  <section data-transition="linear" id='node' data-markdown>
    ### Node
    A [node](https://docs.openshift.org/latest/admin_guide/manage_nodes.html) is a machine (physical or virtual) where workloads can be run. Node activity is managed via one or more Master instances.
  </section>

  <section data-transition="linear" id='img' data-markdown>
    ### [Image](https://docs.openshift.org/latest/architecture/core_concepts/containers_and_images.html#docker-images)
    A packaged runtime or workload environment. A bootable linux container that runs wherever Docker is supported.  See also, [`ImageStreams`](https://docs.openshift.org/latest/architecture/core_concepts/builds_and_image_streams.html#image-streams)
  </section>

  <section data-transition="linear" id='container' data-markdown>
    ### [Container](https://docs.openshift.org/latest/architecture/core_concepts/containers_and_images.html)
    A running image with an allocation of system resources.
  </section>
  
  <section id='volume' data-markdown>
    ### Volumes

    * https://docs.openshift.org/latest/dev_guide/volumes.html
    * http://kubernetes.io/v1.1/docs/user-guide/volumes.html
    * http://kubernetes.io/v1.1/docs/user-guide/persistent-volumes.html
    
  </section>

  <section data-transition="linear" id='pod' data-markdown>
    ### Pod
    A group of one or more co-located containers. [Pods](https://docs.openshift.org/latest/architecture/core_concepts/pods_and_services.html) represent your minimum increment of scale.
  </section>

  <section data-transition="linear" id='svc' data-markdown>
    ### [Service](https://docs.openshift.org/latest/architecture/core_concepts/pods_and_services.html#services)
    A service (svc) is a software load-balancer that distributes inbound traffic to associated pods
  </section>

  <section data-transition="linear" id='route' data-markdown>
    ### [Route](https://docs.openshift.org/latest/architecture/core_concepts/routes.html)
    A `service` will receive traffic based on the inbound `Host` header. Similar to how Apache VirtualHosts works.
  </section>

  <section data-transition="linear" id='rc' data-markdown>
    ### ReplicationController
    An [`RC`](https://docs.openshift.org/latest/architecture/core_concepts/deployments.html) is created for every deployment, allowing you to easily scale your workloads by adjusting your desired number of pods
  </section>

  <section data-transition="linear" id='dc' data-markdown>
    ### DeploymentConfig
    A [`DC`](https://docs.openshift.org/latest/architecture/core_concepts/deployments.html#deployments-and-deployment-configurations) helps you define how and when images are distributed to nodes (as pods, containers)
  </section>

  <section data-transition="linear" id='bc' data-markdown>
    ### BuildConfig
    A [`BC`](https://docs.openshift.org/latest/architecture/core_concepts/builds_and_image_streams.html#builds) allows you build new images in a variety of ways

<section id='templates' data-markdown>
    ### Templates
  
    Templates contain a list of objects which document your application composition.  Templates include support for basic parameterization, but may need to be customized per deployment stage.

<section id='example' data-markdown> 
  ### Example App

  A basic Nodejs and MongoDB application:
