What exactly is the difference between a VPS (Virtual Private Server), a Cloud Server, and a Dedicated Server? I'm having trouble finding a concise explanation that isn't littered with advertising.

I admin a handful of cloud-based (VPS) servers for the company I work for.

The servers are minimal ubuntu installs that run bits of LAMP stacks / inbound data collection (rsync). The data is large but not personal, financial or anything like that (ie not that interesting)

Clearly on here people are forever asking about configuring firewalls and such like.

I use a bunch of approaches to secure the servers, for example (but not restricted to)

  • ssh on non standard ports; no password typing, only known ssh keys from known ips for login etc
  • https, and restricted shells (rssh) generally only from known keys/ips
  • servers are minimal, up to date and patched regularly
  • use things like rkhunter, cfengine, lynis denyhosts etc for monitoring

I have extensive experience of unix sys admin. I'm confident I know what I'm doing in my setups. I configure /etc files. I have never felt a compelling need to install stuff like firewalls: iptables etc.

Put aside for a moment the issues of physical security of the VPS.

Q? I can't decide whether I am being naive or the incremental protection a fw might offer is worth the effort of learning / installing and the additional complexity (packages, config files, possible support etc) on the servers.

To date (touch wood) I've never had any problems with security but I am not complacent about it either.

I know that Xen is usually better than OpenVZ as the provider cannot oversell in Xen. However, what is the difference between Xen PV, Xen KVM and HVM (I was going through this provider's specs? Which one is better for what purposes and why?

Edit:

For an end-user who will just be hosting websites, which is better? From efficiency or other point of view, is there any advantage of one over the other?

I find i am constantly settings up pretty much nearly identical servers and VPSs for a number of my clients and it can be very time consuming. Often the only thing that changes between each deployment is the different website that is to be served. Is there an easy way to automate all this and take the boring monotony of setting up 56 identical servers?

The servers i have deployed so far have only been Ubuntu, but it may be possible that i start to use other linux OSs or even Windows. So far i have looked at Capistrano, but it seems to be focused on writing little ruby programs to do the job with, and i have no knowledge at all
