[HDGEM] Azure Load Balancer uses a hash-based distribution algorithm.

By default, it uses a 5-tuple hash composed of source IP, source port, destination IP, destination port, and protocol type to map traffic to available servers. It provides stickiness only within a transport session. Packets in the same TCP or UDP session will be directed to the same instance behind the load-balanced endpoint. When the client closes and reopens the connection or starts a new session from the same source IP, the source port changes. This may cause the traffic to go to a different endpoint in a different datacenter.
