I have the following setup.
2 x gce n1.standard instances running nginx/php5-fpm
1 x cloud SQL d8 instance with both GCE instances connected to it.
The front end servers are running a stripped down version of osCommerce-2.3.3.4 with NO admin section on the front end. Its just the catalog portion of osC.
I ran a load test with load impact, and the site is unusable at around 50-100 users. I am only looking to support at absolute max 500/users at any give time. We average around 130-170 on our current server.
I am not looking for a complete explanation but any helpful places to check, things to try, stuff to read, I just need a direction to go in to get this cloud platform working like we wanted.
Thanks in advance.
