What is Microsoft SQL Server?

Microsoft SQL Server is a relational database management system (RDBMS) used across various industries for data storage, retrieval, and management.

Its good performance, comprehensive features and integration capabilities make it a preferred choice for many enterprises. However, understanding how to license SQL Server effectively is crucial to optimize costs and ensure compliance.

SQL Server Core Licensing Terms

Define core-based licenses

Core-based licensing is a model where licenses are assigned based on the number of cores per processor. Each core must be licensed, with licenses typically sold in packs of two. This model is beneficial for high-performance systems as it allows for scalability across multiple cores. You don’t have to pay for users accessing these servers (like in the SQL Server + CAL or the Windows Server core + CAL model).

Minimum core requirements

Microsoft requires a minimum of four core licenses per physical processor. This ensures that even smaller servers with fewer physical cores are adequately licensed and compliant with SQL Server’s licensing terms.

To correctly license a machine, you count the total number of (physical) cores in a server and purchase the appropriate number of core licenses required for this server.

Other key terms

  • Server + CAL (Client Access License): This licensing model requires both a server license and individual CALs for each user or device accessing the SQL Server. This can be cost-effective for smaller organizations with fewer users.
  • Editions: SQL Server is available in various editions, each designed to meet different needs. More detailed information on SQL Server editions here.

Choosing the right licensing model

Server + CAL vs Per Core Models

  • Server + CAL model: Cost-effective for a small number of users. Requires a server license and separate CALs for each user/device.
  • Per Core model: Simpler for larger deployments, especially where the number of users is high or varies.

Pros and Cons of Each Model

Server + CAL

  • Pros: Lower cost for small user bases.
  • Cons: Can become expensive with a high number of users.

Per Core

  • Pros: Predictable costs, no need to track user/device CALs.
  • Cons: Higher upfront costs, especially for servers with many cores.

SQL Server Licensing Models

Microsoft SQL Server offers two main licensing models to cater to different deployment needs. Let’s explore each model in detail and the factors influencing your choice:

1. Server + Client Access License (CAL):

This model is user or device-centric, meaning you need licenses for both the server itself and every user or device accessing it.

Server License: This grants the right to install and run SQL Server software on a single physical server. You need one server license per operating system environment (OSE) running SQL Server. Each server license allows customers to run any number of SQL Server instances in a single OSE, either physical or virtual. For VMs, specific licensing considerations exist, which we’ll discuss later.

Client Access License (CAL): This allows a user or device to connect and interact with the SQL Server instance. There are two types:

  • User CAL: Grants access to a specific user regardless of the device they use. This is ideal if you have dedicated users accessing the database.
  • Device CAL: Grants access to a specific device regardless of the user accessing it. This is suitable for scenarios where multiple users share a device to access the database.

When to choose Server + CAL?

If you can easily identify and count the users or devices accessing the database, this model offers a cost-effective approach.

This model might be preferable if you have a relatively fixed number of users or devices accessing the database.

 

2. Per Core Licensing:

This model focuses on the server’s processing power rather than individual users or devices. You license based on the number of physical cores on the server itself or the virtual cores assigned to the virtual machine running SQL Server.

Core-based costing: You purchase licenses in packs of two cores, covering all the physical cores on the server or the allocated virtual cores in a VM.

Unlimited users/devices: Unlike Server + CAL, per core licensing allows an unlimited number of users or devices to connect to the database server.

When to choose per core:

This model is ideal for scenarios with a dynamic user base, making it difficult to predict or track individual users. Per core licensing simplifies licensing for virtual environments. You can license based on the allocated virtual cores to a VM running SQL Server, offering flexibility. If user or device identification is challenging, this model eliminates the need for individual user/device CALs.

Other points to consider:

  • SQL Server Editions: Microsoft offers different editions of SQL Server, such as Standard and Enterprise, with varying features. The chosen edition may impact your licensing needs. For instance, some advanced features might be exclusive to the Enterprise edition, requiring specific licensing.
  • Virtualization Benefits: Both licensing models can leverage virtual environments. With Server + CAL, you only need one server license for either a physical server or a VM, if you license the different Operating System Environments that you use the software on. If you assign a license to a physical OSE, you can run any number of copies of the software, either physical or virtual, on that OSE. If you license a VM, this VM running SQL Server will still require its own CALs for accessing users/devices. Per core licensing offers even greater flexibility for VMs, allowing you to license based on the allocated cores per VM, so called Virtual Machine licensing.
  • Microsoft Product Terms: It’s crucial to refer to the official Microsoft Product Terms for the most up-to-date and precise licensing information. These terms can be quite detailed and may change over time, so consulting an expert can be helpful for complex scenarios.

