title: What's the difference between Google's Borg and Google's Kubernetes and Docker
body: <p>As I know, Google's Kubernetes is based on Google's Borg; however, it seems like Borg is larger than Kubernetes. My understanding is that Borg is a large system containing a sub-system like Kubernetes and its own containers like Docker.</p>
  
  <p>So, I would like to know:</p>
  
  <p>1) In term of containers cluster management, what's the key difference between Borg (sub-system inside) and Kubernetes?</p>
  
  <p>2) In term of container technology, what's the key difference between Borg (sub-system inside) and Docker?</p>
