# Editions and supported features of SQL Server 2019 on Linux

[!INCLUDE [SQL Server - Linux](../includes/applies-to-version/sql-linux.md)]

This article provides details of features supported by the various editions of [!INCLUDE [sssql19](../includes/sssql19-md.md)] on Linux.

For editions and supported features of [!INCLUDE [ssnoversion-md](../includes/ssnoversion-md.md)] on Windows, see [Editions and supported features of SQL Server 2019](../sql-server/editions-and-components-of-sql-server-2019.md). For more information on what's new in [!INCLUDE [sssql19](../includes/sssql19-md.md)] on Windows, see [What's new in SQL Server 2019](../sql-server/what-s-new-in-sql-server-2019.md).

Installation requirements vary based on your application needs. The different editions of [!INCLUDE [ssnoversion-md](../includes/ssnoversion-md.md)] accommodate the unique performance, runtime, and price requirements of organizations and individuals. The [!INCLUDE [ssnoversion-md](../includes/ssnoversion-md.md)] 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-md](../includes/ssnoversion-md.md)].

For the latest release notes and what's new information, see [Release notes for SQL Server 2019 on Linux](sql-server-linux-release-notes-2019.md).

For a list of [!INCLUDE [ssnoversion-md](../includes/ssnoversion-md.md)] features not available on Linux, see [Unsupported features and services](#unsupported-features-and-services).

## Try SQL Server

- [Download SQL Server 2019](https://www.microsoft.com/sql-server/sql-server-2019)

## SQL Server editions

[!INCLUDE [sql-server-editions](../includes/paragraph-content/sql-server-editions-1.md)]

## Use SQL Server with client/server applications

You can install just the [!INCLUDE [ssnoversion-md](../includes/ssnoversion-md.md)] client components on a computer that is running client/server applications that connect directly to an instance of [!INCLUDE [ssnoversion-md](../includes/ssnoversion-md.md)]. A client components installation is also a good option if you administer an instance of [!INCLUDE [ssnoversion-md](../includes/ssnoversion-md.md)] on a database server, or if you plan to develop [!INCLUDE [ssnoversion-md](../includes/ssnoversion-md.md)] applications.

## SQL Server components

[!INCLUDE [sssql19](../includes/sssql19-md.md)] on Linux supports the [!INCLUDE [ssDEnoversion](../includes/ssdenoversion-md.md)]. The following table describes the features in the [!INCLUDE [ssDE](../includes/ssde-md.md)].

| Server components | Description |
| --- | --- |
| [!INCLUDE [ssDEnoversion](../includes/ssdenoversion-md.md)] | [!INCLUDE [ssDEnoversion](../includes/ssdenoversion-md.md)] includes the [!INCLUDE [ssDE](../includes/ssde-md.md)], 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. |

**Developer, Enterprise Core, and Evaluation editions**  
For features supported by Developer, Enterprise Core, and Evaluation editions, see features listed for the SQL Server Enterprise edition in the following tables.

The Developer edition continues to support only one client for [SQL Server Distributed Replay](../tools/distributed-replay/sql-server-distributed-replay.md).
