For most of Azure, AWS stuff I use Ansible for automation and deploying my tools. If I have something like wordpress, joomla or any other classic web application that can be easily run on cPanel, I don't bother with installing automation for them on AWS or any bare servers or even docker. Even though lately using docker, containers or stuff like that have become very popular. Still tons of the stuff like database backup, monitoring, ssh access for each customer, htaccess configuration, php multi-version, etc are not easily done by those technology stacks, cPanel & CloudLinux cover them all. If you want to play it cool, you can even run each web application on heroku. If you're still considering to go out of cPanel stack, I suggest you something like Dokku, deis, Flynn, Docker Swarm, etc... I don't have a blog by myself about this, but there are tons of resource about them how to go with each of them. I mosltly play with Python, Go, Java, NodeJS and some others for web application, so CloudLinux or cPanel are not a fit for me. Therefore I get them done with PaaS as much as I can and tons of help from my Ansible playbooks to run customized machines on bare metal or AWS servers. I started running the web hosting business as a one man show for a 3-5 months to get things running and now we have 2 people on it to manage cPanel/CloudLinux and OpenVZ servers. Thanks for mentioning the monitoring stacks, I'v used some of them before but not extensively. I mentioned "munin" because its available as a plugin for cPanel and sometimes configuring it can cause confusion.
