say I have a 3 node LXD cluster running under a load balancer. Traffic begins ramping up and I need to scale horizontally by adding another node into the cluster. At this point, I have a 4-node cluster under the LB.
In what ways in this approach beneficial? I'm trying to understand if it reduces the load of the overall baremetal that contains the nodes or just allows for more requests to process. In the case that it's more requests that are allowed to process through, would I want to me measuring the load average of each individual container?
