# Nomad vs. Kubernetes
|
||
|
|
|
||
|
|
Kubernetes is an orchestration system for Docker developed by the Cloud Native
|
||
|
|
Computing Foundation (CNCF). Kubernetes aims to provide all the features
|
||
|
|
needed to run Docker based applications including cluster management,
|
||
|
|
scheduling, service discovery, monitoring, secrets management and more.
|
||
|
|
|
||
|
|
Nomad only aims to provide cluster management and scheduling and is designed
|
||
|
|
in the Unix philosophy of having a small scope while composing with tools like [Consul](https://consul.io)
|
||
|
|
for service discovery and [Vault](https://www.vaultproject.io) for secret management.
|
||
|
|
|
||
|
|
While Kubernetes is specifically focused on Docker, Nomad is more general purpose.
|
||
|
|
Nomad supports virtualized, containerized and standalone applications, including Docker.
|
||
|
|
Nomad is designed with extensible drivers and support will be extended to all
|
||
|
|
common drivers.
|
||
|
|
|
||
|
|
Kubernetes is designed as a collection of more than a half-dozen interoperating
|
||
|
|
services which together provide the full functionality. Coordination and
|
||
|
|
storage is provided by etcd at the core. The state is wrapped by API controllers
|
||
|
|
which are consumed by other services that provide higher level APIs or features
|
||
|
|
like scheduling. Kubernetes supports running in a high available
|
||
|
|
configuration but is operationally complex to setup.
|
||
|
|
|
||
|
|
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 a lightweight resource managers and a sophisticated scheduler
|
||
|
|
into a single system. By default, Nomad is distributed, highly available,
|
||
|
|
and operationally simple.
|
||
|
|
|
||
|
|
At the time of writing, Kubernetes targets managing 100 node clusters and supports
|
||
|
|
only a single region. Nomad is designed to support clusters several orders of magnitude
|
||
|
|
larger and supports multi-datacenter and multi-region configurations.
