I am from Cloudways, we have been testing WordPress on different cloud providers in terms of performance, speed and uptime.
We recently integrated Google Compute Engine and tested it in terms of loading speeds. Default WordPress installations give an impressive loading speed, and we think it opens up an entirely new window for WordPress users to host on the cloud that delivers optimum performance.
We have the following setup on GCE servers
1- Nginx (serves static content)
2- Varnish (caches HTTP request)
3- Apache (serves php requests)
4- Memcache (caches database requests)
6- Debian OS
on g1-small GCE instance.
