First time I reached the front page I had ~250 concurrent users and increasing, then the server crashed.

After that I wrote a cronjob that runs a script which automatically increases my virtual machines RAM. When I have little or no visits it uses 1GB RAM the most it went up to was 9GB RAM (increasing with 1GB at a time).

It also sends me an e-mail when increasing/decreasing the RAM so I can ensure that it doesn't crash.

I also use Wordpress with caching enabled and the above helps me keep the costs down, don't want the server to run on 8GB RAM all the time nor 1GB RAM.

Which provider is that? AWS? I feel like it's only a matter of time before auto-scaling works well enough that it's just a standard feature.
