Service Discovery	Yes	Service	Yes (multiple: DNS-based and proxy-based/L4 load balancer)
Dynamic Scaling	Services, Distributed Application Bundle, Stack	Replica Set, Replication Controller, Deployment, Horizontal Pod Autoscaling	Marathon app spec (instance count) and multiple options
Exposing a service	Routing mesh	type=LoadBalancer in Deployment	Multiple (direct placement on public agent or, preferred, via Marathon-LB
