can choose between Cloud SSD or Premium Disk. Select the disk size based on your requirements.
Category | Description |
System disk | It is similar to the C drive in Windows systems. The system disk contains a full copy of the image used to launch the instance, as well as the running environment. When the instance is launched, the size of the system disk must be larger than that of the image used for launch. |
Data disk | It is similar to the D drive in Windows systems. The data disk stores user data. |
CVD Images
An image is a template containing the software configuration (such as the operating system and pre-installed programs) for a CVD instance. Tencent Cloud images provide all the information required to launch CVD instances. Users need an image to start an instance. One image can be used to launch multiple instances repeatedly. An image is essentially the installation disk for a cloud server.
Tencent Cloud provides the following types of images:
Category | Description |
Public image | Available to all users, providing a pre-configured CVD operating system. |
Custom image | Dedicated CVD images can be created, enabling administrators to implement batch purchase operations based on specific requirements. |
Access Portal
The access portal for CVD is a browser-based secure portal. End users receive a link through email or SMS. After completing login authentication, they can access the CVD resources assigned by the administrator.
CVD Policies
A CVD policy is a set of security rules that define configurations such as file redirection, peripheral redirection, clipboard read/write permissions, and watermarks. It is used to uniformly control the access permissions of end users when they use a CVD instance.
