Cloud hosting - getting my head round it

[Sch09]

Hi Folks,

I'm trying to summarise in my head what cloud hosting is really all about, and I just want to check if this summary is correct:

"Cloud hosting is web server clustering and replication at a virtual level using full virtualisation at the processor cores".

Would that be a fair statement? You then obviously get firewalls, hypervisors, SANS etc - but the main principal comes across as such.

The logic being that it uses up space that in a web cluster would simply stand empty as it would have to be available for one or 2 domains only?

What is a Tier 2 data centre or Tier 4 etc though?

Thanks

Cloud hosting doesn't necessarily say anything about the lowest implementation level. It could be with virtualisation at the processor cores, but it is also possible to do it on other levels.

The Tier classification can be easily found with a search engine like Google [google.com]

Hi there,

What do you mean "lowest implentation level" - are you saying a virtual machine could in itself host a cloud - i.e. be its own hypervisor or are you saying something else - what other levels are you referring too?

Thanks for the Tiers classification info.
