This article provides details of features supported by the various editions of SQL Server 2017 on Linux. For editions and supported features of SQL Server on Windows, see Editions and supported features of SQL Server 2017.
Installation requirements vary based on your application needs. The different editions of [!INCLUDE ssNoVersion] accommodate the unique performance, runtime, and price requirements of organizations and individuals. The [!INCLUDE ssNoVersion] components that you install also depend on your specific requirements. The following sections help you understand how to make the best choice among the editions and components available in [!INCLUDE ssNoVersion].
For the latest release notes and what's new information, see the following:
For a list of SQL Server features not available on Linux, see Unsupported features and services.

You can install just the [!INCLUDE ssNoVersion] client components on a computer that is running client/server applications that connect directly to an instance of [!INCLUDE ssNoVersion]. A client components installation is also a good option if you administer an instance of [!INCLUDE ssNoVersion] on a database server, or if you plan to develop [!INCLUDE ssNoVersion] applications.
SQL Server 2017 on Linux supports the SQL Server database engine. The following table describes the features in the database engine.
| Server components | Description |
|---|---|
| [!INCLUDE ssDEnoversion] | [!INCLUDE ssDEnoversion] includes the [!INCLUDE ssDE], the core service for storing, processing, and securing data, replication, full-text search, tools for managing relational and XML data, and in database analytics integration. |
