12. BYOL Licensing

13. Bringing Licenses to AWS
BYOL is the process of bringing volume licenses
to dedicated hosts or instances.
Advantages:
• Take advantage of the efficiencies of the
AWS Cloud while utilizing existing
investments in on-premise software
• Extend the lifecycle of prior software versions
• Import your existing Windows images to the
AWS Cloud

14. AWS Dedicated Host

15. BYOL: Dedicated Hosts
Bring on-premise licenses that do not have SA or that do not qualify for License Mobility
Take advantage of AWS Linux compute pricing
Manage expenses by utilizing existing on-premise software
Maintain control and visibility into physical core and processor count
Customer defines which host it will be running on for its placement and declares an
affinity between the instance and the host

16. Comparing Dedicated Hosts to Standard EC2 Instances
 Single-tenant servers host instances for only
your workloads (1 AWS Account)
 You can determine which host instances run on
 You pay per host
 You can continually reuse the same physical
server through targeted placement, or let EC2
place your instances automatically
 Visibility into physical cores and sockets

17. Dedicated Host: Licensing Models
Dedicated hosts allow for:
 Windows Server BYOL
 MSDN
 Maximum virtualization using Windows Datacenter and SQL Enterprise
 User and server based licensing deployment
 Passive failover for SQL when Software Assurance is active

18. Dedicated Hosts: Licensing Models
Microsoft Product Terms allow for dedicated outsourcing
Outsourcing Software Management
Customer may install and use licensed copies of the software on Servers and other
devices that are under the day-to-day management and control of third parties, provided
all such Servers and other devices are and remain fully dedicated to Customer’s use.
Customer is responsible for all of the obligations under its volume licensing agreement
regardless of the physical location of the hardware upon which the software is used.
Customer must bring Windows Server. License Included is NOT available
Customer must host (or connect to) a Windows Key Management Server

25. Dedicated Instances: Licensing Models
Dedicated Instances allow for:
 MSDN deployment
 User based BYOL options including Windows Desktop OS and Microsoft
Office
 BYOL SQL Server Virtual OSEs
 BYOL Windows Server Licenses NOT eligible

26. Dedicated Instance: Configuration Options
This is a subset for example purposes. Full list of configurations
available at: https://aws.amazon.com/ec2/purchasing-options/dedicated-
instances/
SQL Server is licensed by vCPU with
a four core minimum per instance.
Customer brings enough cores to
cover vCPUs on desired instance
size.
Software Assurance not required.
User based products can be deployed
on dedicated instance without regard
to vCPUs.

27. Service Provider Options

28. Use your own SPLA
 The Service Provider License Agreement (SPLA) is intended for customers offering software as a
service to third parties.
 Common scenarios include web hosters, ISVs, application service providers.
 SPLA is pay as you go with no upfront commitments.
 SPLA licenses can be used on shared tenancy for all user (SAL) based applications.
 AWS is referred to as a “Data Center Provider” in the use rights (SPUR).
 SPEligible products include Microsoft Office, Remote Desktop Services and Exchange.
 UR designates products eligible to be run in AWS shared tenancy as “DCP eligible”.
 SPLA products licensed by core or physical processor can be deployed on dedicated hosts.

29. Self Hosted Application Licensing
 If a customer’s application qualifies for self hosting under Microsoft Product Term language,
customers can use their volume license agreement to offer software as a service.
 This benefit is described in the Software Assurance Section of the Microsoft Product Terms
with very specific language.
 Deployments utilizing self hosted licensing benefits can be deployed on AWS. Windows
would be purchased from AWS, all other products in solution would be purchased from
Microsoft with Software Assurance.
 License mobility is what enables these scenarios to be deployed on AWS.

30. Licensing Common Solutions

31. Licensing Failover Servers
With SQL 2014, passive failover benefits in the public cloud became available for customers with
active Software Assurance (SA).
Customers with active Software Assurance receive this benefit when bringing SQL Server to AWS.
Without Software Assurance, both active and passive servers must be separately licensed.
If the active instance is using dedicated hardware, the passive is required to be on dedicated
hardware. If the active instance is on 3rd party shared servers the passive is required to be on
shared servers.
Customers do not need to buy additional SQL licenses for the passive instance, however they will
need to acquire Windows Server and compute to run the passive instance.

32. Licensing for Common Microsoft Solutions
Exchange Server is eligible
for License Mobility under
the Software Assurance
program.
A license must be assigned
for each instance of the
server software that is being
run.
There are two main
licensing models that apply
to SQL Server:
• Server+Client Access
License (CAL)
• Per Core licensing
SharePoint Server is
eligible for License Mobility
under the Software
Assurance program.

33. Mixed Licensing Model is a Win-Win situation
 Use BYOL for core (slowly varying) infrastructure
 Large potential savings by reusing licenses
and
 Use License Included for varying infrastructure
 Take advantage of AWS Auto Scaling
 Less management overhead, pay-as-you-go
