Anaconda platform components run on clusters, which are groups
of machines listed in a cluster profile.

Cluster profile
===============

A cluster profile defines the cluster's name, its machine nodes
and other options such as security and network settings.

One are more cluster profiles are defined during Adam
:doc:`installation <../install/index>`, just before creating the cluster.

Cluster profiles are located in the
``~/.continuum/adam/profile.d/`` directory.

A cluster definition identifies information about a running
cluster, including the cluster name, nodes in the cluster and
other platform component options. Cluster definitions are
located in the ``~/.continuum/adam/cluster.d/`` directory.
