Yes, a load balancer can typically be bound to machines in other VPCs, depending on the cloud provider's network architecture and configuration. This is often achieved through VPC peering, private networking, or cross-VPC connectivity features.
For example, in Tencent Cloud, you can use VPC Peering Connection to link two VPCs within the same region or across regions. Once the peering is established, the load balancer in one VPC can distribute traffic to backend servers in the peered VPC.
Example:
In Tencent Cloud, services like CLB (Cloud Load Balancer) support cross-VPC backend binding when proper network connectivity is configured. Additionally, Tencent Cloud Private Network (VPC) and Peering Connection ensure secure and low-latency communication between VPCs.
