does anyone knows if it's possible to live upgrade machine type or RAM assigned to a VM on GCE so there's no downtime in case one needs additional resources ?
thanks!
There's currently no option for a live upgrade of the machine type or RAM, except during Google maintenance, however you can delete your instance without deleting the persistent disk and then create a new instance choosing the correct CPU type and RAM with this persistent disk. The process is fast and won't cause any loss of data.
Hope this helps.
