Microsoft SQL Server 2017 Standard

Microsoft SQL Server 2017 Standard: The Database That Broke Platform Barriers

For over two decades, Microsoft SQL Server was synonymous with Windows infrastructure. SQL Server 2017 Standard changed that forever. This landmark release is the first to deliver a fully-featured, Microsoft-supported SQL Server engine running natively on Linux, opening the door to heterogeneous data centres, containerised deployments, and significant licensing flexibility. Whether you are a database administrator managing mixed-OS environments, a developer building modern applications on your preferred Linux distribution, or a growing business needing a robust, secure, and intelligent relational database management system, SQL Server 2017 Standard provides the mission-critical foundation you require.

This is a genuine, perpetual Microsoft Retail license, meaning you own the right to use this software indefinitely for the version purchased. It is not a time-limited subscription. The key advantage is cross-platform consistency: the same enterprise-grade engine, the same T-SQL surface area, and the same security model now run on Windows Server, Windows 10, Windows 11, Ubuntu, Red Hat Enterprise Linux, and SUSE Linux Enterprise Server. You gain architectural freedom without sacrificing performance or supportability, backed by Microsoft's extended support lifecycle through October 2027.

Key features and benefits

• Native Linux deployment with full feature parity: Run SQL Server on Ubuntu, RHEL, or SLES without Windows licensing overhead. This allows you to standardise your database platform across your entire infrastructure, reducing costs and complexity by using a single engine for both Windows and Linux workloads.
• Adaptive Query Processing for automatic performance tuning: Unlike traditional query optimisers that rely on fixed, compile-time estimates, SQL Server 2017 dynamically adjusts execution strategies at runtime. This means your complex queries automatically improve over time without manual intervention, reducing troubleshooting and maintaining consistent performance as data grows.
• Graph database capabilities built into the engine: Model highly interconnected data, such as social networks, recommendation engines, or fraud detection patterns, using native NODE and EDGE tables. The new MATCH syntax simplifies queries that would otherwise require dozens of lines of complex recursive CTEs, making your code more readable and maintainable.
• In-database advanced analytics with R and Python: Bring your predictive models directly to your data by executing R and Python scripts inside the database via Machine Learning Services. This eliminates the security risk and latency of moving sensitive production data to external analytical workstations, enabling real-time intelligent applications.
• Automatic database tuning that learns your workload: SQL Server can now continuously monitor query performance, automatically creating and verifying covering indexes, and forcing the last known good execution plan when a regression is detected. This acts like a virtual DBA, resolving common performance issues without human intervention, even during off-hours.
• Resumable online index rebuilds for large-scale maintenance: Pause and resume index maintenance operations across multiple maintenance windows. You no longer need to restart a multi-hour index rebuild from scratch if a window expires, giving you complete control over resource-intensive tasks on very large databases.
• Intelligent query processing with memory grant feedback: The engine automatically corrects oversized or undersized memory allocations for repeated queries. This prevents one poorly estimated query from hogging resources and starving others, leading to more stable and predictable overall server performance.
• Always Encrypted for data protection at rest and in motion: Protect sensitive data, such as credit card numbers or health records, with encryption that never reveals the decryption keys to the database engine. This helps achieve compliance with regulations like GDPR by ensuring even database administrators with full system access cannot read personally identifiable information.
• Robust scalability for mid-tier workloads: The Standard edition supports up to 24 processor cores and a generous 128 GB of memory for the buffer pool, providing ample headroom for demanding departmental applications, web databases, and line-of-business systems without the cost of the Enterprise edition.

What's included with your purchase

When you purchase Microsoft SQL Server 2017 Standard from Lizensa, you receive a complete, legally compliant licensing package. Your order confirmation email, delivered within seconds of a successful payment, contains your unique, genuine Microsoft Retail license key. This is a perpetual license, granting you the right to use the software indefinitely for the 2017 version; it does not expire and is not a monthly or annual subscription.

Alongside the key, you receive a direct link to download the official, unmodified Microsoft installation media, ensuring you get a clean, untampered binary. A detailed, step-by-step activation guide is included to walk you through the installation and online activation process. You will also receive a full EU-compliant VAT invoice, suitable for business accounting and tax purposes. This license is a Retail (Full Packaged Product equivalent) license, which provides the most flexible transfer rights compared to OEM versions, allowing you to move the license to a new server in the event of hardware failure or an upgrade.

Licensing explained: what you need to know

Understanding SQL Server licensing is crucial for compliance and budget planning. SQL Server 2017 Standard is licensed under the Server + Client Access License (CAL) model. This means you must purchase one server license for each operating system environment running SQL Server, and every user or device that directly or indirectly accesses the SQL Server must have a corresponding SQL Server CAL. User CALs license a specific person to access the server from any device, while Device CALs license a specific device, such as a shared workstation or kiosk, to be used by multiple users. You must choose either User or Device CALs based on your access patterns.

For virtualised environments, the Standard edition grants you the right to run one instance in a physical operating system environment and one instance in a virtual machine, provided the physical server is fully licensed. If you need to run multiple virtual machines on the same host, you can purchase additional server licenses and stack them. The key distinction from the Enterprise edition is scale: Standard is capped at the lesser of 24 cores or 4 sockets and 128 GB of memory, whereas Enterprise supports the operating system's maximum. Standard also lacks advanced high-availability features like Always On Availability Groups with multiple readable secondaries, making it ideal for scenarios where the core database engine, reporting, and analytics capabilities are needed without the extreme scale demands of a full data centre consolidation.

System requirements / compatibility

Before installation, verify that your environment meets the following requirements to ensure a smooth deployment. SQL Server 2017 Standard is a 64-bit application that requires a minimum processor speed of 1.4 GHz with at least 2 cores. Microsoft recommends a minimum of 4 GB of RAM for the Standard edition, with 16 GB or more strongly advised for production workloads to ensure adequate query performance and caching. A minimum of 6 GB of free disk storage is required for the core database engine and system databases.

This edition introduces official support for Linux, with validated distributions including Ubuntu 16.04 and 18.04, Red Hat Enterprise Linux (RHEL) 7 and 8, and SUSE Linux Enterprise Server (SLES) 12 and 15. On the Windows platform, supported operating systems include Windows Server 2012 R2 and later, as well as Windows 10 and Windows 11. The .NET Framework 4.6.1 is a prerequisite on Windows. Internet access is required for the product activation process. The software is available in multiple languages, including English, German, French, Spanish, Italian, Dutch, Polish, Portuguese, and Japanese. macOS is not supported as a host operating system.
