In prior versions of Windows Server choosing the right version determined what technical capabilities the server provided. Some versions had clustering some did not, and some just had IIS. When planning for your server infrastructures, you looked at the functionality of the servers before you looked at what you needed to purchase. After that you then delved into the joy of licensing of the servers. With Windows Server 2012, the conversation is a bit easier now. There are just two main versions, Standard and Datacenter. What makes this a fun conversation is that both versions have the same technical capabilities. The main difference is licensing for virtualization rights.
