When it comes to running Microsoft Windows Server or Microsoft SQL Server in AWS, there are currently three options regarding licensing:

  • Simply pay the normal AWS fee for Windows Server instances (on-demand, spot, reserved). These fees are typically more than same-sized instances of other operating systems. See: https://aws.amazon.com/windows/resources/licensing/#launch
  • Provision an AWS Dedicated Host (https://aws.amazon.com/ec2/dedicated-hosts/) and use the existing Cornell Microsoft licensing (http://www.it.cornell.edu/services/software_licensing/available/windows.cfm). This is because the existing Cornell Microsoft licensing is limited to computers “owned” by Cornell. Microsoft considers instances running Windows software running on Cornell-provisioned AWS Dedicated Hosts as “owned” by Cornell (not so for instances running elsewhere on AWS). https://aws.amazon.com/windows/resources/licensing/#dedicated
    • Dedicated Instances are a separate AWS offering. Our campus Windows license does not work with dedicated instances, only dedicated hosts. Also please note that there is a $2/hr (~$1500/mo) charge for running any number of dedicated instances, per-region (not including the cost of the instances themselves).
  • As of April 2018, Microsoft will no longer allow any form of Bring-Your-Own-License (BYOL) to AWS Relational Database Service (RDS). This means that Cornell cannot use our campus Microsoft licensing agreement for Microsoft SQL Server on RDS. For details see 2018-04-27 AWS & SQL Server RDS Licensing.
    • For MS SQL Server running in AWS RDS, you can use License Mobility: https://aws.amazon.com/windows/resources/licensing/#mobility. 
      • Two BYOL forms will need to be completed on your behalf by the Cloud Team. Please contact at cloud-support@cornell.edu to begin that process.
      • See the diagram below for setting BYO licensing for Microsoft SQL Server to AWS RDS. The "Licensing Mobility" has already been worked out between Cornell and Microsoft (and AWS) so selecting "bring-your-own-license" and checking the "I acknowledge..." box should be all you need to do.
      • The RDS pricing page shows pricing separately for BYO licensing: https://aws.amazon.com/rds/sqlserver/pricing/
