Hello, I have installed ISPConfig 3 into EC2 instance with 1 vCPU and 1GB RAM for testing, I just created one domain for this testing, now the 1GB RAM almost used, any hardware requirement for reference? Thanks
ISPConfig 3 dos not use any hardware resources permanently as it is not a daemon. ISPconfig is just a web interface plus a script that starts once a minute, it uses just a few megabytes of ram. The resources on your server are used by apache, mysql, the mail system etc. For a full server with all services (web, mail, dns) installed you should have at least 1 GB ram. The traffic does not matter much for the ram consumption, only if you have ten thousands of requests per hour, then traffic matters again.
