I have my 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.
aet-uswest1-mysql--access-
The description says "Anthos/GKE and Dataproc VMs are Google-managed and include built-in agents.". 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 for F4 class, I think these are something else.
What are these instances and how are they used?