Remember! This provides a comprehensive overview, but for specific licensing situations, it’s always best to consult with a Microsoft licensing expert who can analyze your specific deployment and recommend the most appropriate and cost-effective licensing model for your needs.

How to assign core licenses

Step-by-step process

  • Identify the deployment environment: Determine if SQL Server will run on physical hardware or within a virtualized environment.
  • Count physical cores: For physical deployments, count the total number of cores in each processor. Each core must be licensed, with a minimum of four licenses per processor.
  • Virtual environments: For virtual machines, count the number of virtual cores assigned. Each virtual core requires a license with a minimum of four licenses per VM.

SQL Server editions & features

SQL Server offers two main editions as well as several free editions.

Standard Edition:

Suitable for mid-tier applications with comprehensive data management and BI capabilities. Offers core database capabilities, OLTP, reporting, and analytics, like:

  • Data storage and retrieval
  • Backup and recovery
  • Basic security features
  • Limited reporting services (requires additional purchase)

Ideal for: Standard edition is a good choice for small to medium-sized businesses, departmental databases, and web applications.

Enterprise Edition:

The most comprehensive edition. This edition provides the full range of SQL Server functionalities, including:

  • All features of Standard edition
  • High availability features for disaster recovery and continuous uptime
  • Advanced security options for data encryption and access control
  • Built-in reporting services (SSRS) for data visualization and reporting
  • Integration Services (SSIS) for data extraction, transformation, and loading (ETL) processes
  • Analysis Services (SSAS) for complex data analysis and multidimensional modeling

Ideal for: Enterprise edition is suited for mission-critical applications, large databases, and organizations requiring advanced data management, security, and analytics capabilities.

Free editions of SQL Server:

  • Express Edition: A free, lightweight edition for small applications with limited features. Limited to 1 CPU, 1GB memory, and 10GB storage per database.
  • Developer Edition: Free for development and testing purposes but not for production use.

Down Edition Rights for SQL Server

Down Edition Rights, also known as cross-edition rights, are a valuable aspect of Microsoft SQL Server licensing. They allow you to deploy a lower-tier edition of SQL Server on a server licensed for a higher edition. Here’s a breakdown of what you need to know.

What are Down Edition Rights?

Imagine you have a license for SQL Server 2022 Enterprise edition. Down Edition Rights enable you to install and run the Standard edition of SQL Server 2022 on the same server, instead of the Enterprise edition. This can be beneficial in scenarios where you might not require all the advanced features of the higher edition, offering potential cost savings.

Important points:

  • Downgrade vs. Down Edition: Down Edition Rights are distinct from downgrade rights, which allow you to use an earlier version of the same edition. For example, a license for SQL Server 2022 Enterprise grants Down Edition Rights to Standard 2022, but not downgrade rights to Enterprise 2019.
  • Not universal: Down Edition Rights aren’t available for all licensing programs. They typically apply to Volume Licensing agreements, where organizations purchase multiple licenses. Retail and OEM licenses might have different terms.
  • Limited downgrade: You can generally only down-edition to the next lower tier. For instance, with an Enterprise license, you can use Standard, but not Express.

 Why leverage Down Edition Rights?

  • By utilizing Down Edition Rights on servers that don’t require the full functionality of the higher edition, you can optimize your licensing costs.
  • This allows you to tailor your SQL Server deployment to match specific needs on different servers within your organization.

Things to keep in mind:

Licensing Model: Down Edition Rights apply to both Server + CAL and Per Core licensing models. However, you still need to comply with the licensing requirements of the higher edition. For example, if your Server + CAL license requires CALs for all users accessing the database, even if you deploy Standard edition, you’ll still need the appropriate CALs.

Higher Editions for Lower Workloads

While Down Edition Rights allow you to leverage a lower edition on a higher-edition license, there are scenarios where you might consider using a higher edition for a lower workload. This can be beneficial for:

  • Consolidation: If you have multiple servers with varying workloads, using a single higher-edition license (like Enterprise) for all servers can offer management simplicity. You can then leverage features like Resource Governor within the higher edition to allocate resources and ensure smooth operation for the lower workloads on some servers.
  • Future-proofing: If you anticipate your workload increasing in the future, licensing a higher edition from the start can avoid the need to upgrade later. This can be cost-effective in the long run, especially if you factor in migration costs and potential downtime.
  • Feature access: Certain features might only be available in higher editions. Even if your current workload doesn’t necessitate them, having a higher edition provides access to those features if needed in the future, offering scalability and flexibility.

Important to consider:

While consolidation might simplify management, it typically comes at a higher upfront licensing cost compared to using Down Edition Rights for specific servers.

Be mindful of resource allocation when using a higher edition for lower workloads. Features like Resource Governor can help manage resource usage effectively.

