title: What is different between cpu vs. requests.memory, pods vs. count/pods
body: <p>When I studying about <a href="https://kubernetes.io/docs/concepts/policy/resource-quotas/" rel="nofollow noreferrer">Resource Quotas</a>, I found somethings very similar, e.g:</p>
  
  <ul>
  <li><code>memory</code> vs. <code>requests.memory</code></li>
  <li><code>pods</code> vs. <code>count/pods</code></li>
  </ul>
  
  <p>So, my question is what's the different between them?</p>
