Unusual peaks of 100% CPU usage in amazon EC2 instance

I have very unusual peaks at my Amazon EC2 CPU usage and network in/out simultaneously.

This is the CPU usage: CPU usage

THis is the Network in: Network in

And my network out: Network out

How can I know what process, file or command is doing this?

How can I recognize the problem and solve it?

This is something that I would use top/htop for and/or ps aux for. However, with your issue, you will likely have to be watching the server at the times in which these spike occur so top or htop are probably better options. I would likely think that there is a cron that would be causing this as it appears that you have something occurring every hour. so take a look in /etc/cron.hourly as once you see the spike see if it references anything from that directory.
