Because, different services could operate on the same LB, concurrent execution could result in conflict or unexpected result. For AWS and GCE, they apparently doesn't have the problem, they use one LB per service, no such conflict.
 
 There are two load balancers per availability set internal and external. There is a limit on number of services that can be associated with a single load balancer.
-By default primary load balancer is selected. Services can be annotated to allow auto selection of available load balancers. Service annotations can also be used to provide specific availability sets that host the load balancers. Note that in case of auto selection or specific availability set selection, when the availability set is lost incase of downtime or cluster scale down the services are currently not auto assigned to an available load balancer.
