# Nomad vs. Mesos with Marathon

Mesos is a resource manager, which is used to pool together the
|
|
|
|
|
resources of a datacenter and exposes an API to integrate with
|
|
|
|
|
Frameworks that have scheduling and job management logic. Mesos
|
|
|
|
|
depends on ZooKeeper to provide both coordination and storage.
|

|
|
There are many different frameworks that integrate with Mesos;
|
2015-09-20 03:31:33 +00:00
|
|
|
popular general purpose ones include Aurora and Marathon.
|
|
|
|
|
These frameworks allow users to submit jobs and implement scheduling

|
|
|
logic. They depend on Mesos for resource management, and external
|
|
|
|
|
systems like ZooKeeper to provide coordination and storage.

Nomad is architecturally much simpler. Nomad is a single binary, both for clients
|
|
|
|
|
and servers, and requires no external services for coordination or storage.
|
|
|
|
|
Nomad combines features of both resource managers and schedulers into a single system.
|
|
|
|
|
This makes Nomad operationally simpler and enables more sophisticated
|
|
|
|
|
optimizations.
|
|
|
|
|
|
|
|
|
|
Nomad is designed to be a global state, optimistically concurrent scheduler.
|
|
|
|
|
Global state means schedulers get access to the entire state of the cluster when
|
|
|
|
|
making decisions enabling richer constraints, job priorities, resource preemption,
|
|
|
|
|
and faster placements. Optimistic concurrency allows Nomad to make scheduling
|
|
|
|
|
decisions in parallel increasing throughput, reducing latency, and increasing
|
|
|
|
|
the scale that can be supported.
|
|
|
|
|
|
|
|
|
|
Mesos does not support federation or multiple failure isolation regions.
|
|
|
|
|
Nomad supports multi-datacenter and multi-region configurations for failure
|
|
|
|
|
isolation and scalability.
