I am looking to get Microsoft Azure to run Sharepoint on, and I intend to use a virtual machine. Right now, I am trying to figure out what size of virtual machine to get, and how many. According to this web site: http://technet.microsoft.com/en-us/library/cc262485.aspx, I need a web server with 8GB of RAM and a database server with probably 16GB of RAM. But, when looking on Azure's website, I don't see anything about servers, I just see virtual machines, and SQL databases. So this is why I am wondering how many virtual machines, and what size, it will take to run Sharepoint. Thanks.

Windows Azure Virtual Machines are what you'll want to look at. Windows Azure doesn't actually provision a physical server for you; the entire cloud is virtualized. So: for a software product recommending 8GB, that would roughly equate to a Large VM size (7GB usable, 4 cores).
You can always change a VM's size later, so you may want to start with Large instead of Extra Large (XL), which provides 8 cores and 14GB usable.
