Windows server 2016 datacenter rds cals free. The Essentials of Windows Server Licensing for Virtual Machines
Windows Server Standard : Used for physical servers or environments with minimal virtualized requirements. It serves as a critical security component in protecting the transport key, and works in conjunction with other Windows Server components to ensure high security levels for Shielded VMs. Figure 2. Windows Server Essentials : Ideal for small businesses with no more than users and 50 devices. This edition is also a great replacement for businesses running Windows Server Foundation as the same edition is not available for Windows Server Windows Server MultiPoint Premium Server : Allows multiple users to share a single computer while having their own applications and Windows experience and is suitable for academic environments.
Windows Storage Server : Suitable for dedicated storage solutions. This is a stand-alone product that runs directly on the bare-metal server and is built using the same technology as the Hyper-V role on a Windows Server Readers can also download here the Free Microsoft Windows Server Licensing Datasheet that provides additional useful information.
The table below shows the licensing model adopted by each Windows Server edition:. Licensing Model. CAL Requirements. Windows Server Datacenter. Windows Server Standard. Windows Server Essentials. There are many limitations in this edition. Windows Server Essentials does not support virtualization. Client access licenses are not required.
Windows Server Essentials is well-integrated with Office hosted services. In other words, you can install Windows Server Standard on a host machine and run two virtual machines with Windows Server Standard as a guest OS.
Windows Server Standard running on a host used for virtualization as a hypervisor can be used only to install Hyper-V to run VMs. Using the host OS as a full-featured server with two virtual servers is not allowed. You cannot use three full-featured servers one physical and two virtual if you have the Standard license that covers two VMs and one physical server. The licensed Datacenter edition covers Windows Server installed on a host and allows you to run an unlimited number of virtual machines with Windows Server installed as a guest OS.
A Windows Server Essentials vs Standard comparison is outside the scope of this blog post. CAL licenses are required for both Standard and Datacenter editions. For example, if you have licensed Windows Server Standard for all processor cores of a physical server and install Windows Server Standard on a host with the Hyper-V role enabled, then you can run two VMs with Windows Server Standard. If you need to run 4 virtual machines on a server, then you need to buy one more license a set of two-core licenses to cover all cores for this server the total number of VMs is four and Windows Server Standard is used in this example.
One Standard license covers two virtual machines. If you need to run 4 VMs on a physical server that has two 8-core processors, you must buy 16 dual-core Standard licenses for Windows Server Two license sets cover all cores twice and allow you to run 4 VMs. If you need to run an odd number of VMs on a host, you need to buy licenses for the next even number of VMs. If you need to run 4 VMs on the same physical server that has two 8-core processors but with the Windows Server Datacenter license, you need to buy 8 dual-core Datacenter licenses for Windows Server VM licensing order: Physical cores must be licensed first and only after that virtual machines must be licensed.
Taking into account the current price for Windows Server licenses, it may be better to buy Windows Server Standard licenses if you are going to run up to 12 virtual machines on a single physical server.
If you need to run 14 VMs or more, the more rational decision is to buy Windows Server Datacenter. VM migration is especially needed if you run VMs in a cluster.
In this case you need to buy the number of licenses to cover all VMs on all hosts for each physical server as if you are migrating all VMs from all hosts to one host. In this case, each VM is licensed to migrate to any host.
You can migrate a Windows Server license between physical servers once every 90 days. The Hyper-V virtual machine activation binds to the activated instance of Windows Server installed on a physical server that acts as a hypervisor. Virtual machines can be activated without an internet connection.
There is no need to manage product keys for VMs. Activation is preserved if licensed VMs are migrated between licensed hosts. We have two physical servers. Each server has one 6-core processor. Two VMs must run on each server. Windows Server Standard license can be used. We need to buy 8 dual-core licenses for each server because it is not possible to buy less than 8 double-core licenses to license a physical server even if there are less than 16 cores. Note: VMs used in examples are running Windows Server of the edition mentioned in the corresponding example.
Each server has one core processor. However, Dedicated Hosts provide additional control over your instances and visibility into Host level resources and tooling that allows you to manage software that consumes licenses on a per-core or per-socket basis, such as Windows Server and SQL Server. In addition, AWS Config will keep a record of how your instances use these Dedicated Host resources which will allow you to create your own license usage reports.
In order to take full advantage of EC2 it is recommended that customers first consider bringing eligible licenses through License Mobility. Default tenancy EC2 allows customers to scale capacity up and down according to changing needs. This allows customers to pay only for what they use. Dedicated Hosts are most cost effective when the host is highly utilized and in a steady, non-variable state. A Dedicated Host will support the BYOL scenarios outlined in this FAQ and provide customers with more control and visibility over how their instances are placed, which is useful for minimizing risk and licensing costs in a BYOL scenario.
