Microsoft SQL Server Licensing tip

Virtualisation is often thought of as a panacea for saving money. Well, sometimes it does generate cost savings and sometimes it can cost you more money than you were spending before you virtualised. Here is an example of how careful you need to be – if you are using Microsoft SQL Server, you can run several instances of SQL on a single server but the minute you turn the server into a virtual machine you are now obligated to pay Microsoft for a server license for each VM you are using. So if you have 4 VMs running on a server you will need 4 SQL server licenses. Sometimes it can be more cost effective to beef up you hardware using a higher powered processor, more RAM or faster buses rather than virtualizing and having to buy more SQL licenses.
