Is Routing Mesh a Load Balancer?
Routing Mesh is not Load-Balancer. It makes use of LB concepts.It provides global publish port for a given service. The routing mesh uses port based service discovery and load balancing. So to reach any service from outside the cluster you need to expose ports and reach them via the Published Port. In simple words, if you had 3 swarm nodes, A, B and C, and a service which is running on nodes A and C and assigned node port 30000, this would be accessible via any of the 3 swarm nodes on port 30000 regardless of whether the service is running on that machine and automatically load balanced between the 2 running containers. I will talk about Routing Mesh in separate blog if time permits.
