一个Google云端平台项目中的Google Compute引擎上可以运行多少个WordPress实例。

Question

i was wondering if anyone knows how many instances of a WordPress site i can potentially run on a n1-standard-4 vm instance on the google compute engine either using compute engine or the container engine with docker. is there a way to run benchmarks to figure this out.

Answer 1

An easy way to get a rough estimate for Google Container Engine would be to run the WordPress tutorial with a minor modification: in the cluster create command, use --machine-type=n1-standard-4 . Then after following the guide to spin up a replication controller-backed wordpress pod, scale it by running

kubectl scale rc wordpress --replicas=100

and see how many replicas get scheduled. Keep in mind that this will just give you a rough estimate of how many instances you can run on an n1-standard-4 gated by cpu/memory. If you actually wanted to run multiple WordPress instances with persistent storage backing, you would follow this guide and repeat n times for as many as you want.
