 ## Introduction
-PrivateLink is a highly available, scalable technology that you can use to privately connect your VPC to TDengine service as if they were in one VPC. PrivateLink allows the resources in your VPC to connect to TDengine service using your private IP addresses, and does not expose your data to the public internet.
+PrivateLink is a highly available, scalable technology that you can use to privately connect your application to TDengine Cloud instance with different VPCs. PrivateLink allows the application in your VPC to connect to TDengine Cloud instance through your private IP addresses, and no needs to expose your data to the public internet.
