Great news for service providers, Microsoft announced this week that RDS will have Software Assurance (SA) mobility rights! This is a great move, it will allow service providers to have shared hardware, but dedicated VM’s (just like others under the license mobility program). Customers can leverage their existing volume licensing agreements (with software assurance) to install RDS in your datacenter.
Pay attention to which products are eligible for license mobility. The products that are allowed are located in the Product Use Rights (PUR) not the SPUR, as this is a volume licensing use right, not SPLA. To download a copy click here Service providers would still be required to report Windows under their SPLA agreement. Last, make sure your customers have active software assurance for all licenses used for license mobility!

Can you explain or give some clue about licensing 10 remote desktop users using spla? These users will connect to windows 2012 server std. edition.

Yes, every user that has access to RDS will need to be reported. You will also need a processor license for all physical processors on the server for Windows STD. Please read virtualization rights for Windows on this site to ensure you are licensing it correctly from a virtualization perspective. If you are referencing mobility, you will first need to sign the ability addendum from your reseller. Secondly, ensure your customer has active Software Assurance for the RDS licenses. You will then be able to deploy RDS in a shared hardware, dedicated VM for that customer. Check out https://splalicensing.com/category/rds/
