Well, we've been in private communication ... but no response yet. So for others that might interested in trying Google Compute Engine ...
First, **don't** install Bitnami's + Moodle offering from Googles MarketPlace. While it sounds good, it ends up being one off for things like updating/upgrading Moodle + it provides their vision of apache/mysql/php and provide no native (yum) way of updating/upgrading any of those.
Not really needed as yum with some added repos will be much much easier to update/upgrade all the parts a pieces that run Moodle. One is much better off using yum with 3rd party repos ... webtatic or remi or epel to acquire PHP and MySQL's own repo to acquire/maintain MySQL.
Google Compute Engine doesn't provide cPanel nor Plesk but one can install Webmin via command line.
Just don't use Webmin default for port 10000 ... GCE projects have a firewall of their own and it's much easier to use port 8080 (Firewall issue) for Webmin.
Webmin is perl based and has a web service of it's own ... + Webmin can update itself ... either via Webmin or via command line. http://www.webmin.com/ + it also has a rather weak terminal via browser but it can be used without having to use the GCE ssh link.
htttp://www.webmin.com/download.html find the link to the .tar.gz download, and use wget in a shell on the GCE instance to xfer the .tar.gz to your Google instance:
The 'trick' to GCE is getting things setup via command line. But, in the GCE Cloud/Project Console there is ssh/open in browser window ssh/terminal access to the instance.
To use root one must use sudo -s.
Once one has access, and sets up the public ip address for site and installs those 3rd party repo's mentioned + Webmin .. it is no different than VPS's on RackSpace, or LiquidWeb, or Host-Ed, or HostGator etc.
GCE can install and use git. So initial install of the moodle via git best.
Already have one there installed the old way? No problem ... side load:

Above is very brief and the reason I mentioned 'not for the tech challenged' ... does require some server admin but it's stuff one will be very glad they learned, IMHO!
