Bootcamp notes-SLB load balancing
1. Create

80 port
advanced configuration to keep the default
back-end server configuration to select just two ECS, the port is set to 80, weight of 100
about 1 minute to view the configuration has been successful
4. Verify load balancing
Visit the load balancing IP and observe the number of times
that the request is sent to the two servers. Change the weight and verify whether the ratio of the number of times the request is sent to the two servers is the ratio of the weight. The
two are equal, and the load balancing verification is successful.
Session retention function: In a certain period of time, the same client session will only be sent to one server. If
one ecs is abnormal, the load balancer will automatically transfer the request to the normal ecs. The verification method is to close one and then visit the load balancer to verify
