Managed instance groups to re-use boot disks
Apologies is this functionality exists, but can't see any options to allow it.
To reduce the boot time of autoscaled MIG's would be great if the boot disks from previous instances which have been set to not auto delete would be re-used. This would avoid the 1 minute odd provisioning time on a windows host hopefully.
Basically bring back online previous hosts in the mig, hosts in the MIG could also be numerically numbered from 1 > 1000 .
