I suppose this is really quite a general question, but it would be good to maybe get a discussion going on this.
These days there's a definite urge to virtualise everything - the advantages are clear, but I can't help wondering if it's always appropriate to do so. Some people, for example, think it's a good idea to put every service into its own container so that you have your BIND in one container, your Apache in another, and so on, but isn't there significant overhead in this approach? Even if you're not bothered about creating self-contained services like this, do you put everything in a virtual instance these days just because it makes backup easier perhaps? If you were running a production website on a dedicated machine would you virtualise it even?
