• For on-premises environments

• Need identifiable server hardware

• Need access to an identifiable number of sockets and physical cores

• License can be assigned to a physical server

• Allow SQL to be brought to Public Cloud under License Mobility

virtual representations of

hardware threads based on

BYOL Licensing

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

AWS Dedicated Host

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

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

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

Deltek experiences significant annual savings on Microsoft licensing costs

with EC2 Dedicated Hosts

Deltek is an enterprise software and information

solutions provider for professional services firms

and government contractors.

When we moved our SQL Server

licenses to Amazon EC2 Dedicated

Instances, we were able to save 15% on

SQL licensing costs. Additionally, when

we move our Windows licenses to

Amazon EC2 Dedicated Hosts, we will

save 10% on Windows licensing.

• Needed to gain agility, enable innovation, integrate

acquired companies, and save on licensing costs

• Running customer-facing production applications on

AWS for over 20,000 organizations in 80+ countries

• Regulatory compliance a key driver (e.g., FedRamp,

ITAR, SOC)

• Many products integrate with Microsoft SharePoint,

Exchange, and SQL Server

• Keeps pace with global business growth

AWS Dedicated Instance

BYOL: Dedicated Instances

Bring on-premise licenses that do not have SA or that do not qualify for License Mobility

Utilize Windows Server instances that are physically isolated at the host hardware level

Manage expenses by utilizing existing on-premise software

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.

Service Provider Options

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.

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.

Licensing Common Solutions

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.

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.

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
