The primary role of an SQL server is to store and retrieve data when requested by other software applications. Part of the complexity of this database software is the sheer number of other software applications it must communicate with.
There are usually two types of organizations that require Microsoft SQL Server, one with a limited number of users, such as a private network. For this type of customer, they offer a separate license for each device that accesses the network, usually, when there is a limited number of users.
For businesses with a near-unlimited number of users such as a large organization that provides access to the public, Microsoft offers SQL Server licenses by the server and works as a catch-all license for all users as opposed to by the device. This is referred to as the core licensing model. An SQL server can be used for a variety of functions and come in all kinds of sizes depending on the workload and function.
An SQL server also processes different kinds of data including data warehousing, big data clusters, financial data, and performs data analysis. Core-based licensing is the licensing model used by Microsoft and allows license for any device accessing the SQL Server.
Under this license, each server that hosts SQL Server software on a physical server or operating system environment OSE will be granted a license for each core in the processor. An example of this could be a credit card company operating a server farm that must process thousands of transactions each minute.
Each time a device such as a point of purchase system requires access, they will have client access licenses that allow them to access the information on the server.
SQL software licensing must be included with the purchase of a server and is a separate fee. As part of the services provider license agreement, you will need at least four core licenses for each physical processor on the server core licenses are sold in packs of two , as well as having all of the components within the server appropriately licensed.
You cannot use the license by spreading it out across components in multiple servers. For example, if you try to run the SQL server reporting services on another machine, you will violate the license agreement. With this, you will have a license assigned to the operating system, the physical server, the physical cores as well as an individual license for anyone accessing the server.
For example, an app that needs to support business operations 24x7. Workloads with known lifetime and scale. For example, an app that is required for the whole year and which demand has been forecasted. The pricing level provided through Volume Licensing programs varies, based on the type of agreement and the quantity and or commitment to SQL Server.
But as a rule of thumb, bringing your own license for continuous production workloads has the following benefits:. The links to the previous images have instructions on how to do this. To avoid unnecessary costs, choose an optimal virtual machine size and consider intermittent shutdowns for non-continuous workloads.
There are new machine sizes that work well with certain types of SQL Server workloads. For example, consider the following example:. This is a point-in-time example.
For the most recent specifications, refer to the machine sizes articles and the Azure pricing page for Windows and Linux. This is one example, and there are many machine sizes with constrained vCPUs that are identified with this suffix pattern. For more information, see the blog post Announcing new Azure VM sizes for more cost-effective database work. If you are using any workloads that do not run continuously, consider shutting down the virtual machine during the inactive periods.
