Using a CVD Instance to Replace VNC and RDP for Remote Desktop Ops
Cloud Virtual Desktop (CVD) offers virtual desktop services featuring on-demand and quick delivery. It uses an encrypted adaptive transmission protocol and policy-based security controls to build a secure portal for business access on the cloud. CVD instances can replace Virtual Network Computing (VNC) and Remote Desktop Protocol (RDP) for efficient Ops and secure R&D, enhancing the security and continuity of business access.

Example: Connecting a CVD Instance to a CVM Instance
Prerequisites
The CVD instance and the target Cloud Virtual Machine (CVM) instance are in the same VPC network, or their private networks are connected via Cloud Connect Network (CCN).
You have purchased and assigned a CVD instance. The end user can log in to it normally. For more information, see Getting Started.
The security group rules of the CVM instance allow access from the IP address of the CVD instance and the required ports. For specific ports, see Common Server Ports.
Example 1: Connecting a CVD Instance to a Windows CVM Instance
Example 2: Connecting a CVD Instance to a Linux CVM Instance
