title: Do the capabilities of EC2 instances scale proportionately?
body: <p>Say I have three options:</p>
  <div class="s-table-container">
  <table class="s-table">
  <thead>
  <tr>
  <th>Instance type</th>
  <th>vCPU</th>
  <th>Memory (GiB)</th>
  <th>Bandwidth (Gbps)</th>
  <th>Price</th>
  </tr>
  </thead>
  <tbody>
  <tr>
  <td>Small</td>
  <td>A</td>
  <td>B</td>
  <td>C</td>
  <td>D</td>
  </tr>
  <tr>
  <td>Medium</td>
  <td>2A</td>
  <td>2B</td>
  <td>2C</td>
  <td>2D</td>
  </tr>
  <tr>
  <td>Large</td>
  <td>4A</td>
  <td>4B</td>
  <td>4C</td>
  <td>4D</td>
  </tr>
  </tbody>
  </table>
  </div>
  <p>What are the implications of running 4 small instances vs 2 medium vs 1 large? Is one better or are they the same?</p>
  <p>I am very new to all of this, thanks in advance.</p>