SQL Server Licensing for Physical Servers & Virtual Machines

Physical Servers:

Per Core Licensing:

  1. Core-Based Licensing:
  • SQL Server is licensed based on the number of cores in the physical server.
  • You must purchase a minimum of four core licenses per physical processor.
  • This model requires you to license all the physical cores in the server.
  • SQL Server Standard and Enterprise editions both use this licensing model.

Server + CAL Licensing (for Standard Edition only):

  1. Server License:
  • You purchase a license for each physical server running SQL Server.
  1. Client Access Licenses (CALs):
  • In addition to the server license, you need to purchase CALs for each user or device accessing the SQL Server.
  • This model is suitable for environments where the number of users or devices is low.

Virtual Machines

Per Core Licensing (Virtual Cores):

  1. Virtual Core Licensing:
  • SQL Server can be licensed based on the number of virtual cores (vCores) allocated to the virtual machine (VM).
  • You must purchase a minimum of four core licenses per VM.
  • This model allows for more granular licensing, especially beneficial in environments where SQL Server instances are deployed on VMs with fewer cores than the physical server.

Enterprise Edition Benefits:

  • Unlimited Virtualization: If all physical cores on the server are licensed with SQL Server Enterprise Edition and Software Assurance (SA), you can run an unlimited number of VMs with SQL Server on that server.
  • This provides flexibility and cost efficiency in highly virtualized environments.

 Standard Edition Licensing:

  1. Per Core Licensing: Similar to Enterprise Edition, but no unlimited virtualization benefit. Each VM must be licensed based on its allocated vCores.
  2. Server + CAL: Not applicable to virtual environments as it only applies to physical servers.

 

Key considerations

Software Assurance: Provides additional benefits like License Mobility and unlimited virtualization for Enterprise Edition. It’s essential for optimizing licensing costs in virtualized environments.

High Availability and Disaster Recovery: Passive failover instances are generally allowed without additional licensing, provided the secondary server is truly passive (not serving SQL Server data outside of maintenance and failover events). There are exceptions:

  • One passive failover server is covered by the primary server’s license if no active transactions are running.
  • Licensing for Always On Availability Groups
  • Requires SQL Server Enterprise Edition and Software Assurance to use Always On Availability Groups with multiple secondary replicas.

Hybrid Environments: With Software Assurance, you can leverage the Azure Hybrid Benefit, allowing you to use SQL Server licenses in the cloud (Azure) and on-premises.

Physical Servers:

License based on physical cores (minimum of four core licenses per processor) or Server + CAL (for Standard Edition only).

Virtual Servers:

License based on virtual cores with a minimum of four core licenses per VM, or benefit from unlimited virtualization with Enterprise Edition and Software Assurance.

SQL Server Special Clauses

While there aren’t specific clauses labelled “special” within the SQL Server licensing terms, there are indeed some key features and considerations that offer flexibility and cost-optimization:

1. License Mobility within Server Farms:

This Software Assurance benefit allows you to transfer certain SQL Server licenses to different physical servers in a server farm within your organization. It provides some flexibility in managing your licensing as your server environment evolves.

Conditions: License mobility typically applies to SQL Server licenses purchased through Volume Licensing agreements. There might be specific timeframes or limitations associated with transfers, so consulting the Microsoft Product Terms for your specific agreement is crucial.

Benefits: This benefit allows you to redeploy your SQL Server licenses to new physical servers as needed, potentially reducing the need to purchase additional licenses for new hardware.

2. Software Assurance Benefits:

This is a maintenance program offered by Microsoft for Volume Licensing agreements. While not directly a licensing clause, SA offers benefits that can impact your overall licensing strategy.

Software Assurance often includes benefits like:

  • License mobility rights: Allow for greater flexibility in server deployments
  • Access to new SQL Server versions without requiring additional license purchases
  • Licensing SQL for High Availability: Provides additional licensing rights for passive failover instances to enhance system uptime
  • SQL Server Azure Hybrid Benefit: Allows you to use existing SQL Server licenses in Azure at a reduced rate
  • License Mobility through Software Assurance: Enables license deployment on-premises or in the cloud without extra costs
  • Flexible Virtualization Benefit: Allows unlimited virtual machines with SQL Server for better resource utilization

SQL Server Licensing in Cloud Environments

The rise of cloud computing presents new considerations for SQL Server licensing. Here’s a breakdown of the key aspects to understand:

Licensing in Microsoft Azure:

Microsoft Azure offers two main options for licensing SQL Server in the Azure cloud:

