Mesos doesn’t run one big distributed app across servers in a cluster, but rather interleaves the workloads on nodes in the cluster to maximize the utilization of compute, memory, and I/O resources on the cluster. Mesos can run on bare metal clusters or on machines that have some level of virtualization on them to provide some isolation between workloads running on the same machine. Google did a lot of the original work to create control groups, or cgroups, a lightweight application container for Linux, which is the basis for all LXC containers.
