Site, not instance cloud computing options?.

What are the different site cloud computing options out there? (aka, I'm not "launching" and managing instances but instead I'm just treating it as "one" server that can grow into whatever I need it to)

i've noticed with many cloud providers, they have "public" cloud products and "private cloud" products. the public usually refers to a la carte cloud servers. whereas, private refers to a private infrastructure (ie an ESX Host where you can deploy multiple instances).
some providers just call all of their servers "instances." so, you can just deploy one instance and use it like a site.

if the cloud product features high availability, then you will have an extra layer of protection from downtime. if the physical host on which your cloud server resides happens to fail, then the cloud server will migrate to another physical host and reboot. the cloud server will be down for a minute or so while it reboots.
if you have fault tolerance, then you will not suffer any downtime at all. with fault tolerance, you have 2 identical VMs running lockstep on 2 different physical hosts. if one host fails, then the other one is already there for instant failover. fault tolerance is usually an expensive option since it requires double the amount of cloud servers to run your services.
