I've updated that question to include information on PaaS. – paulmorriss Aug 28 '12 at 10:02

Shared hosting is one server hosting multiple sites or resources.

"Platform as a service (PaaS) is a category of cloud computing services that provide a computing platform and a solution stack as a service." ~Wikipedia

They're actually the opposite.

Could you go into more detail on how they are opposite? – Abe Miessler Aug 27 '12 at 19:00
    
@AbeMiessler - Well, Shared hosting is putting multiple customers on one server. PaaS is putting one "resource" across an infrastructure, which utilizes multiple servers. The first is for economical efficiency in terms of the most utilization of hardware. The second is also efficient, but because it's very easily scalable. – ionFish Aug 27 '12 at 21:41
