(I was part of a preferred AWS solution provider shop that demonstrated AWS' enterpriseness.) Pair (US), ByteMark (UK) and Linode (global) are top choices for budget stuff. ByteMark has setup VMware boxes with freenas storage for us in the past. (For us being sysadmins, budget dedicated is way cheaper than AWS.). Pair and Bytemark support are top notch. For enterprisey stuff self-service/remote hands/support... OpSource, SoftLayer and RackSpace. Also the killer cost in a datacenter is power followed closely by labor, so reducing needs by using the simplest / COTS solution can be much cheaper. Servers tend to sprawl, not decrease... So cull viciously.
