Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.
I understand that you would like to know the maximum number of concurrent connections that a Private Link Service(PLS) can support.
AFAIK, This is dependent on the service that is exposed via the PLS.
However, I shall check internally once again if there are any limits on Private Link Service concurrent connections and let you know
- In your case, this is the Load Balancer.
- While Load Balancer has a very high limit (the limit is not publicly available), it is designed to handle the maximum capacity of the backend pools.
- The bottleneck actually arrives at the number of concurrent requests your backend can handle.
- NOTE : LB only load balances the connection, the backend VMs should be capable of accepting the connections if it grows in large number.
- Now, for a individual VM , you can find the limits on Flow limits and active connections recommendations
VMs that belong to a virtual network can handle 500k active connections for all VM sizes with 500k active flows in each direction.
Cheers,
Kapil.
