### Terminology

1. [node](#/node)
2. [image](#/image)
3. [container](#/container)
4. [pod](#/pod)
5. [service](#/se)
6. [route](#/route)
7. [replicationController (rc)](#/rc)
8. [deploymentConfig (dc)](#/dc)
9. [buildConfig (bc)](#/bc)
10. [template](#/template)

  </section>

 <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='image' 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 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='se' data-markdown>
    ### [Service](https://docs.openshift.org/latest/architecture/core_concepts/pods_and_services.html#services)
    A service (se) 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>

  <section data-transition="linear" id='template' data-markdown>
    ### Template
    [Templates](https://docs.openshift.org/latest/architecture/core_concepts/templates.html) provide an easy way to create a set of resources using customized paramters.
