- Every instance creating some boot disk (based on the conditions from instance template)& external IP . and CPU scales then VM itself delete including boot disk & IP.
I thought autoscaling only adds CPU resources but adding extra disk. where new data added to the website stored I mean which instance among them & None of them are permanent. it can be useful only power up an image or snapshot.
To overcome this issue we need to automate snapshots. I am not a developer but just confusing here.
We can create load balancer to existing instance too instead of instance group.