  • Azure Hybrid Benefit: This program allows you to leverage your existing on-premises SQL Server licenses (Server + CAL or core licenses with Software Assurance) for deploying SQL Server in Azure virtual machines (VMs). This can significantly reduce your licensing costs in the cloud.
    • Benefits: Cost savings by reusing existing licenses, promotes hybrid deployments by simplifying licensing across environments. Cost efficient for always-on systems in your cloud environment.
    • Requirements: Existing on-premises licenses with Software Assurance are typically required. Specific terms and conditions may apply, so checking the latest Microsoft Product Terms is crucial. Typically, this involves moving the solution from on-prem to the cloud as you are not allowed to use them both on-prem and in the cloud (as with Windows Server Datacenter)
  • Pay-as-you-go licensing: This model allows you to purchase SQL Server licenses directly through the Azure portal, billed based on your actual usage. It offers flexibility and avoids upfront licensing costs for new deployments.
    • Benefits: Pay-per-use model provides flexibility and cost-effectiveness for unpredictable workloads or temporary deployments.
    • Considerations: Pay-as-you-go pricing might be more expensive than using existing licenses with Azure Hybrid Benefit in the long run.

Choosing the right option:

The best option depends on your specific needs. Here’s a quick comparison to help decide:

SQL server in Azure comparison by LicenseQ

Hybrid licensing scenarios:

Combining on-premises and Azure deployments offers flexibility and cost-optimization opportunities. Here are a couple of scenarios:

  • Dev/Test environments: Utilize pay-as-you-go licensing in Azure for development and test environments, avoiding the need for dedicated on-premises licensing for these purposes. When you use Visual Studio you can reduce costs further by leveraging the Dev/Test pricing in Azure.
  • Scalable workloads: Leverage Azure Hybrid Benefit for your core production databases on-premises. During peak periods, you can scale out to Azure VMs using the same licenses, providing elasticity and cost-efficiency. Typically, the rule of thumb is if a machine is running >9 months a year, it makes sense to leverage AHB.

Optimize your SQL Server licensing costs: A strategic approach

1. Leverage Software Assurance:

Software Assurance is a maintenance program offered by Microsoft for Volume Licensing agreements.  While it’s not a free add-on, it can unlock valuable benefits that contribute to cost optimization:

  • License Mobility: SA often grants rights to transfer your SQL Server licenses to different physical servers within your organization. This flexibility allows you to redeploy licenses to new hardware as needed, potentially reducing the need for additional purchases.
  • Unlimited Virtualization: With SA, you can virtualize your SQL Server deployments without additional per-core licensing costs. This can be a significant saving if you heavily utilize virtual machines.
  • Downgrade Rights: SA may also grant downgrade rights, allowing you to use a lower edition of SQL Server on a server licensed for a higher edition. This can be beneficial if you don’t require all the features of the higher edition on specific servers.

Remember! The specific benefits and eligibility requirements for SA can vary depending on your Volume Licensing agreement. Always refer to your specific agreement terms or consult a Microsoft licensing expert for a clear understanding of what SA offers in your situation.

2. Utilize Volume Licensing programs:

For organizations with multiple SQL Server deployments, volume licensing programs like Microsoft Enterprise Agreements (EA) can offer significant cost advantages. Here’s how they can help:

  • Bulk discounts: Volume licensing programs typically provide substantial discounts on SQL Server licenses compared to individual purchases. This can translate to significant savings, especially for large organizations with numerous deployments.
  • Predictable budgeting: Volume licensing agreements often establish fixed pricing for a set period, allowing for predictable budgeting and avoiding unexpected licensing costs.
  • Additional benefits: Programs like EA might offer additional benefits beyond licensing discounts. These can include access to new software versions, training resources, and support services.

3. Analyze your needs and workloads:

Before purchasing licenses, carefully evaluate your specific requirements. Consider factors like:

  • Database size: Ensure you have the appropriate edition (Standard or Enterprise) based on your database size requirements.
  • Features required: Do you need advanced features like high availability or built-in reporting? Choose the edition that offers the functionalities you truly need.
  • Deployment environment: On-premises or cloud-based? Consider Azure Hybrid Benefit if utilizing Azure VMs with existing on-premises licenses.

4. Explore Down Edition Rights:

If you have a higher edition license (e.g., Enterprise), Down Edition Rights allow you to deploy a lower edition (e.g., Standard) on the same server. This can be a cost-saving strategy for servers that don’t require the full feature set of the higher edition.

5. Optimize Virtualization Licensing:

For virtualized environments, understand the licensing nuances for both Server + CAL and per core models. Choose the model that best suits your environment and optimize licensing based on allocated virtual cores per VM.

Also consider if you require unlimited virtualization benefits or not. Highly virtualized environments typically are most cost efficient when leveraging this benefit, though we see a lot of environments set up this way where it doesn’t make financial sense.

6. Stay up to date:

Microsoft licensing terms can evolve over time. Regularly checking the latest Microsoft Product Terms or consulting a Microsoft licensing expert ensures you’re leveraging the most recent cost-effective licensing strategies and remain compliant.
