I want to be able to have a bunch of 512MB CentOS7 servers.....
Can anyone think of a good way to do that?

A bunch? Like how many? Ten, one hundred? What's the end goal? What storage and CPU do you want or need?
-
@scottalanmiller I use very little CPU or Harddrive Space. What I need is RAM
I was thinking about 15 - 20 VMs

Basically a hosted home lab
Basic Web Server
OwnCloud
JumpboxEtc

Well. Let's use 20VMs. If you are talking $5 instances, that's going to be $100/mo. You could buy a small server and go to colo for that price.

For cost effective, a box at home is the best, obviously.

If you don't want VMs, containers are lighter and faster. So pretty much any system where you can run LXC will do nicely.

Yup. Exactly what I do on Vultr, and I have a VM at home for LXC. XO runs in LXC and when a new version comes out, Ansible clones it and updates it for me but leaves the old container. I don't have to do any work at all. Then if a bug happens like the recent backup to NFS bug, I just use the old container.
-
LXC or LXD?

-
With containers I might not need nearly as much RAM

LXD is an LXC interface.
Ubuntu is working on live migration with LXD. That will be awesome.
-
That will be awesome! How do you backup containers?

Just tar the container folder. You can also do file level backups of the containers. LXC by default stores everything in
/var/lib/lxc/so if you want to restore a file tocontainer1you could just cp it back to/var/lib/lxc/container1/root/pathtofolder/ -
@johnhooks Can I do that with the containers running?
-
Can I run different Distros in containers or just the same as the host?

Which file level restore or using tar?

You can run different distros. But I think you need to match systemd and init between host and container though.
-
@johnhooks tar. I assume rsync would work too?
