i have manually operated multiple JVM per server, maintaining /etc/services to track the ports, and apache+modproxy as front end. start/stop services and let apache detect the active state. with mesos and cgroups we get even more a dynamic assurance that services have the minimum guaranteed resources and access to scale across the entire compute cloud. we will soon be able to scale up/down on demand maintaining an 85% or greater utilization reducing allocation. with cgroups we remove the overhead of multiple OS that traditional VM brings.
