Excellent points Sam and i completely agree except with regards OS virtualisation, i actually believe this will eventually die out, as paravirtualisation technologies such as Xen offer so much more in terms of functionality and management to the end-user, than users that are stuck sharing the same OS instance.

As I was just saying (see “Bare Metal” cloud infrastructure “compute” services arrive, there will be three primary types of compute resources available in the coming era of cloud computing:

– physical machines
– virtual machines
– OS virtualisation

Currently (in cloud at least) most of the focus is on VMs and systems like Cisco’s UCS will ensure that this is a vibrant market and compelling option.

However we haven’t heard anywhere near enough about OS virtualisation (what you guys generally call VPSs, where multiple users share the same OS instance) and I think there will be more automation in the provisioning of bare metal too (as evidenced by SoftLayer’s announcement this week).

Ultimately the user doesn’t [need to] care *how* you as a provider manage to execute their workload, provided you do it withing price, performance and other metrics. You could use an army of monkeys if that worked for you.

That’s the beauty of cloud – the devil’s in the details and the details are someone else’s problem now.
