Having read Microsoft’s document I can draw the following conclusions in summary:
- Microsoft is now using the term ‘OSE’ (Operating System Environment) to describe the ‘thing’ that gets a licence applied to it – this means any entity that runs a Microsoft OS – this could be a physical server, blade or partition or a virtual server or image that is running.
- Use terms for the software licence(s) specify the number of instances of the software that you may run at a particular time rather than the numbers of copies of software that is installed. Each software licence allows you to create and store any number of instances of the software on any of your servers or storage media.
- Microsoft has clarified the 90-day rule and points back to Application Server Licence Mobility guidance
