title: How to change the amount of memory in the VM instance, the Compute Engine, and Google Cloud Platform
body: <p>When I create the VM instance on the Compute Engine, I chose the &quot;E2&quot; as the &quot;Series&quot; and the &quot;e2-medium(2 vCPU, 4GB memory)&quot; as the Machine type at the Machine configuration.</p>

  <p>After launching the VM instance, <strong>can I change the amount of memory in the Compute Engine? And, if I can do it, I would like you to share the ways to configure it.</strong></p>
  <p>This is because I'm going to install the WordPress site.</p>
  <p>The number of traffic of the WordPress site will vary between about 2,000 PV per day and 120,000 PV per day.</p>
  <p>With 120,000 PV of traffic per day, the Web server would not be able to respond to all the accesses with the 4GB memory initially set up. Therefore, I want to vary the amount of memory, depending on the number of traffic.</p>
  <p>Thanks.</p>
