I am trying to understand how can i use canary testing with a managed instance group,
from what i learnt so far i do need to create an instance template and an instance group based on the new code changes i made, my question is : do i have to use the same Load-balancer and add the new instance group (canary instances) as a back-end and then distribute the traffic over the old instance group and the new one.
or is there any option to use the old Managed instance group to roll updates into part of the instance group and in case of success roll updates to the rest. Thank you