Windows is the most common product brought to Dedicated Hosts. What are my options for bringing development licenses to AWS? AWS customers have options for bringing Microsoft developer products to AWS for use on test, development, and non-production workloads. EC2 Bare Metal offers default tenant and dedicated host options.
The licenses must be deployed on EC2 Dedicated Hosts. You have the option to launch instances onto a specific Dedicated Host, or you can let Amazon EC2 place the instances automatically based on your licensing preferences in AWS License Manager. Controlling instance placement allows you to deploy applications to address licensing, corporate compliance, and regulatory requirements. You can run different instance sizes within the same instance family on a Dedicated Host using AWS Nitro instance family.
This allows you to maximize utilization of your Dedicated Host fleet as well as your software licenses. How do I import and use my own Windows Server license? Visit this link for more information on how to bring your own machine images into AWS. Keep in mind that when you choose to bring in your existing Windows Server licenses, you cannot utilize Windows Server AMIs that you purchase from AWS through license-included instances.
You must bring in your own licenses using your own software media. These changes are paired with Host level data, such as the Host ID and the number of sockets and physical cores installed on a Dedicated Host. AWS Config will also keep track of instance tags. We recommend that you tag your instances with a meaningful identifier if you would like a human-readable way to identify BYOL instances in the AWS Config output.
Visit this page for more information on AWS Config. Visit the Dedicated Hosts detail page for information on the number of instances available per Dedicated Host. On this page you will also find the number of sockets and cores installed on each EC2 Dedicated Host. The instance, socket, and core counts vary by the instance type configuration of the Dedicated Host.
In , Microsoft updated the licensing terms for dedicated hosts cloud service. For more details refer to the pricing section for software usage on Dedicated Hosts.
Does License Mobility work with Windows Server? You should not use your own Windows Server license on EC2 instances with default tenancy unless you have approval from Microsoft to do so. If you have negotiated custom terms with Microsoft and have this permission, please contact AWS support or reach out to your account manager. AWS manages the licensing for you; all you need to do is pay for the instances you use. Each instance comes with two remote connections for admin purposes only.
If you require more than two connections, or need those connections for purposes other than admin, you may have to bring in additional Remote Desktop Services CALs for use on AWS. However, if you need to migrate from license-included to BYOL and have applications or OS configurations that need to be migrated, we suggest that you reach out to our partners, such as CloudEndure or AppZero, who may be able to assist with these types of migrations.
Microsoft requires that customers complete and send a License Mobility verification form which can be downloaded here. There are various factors to consider when licensing passive failover for SQL Server. In all cases, you must license Windows Server. To assist you with your virtual core licensing calculations under the Microsoft Product Terms, we provide a table here that shows the number of virtual representations of hardware threads based on instance type. Using this information, you can calculate the number of SQL Server licenses that you need to bring in.
For additional information, we recommend referencing Microsoft documentation, such as the licensing guide for SQL Server see here. SQL Server Web may not be used to support line of business applications e. Using AWS Config as the data source you can track configuration changes against physical resources such as sockets and cores.
These changes are paired with Host level data, such as the Host ID and the number of sockets and physical cores installed. We recommend that you tag your instances with a meaningful identifier if you would like a human-readable way to identify BYOL instances in your AWS Config logs. SQL Server Developer Edition is eligible for use in non-production, development, and test workloads.
An unlimited number of end users can access SQL Server on a license included instance. However, Microsoft made changes to the license terms under these specific subscription programs that do not permit BYOL for subscriptions purchased or renewed after October 1, , and these new terms become effective at renewal. Microsoft Dynamics On-premises can be licensed with perpetual licenses with Software Assurance SA , or with active user subscription licenses.
Can I buy other license included Microsoft products for use on EC2? Can I bring in my own licenses for use on AWS? We have many customers that have successfully brought in and deployed licenses on Amazon EC2. Customers can choose to use shared EC2 instances and utilize License Mobility or they can purchase EC2 Dedicated Hosts and utilize physically dedicated hardware. How can I obtain additional Remote Desktop Services licenses? This Quickstart is available to help you provision these licenses for your administrators.
Under this model, you would deploy your service on AWS and rent remote desktop licenses for your end users on a monthly basis. In contrast, when System Center products are purchased individually as Client Management Licenses, and are not purchased as part of System Center Standard or System Center Datacenter suites, the licenses are intended for managing end user clients rather than server environments.
This allows them to take advantage of pricing that they have negotiated with Microsoft under their EA. Microsoft requires that customers not mix self-hosting rights and SPLA for each application. If you have a solution that is licensed under the self-hosting benefit and you wish to bring it to AWS, you can deploy this on EC2 default tenancy. In this scenario, you would still be required to purchase a Windows license-included instance.
We encourage startups to try AWS Activate , with benefits including usage credits, support, training and more. Look for the date stamp in the AMI name. You find the date stamp last 8 digits at the end of the AMI name.
