To use the Server + CAL model in a virtual environment you simply purchase one server license for each virtual machine running SQL Server.

When deploying SQL Server 2014 software in virtualized environments you can choose to license either individual virtual machines or to license for maximum virtualization on the server. Virtualization always throws in a few twists and turns when it comes to licensing.

If you install any of these components on another server then an additional SQL Server license is required for each system where they they are installed. In this case you need to be aware that the different software components cannot be licensed separately. You might put Reporting Services or Analysis Services on different servers than the SQL Server Database Engine. For instance, in larger implementations it’s common to install different SQL Server components on different servers. Once you know about the basic SQL Server licensing models you need to know how this applies to the way that you might install SQL Server. I’ll cover more about virtualization and licensing in the SQL Server and Virtualization section. There is a minimum of four core licenses required per virtual machine. If you are running in a virtual environment then you need to license the number of virtual CPUs that you are using. If you are running SQL Server on a physical server then all of the cores in the server must be licensed. You don’t need to purchase CALs to access SQL Server instances that are licensed using the Core model. The Core model allows access for an unlimited number of users or devices to connect which makes it appropriate for Internet and cloud implementations. The number of core licenses needed depends on whether customers are licensing the physical server or SQL Server instances running in virtual machines. With the Core licensing model, each server running SQL Server 2014 or any of its components like Analysis Service, Reporting Services or Integration Services must be assigned some number of SQL Server 2014 core licenses. This model is appropriate for on-premise implementations where you know the number of users and devices that will connect to the server. When licensing SQL Server using the traditional Server + CAL model you need to purchase a server license for each server, and client access licenses (CALs) for each device or user that accesses SQL Server.

SQL Server Enterprise Edition: Core licensing.

SQL Server Business Edition: Server + CAL licensing.

SQL Server Standard Edition: Server + CAL or Core licensing.

The different editions of SQL Server 2014 offer the following licensing options: With the explosion of server cores in modern CPUs Microsoft followed Oracle’s lead and switched from a processor licensing model to a core licensing model. Before that you had the option of licensing on a Server + CAL basis or according to the physical processors (sockets) that were on the server. Server vs Core Licensingīeginning with SQL Server 2012 Microsoft changed the way that SQL Server was licensed and began using core licensing. While the entire ins and outs of licensing would take a small book to cover here are some of the most important things you need to know about SQL Server 2014 licensing.

And if that’s not enough there are considerations for AlwaysOn Availability Groups, virtualized SQL Server instance and even which Windows Server edition you’re running on. There are multiple different license types. Each SQL Server edition has a different licensing model and some have more than one.

Like most Microsoft products, sometimes the licensing can be more difficult to figure out than the technical aspects of the product, and SQL Server is no different.
