title: Can we use Unmanaged Instance group for external HTTPS load balancer in GCP
body: <p>I am planning to create an External HTTPS load balancer on GCP but in my use case there are no identically configured VMs and i need to make sure it should be a highly available (HA) setup.</p>
  <p>So as no identical VMs i am planning to go with Unmanaged instance group(for backend-service configuration in LB) but in gcp documentation it is mentioned that unmanaged instance group is not suitable for HA.</p>
  <p>can you help me out which approach we need to choose for this use case?</p>
  <p>Thanks in advance...</p>
