comment init system vs configuration management
I fail to see how one replaces the other. When you say "start a service" using puppet on a systemd system, puppet will just run systemctl start <service>.

comment In Puppet deployment, do all agent nodes have to be connected to an Internet repository?
The master doesn't cache OS package repositories, it just runs the yum/apt, etc command to ensure what you told it to ensure.

comment MySQL slow file I/O
RAM caching won't speed up disk access but will eliminate the need to make as many disk accesses. Typically you don't want your webserver and database on the same host (partly because this means you have 0 room to scale) and you want innodb_buffer_pool to be around 90% of your RAM.

comment puppet agent failing to run automatically
How are you doing the automatic runs? Using the puppet agent deamon? Cron? Mcollective? Are you sure you didn't install both open source and PE puppet?

@kenorb it's suitable but there really is no reason to use it instead of r10k.

comment Bind9 on Ubuntu - SERVFAIL
You only configured facultyportal.test.edu, not facultyprotal.nwcu.edu. Did you run rndc reload or restart named after updating the zone file?

comment Using sar to produce data to graph cpu utilization
If you are going to graph, use something that natively supports it like munin or graphite.
