title: GCP - what are mysql-access instances?
body: <p>I have a Java application deployed to AppEngine Standard and connects to Cloud SQL via public IP. I was looking at VM instances dashboard and found a set of instances with the following naming pattern and these are alerting for high cpu utilization.</p>
  <p>aet-uswest1-mysql--access-{abcd}</p>
  <p>The description says &quot;Anthos/GKE and Dataproc VMs are Google-managed and include built-in agents.&quot;. These are all e2-micro instances and I could not change the instance type. At first I thought these are the underlying AppEngine instances, but the AppEngine instances I use are F4 class, I think these instances are something else.</p>
  <p>What are these instances and how are they used?</p>
  <p>Here is the list I see under instances in VM instances dashboard. I can't ssh or manage these instances. (I have randomized the instance names and ip addresses)</p>
