SQL Server License for 2022 Models

SQL Server licensing models for 2022 offer flexibility to suit various organizational needs, from small businesses to large-scale enterprises. Understanding these models ensures compliance and cost-effectiveness while maximizing the value of your SQL Server deployments.

Licensing Per Core

Under the SQL Server Core License model, a specific number of core licenses must be assigned to each server running SQL Server or its components, such as Reporting Services or Integration Services. This model provides a precise and consistent measure of computing power, whether you’re using on-premises physical servers, virtual servers, or cloud environments.

• Direct Licensing to Server Cores: Core licenses are assigned based on a server’s total number of physical cores. Licenses are purchased in pairs.
• Unlimited User Access: This model eliminates the need for Client Access Licenses (CALs), allowing unrestricted access for both internal and external users.
• Implementation Strategy: Calculate each server’s total physical core count and assign licenses accordingly. This is particularly suited for high-capacity workloads.
• Ideal for Large-Scale Workloads: Core-based licensing aligns well with SQL Server Enterprise Edition and supports extensive internet or extranet workloads.
• Cost Efficiency: This model can reduce overall licensing costs, especially for organizations using SQL Server Standard Edition, where the Server + CAL model might be less economical.

Licensing on Server + CAL

The Server + CAL model involves purchasing a server license and Client Access Licenses (CALs) for each user or device accessing SQL Server. This model is typically better suited for smaller organizations with a predictable and manageable number of users or devices.

• Server and CAL Requirements: Each server running SQL Server requires a single server license, and separate CALs are required for each user (User CAL) or device (Device CAL).
• Suitability: This solution is best for small—to medium-sized organizations, such as local non-profits, with a clear and stable number of users and devices.
• Separate CAL Purchases: User and Device CALs must be purchased separately. They are not interchangeable and must be assigned based on specific access needs.
• Cost-Effective for Smaller Deployments: The Server + CAL model provides a cost-effective alternative to per-core licensing for organizations with limited users or devices.

Per Core Model Advantages

The per-core model is an effective licensing option for larger, more complex workloads.

• Precise Licensing Metrics: Provides a direct correlation between computing resources and licensing requirements.
• Unlimited User Access: Supports high-traffic environments without requiring additional CALs, which is ideal for external-facing applications.
• Scalability and Flexibility: Easily scale resources up or down without adjusting CALs.
• Enterprise Use Case: Designed for SQL Server Enterprise Edition deployments with significant processing demands.

SQL Server CAL License

The Server + CAL model is often the most practical and economical solution for smaller organizations, such as local non-profits.

• Server Licensing: Each server running SQL Server requires a single server license, allowing multiple SQL Server instances within the same Operating System Environment (OSE).
• CAL Requirements: Each user or device accessing SQL Server must have a corresponding CAL.
  • User CALs: Assigned to individuals, allowing them to access SQL Server from multiple devices.
  • Device CALs: Assigned to devices, enabling multiple users to access SQL Server from a single device.
• Separate CAL Purchases: Internal and external user CALs must be purchased separately to ensure compliance.
• Cost-Effectiveness: The Server + CAL model is advantageous for smaller deployments with limited users or devices. Compared to the per-core model, it reduces overall licensing costs.

Licensing SQL Server 2022 in Virtualized Environments

SQL Server is often used in virtualized environments, which let you run multiple instances of SQL Server concurrently in different virtual operating system environments (OSEs) or virtual machines (VMs).

Microsoft offers virtualization rights, options, and benefits to give you flexibility when deploying SQL Server in virtual environments.

Licensing Individual VMs

If you’re running an SQL Server instance on a virtual machine (VM) and it’s not using all the computing power of the physical server it’s on, you can save money by licensing individual VMs.

There are two ways to do this: the Per Core and Server+CAL models.

Per Core Model

• With the Per Core model, you need to buy a core subscription license or license with Software Assurance for each virtual core (v-core) or virtual processor/CPU/thread supporting the VM running SQL Server.
  • Each v-core corresponds to a hardware thread, with a minimum of four licenses per VM.
  • You’ll need additional licenses if a single hardware thread supports multiple v-cores or multiple hardware threads support a single v-core.
  • Standard Edition customers can only license individual VMs using the Per Core model.
  • With a license with Software Assurance, you can move the licenses to another server within the same Server Farm.

Server + CAL Model

• With the Server+CAL model, you must buy one server license for each VM running SQL Server, regardless of the number of virtual processors.
  • For example, you’d need six server licenses to run Standard Edition on six VMs with four v-cores each.
  • Each user or device accessing SQL Server on the VM needs a CAL, too.
  • You don’t need a subscription license or license with Software Assurance to use SQL Server in a VM with the Server+CAL model. However, with a subscription license or license with Software Assurance, you can move the licenses to another server in the same Server Farm.

Licensing SQL Server 2022 for Maximum Virtualization

• If you have SQL Server Enterprise Edition and you’ve licensed all the physical cores on your server, you can run an unlimited number of instances of the software on as many VMs as you want, as long as you have a core license for each VM.
  • For example, if you have a four-processor server with four cores per processor and 16 core licenses, you can run SQL Server on up to 16 VMs.
  • To run it on more VMs, you must obtain and assign more core licenses to the server.
• With a SQL Server Enterprise subscription license or license with Software Assurance, you can run as many instances of the software as you want in any number of physical or virtual environments.
  • This is a good option if you have a private cloud with many VMs, are using hyper-threading, or need to dynamically provision and de-provision VM resources.
  • Ensure you keep your subscription licenses or Software Assurance coverage up to date!

MS SQL License Server 2022 in Containers

SQL Server can be used on Linux and Docker platforms, which means you can run it in containers using Docker.

A container or virtual machine is considered an operating system environment (OSE), so containers and virtual machines are treated the same from a licensing perspective.

Licensing Individual Containers

• If you use the per-core licensing model and want to run SQL Server in containers, you must purchase a core license for each virtual core (v-core) or virtual processor/CPU/thread supporting the container.
  • There’s a minimum requirement of four licenses per container.
  • A v-core corresponds to a hardware thread.
• If you have multiple containers and need to move them around to reallocate resources, Microsoft offers the Flexible Virtualization Benefit, which provides flexible reassignment rules.
• If you’re using the Server+CAL model, you must buy one server license for each container running SQL Server, regardless of the number of virtual processors.
  • For example, you’ll need six server licenses to run Standard Edition on six containers with four v-cores each.
  • Don’t forget that each user or device accessing SQL Server on the container will also need a CAL.

Licensing Containers for Maximum Density

• If you have SQL Server Enterprise Edition and have licensed all the physical cores on your server, you can run as many containers as you have core licenses.
  • For instance, if you have a four-processor server with four cores per processor and 16 core licenses, you can run SQL Server on up to 16 containers.
  • If you want to run it on more containers, you just have to get and assign more core licenses to the server.
• With Software Assurance coverage or a subscription license on all your Enterprise Edition core licenses, you can run unlimited containers on the server.
  • This is a good option if you have a private cloud with many containers, are using hyper-threading, or need to provision and de-provision container resources dynamically.
  • Just make sure you keep your Software Assurance coverage up to date!
• Suppose you have SQL Server Standard or Enterprise Edition and Software Assurance coverage or subscription licenses. In that case, you can run any number of containers in a virtual operating system environment (virtual OSE) as long as you’ve licensed all the virtual cores in that OSE.
  • For example, if you have a 16 vCore OSE (including hyperthreaded cores), you can run SQL Server on any number of containers in that OSE, regardless of the number of virtual cores per container.
