Introduction: Executive Summary
Microsoft SQL Server (MSSQL) is a relational database management system (RDBMS) developed by Microsoft, holding a 25% share of the RDBMS market as of 2025 (DB-Engines) †. It serves organizations requiring structured data management across Windows and Linux platforms. This article evaluates its practical applications, limitations, benefits, and drawbacks for IT decision-makers assessing database options.
MSSQL performs effectively in environments integrated with Microsoft infrastructure, supporting hybrid transactional-analytical workloads, high availability needs, Azure cloud deployments, and Linux-based systems. It is less suitable for low-budget operations, simple web applications, unstructured data management, Oracle-centric setups, or small-scale devices due to cost and resource demands.
Advantages include compatibility with Microsoft tools, performance optimization, security features, and cross-platform support. Disadvantages involve high licensing fees, configuration complexity, vendor dependency, and resource and talent requirements.
Approximately 25,000 companies utilize MSSQL (6sense, 2025), reflecting its adoption in enterprise settings. This analysis provides factual insights into where it fits and where it does not, based on technical specifications and deployment outcomes.
The following sections detail specific use cases, strengths, and weaknesses to inform selection decisions, and was written in response to one of our customers requiring several SQL Server databases.
Total reading time is approximately 12 minutes, covering four content areas and a conclusion. Readers desiring more information are invited to follow the many links provided, as well as our References section. This brief, information-dense introduction also contains an Index of SQL Server Articles which we will maintain as new material is written.

Favorable Use Cases of MSSQL
MSSQL supports specific operational needs effectively due to its design and features. It is indeed Microsoft’s flagship relational database system. The following business use cases favor MSSQL as the best choice among available alternatives.
Back to Contents · Back to Top
Integration with Windows Environments
MSSQL aligns with organizations using Windows Server, Active Directory, and .NET frameworks. A retail company can manage point-of-sale data, linking it to Power BI for real-time sales reports tied to employee credentials. A financial institution running Dynamics 365 can process payroll data and generate tax documents via SQL Server Reporting Services. Over 25,000 firms deploy MSSQL in such setups (6sense, 2025) †.
Back to Contents · Back to Top
Hybrid Transactional and Analytical Workloads
MSSQL handles online transaction processing and analytical processing in one instance. An e-commerce business can process 10,000 orders per minute using in-memory tables (2014), while columnstore indexes (2012) analyze sales trends concurrently. A logistics firm can track shipments and delivery patterns without additional systems.
Back to Contents · Back to Top
High Availability Requirements
MSSQL meets demands for continuous operation through Always On Availability Groups (2012). A hospital can maintain patient records with a 10-second failover between primary and backup servers. A payment processor can synchronize transaction data across sites, supporting millions of daily operations. Banks utilize this capability (6sense, 2025).

Cloud Integration with Azure
MSSQL integrates with Azure for scalable cloud solutions. A startup can shift an on-premises database to Azure SQL, retaining T-SQL syntax and scaling capacity. A media company can use Synapse Link (2022) to connect streaming data to analytics. 50% of Fortune 500 firms use Azure SQL services (Microsoft claims 95% as of 2025) †.
Back to Contents · Back to Top
Linux-Based Deployments
MSSQL operates on Linux since 2017. A firm with Ubuntu servers can manage customer data alongside Windows-based analytics. An educational institution can store student records on SUSE with in-memory performance. Per one survey, 31% of MSSQL installations run on Linux †. We have chosen to use this version of SQL Server for our development, sandbox and testing requirements, as it fits in neatly with our own infrastructure.
MSSQL fits where Microsoft infrastructure, performance, or platform flexibility is prioritized.

Use Cases Where MSSQL Is Not Recommended
MSSQL is less effective in certain scenarios due to cost and design constraints. Below, we explore the most important cases.
Back to Contents · Back to Top
Low-Budget Operations
Licensing costs of $1,000 to $14,000 per core (2025) ‡ limit MSSQL’s feasibility for small budgets. A startup can use PostgreSQL, free and open-source, for basic database needs. MSSQL Express, capped at 10GB and four cores, lacks scalability.
Back to Contents · Back to Top
Simple Web Applications
MSSQL’s features exceed requirements for lightweight web systems like blogs. MariaDB or MySQL, with lower resource needs, suffice for content management or user data storage. MSSQL’s installation demands are disproportionate.
Back to Contents · Back to Top
Unstructured Data Management
MSSQL targets structured data, not unstructured datasets like social media posts. MongoDB, a NoSQL system, manages JSON documents and schema changes more efficiently for such applications.
Back to Contents · Back to Top
Existing Oracle Environments
MSSQL’s T-SQL is incompatible with Oracle’s PL/SQL, complicating transitions. A company using Oracle’s enterprise tools faces high migration costs and retraining, reducing MSSQL’s practicality.
Back to Contents · Back to Top
Small-Scale or Embedded Systems
MSSQL requires 1GB RAM and 6GB disk space minimum ‡, unsuitable for small devices. SQLite, at 500KB, supports IoT or mobile applications with minimal overhead.
MSSQL does not align with low-cost, lightweight, or non-relational needs.

Advantages of MSSQL
MSSQL provides technical and operational benefits in suitable contexts. In general, MSSQL is the first choice of a database for Microsoft-intensive ecosystems. Additionally, their Linux version is a good fit for shops preferring Microsoft for its user-friendliness and familiarity (mostly client-side applications) while preferring Linux on the server side for its flexibility, power, stability and uptime.
Integration with Microsoft Ecosystem
MSSQL connects with Windows Server, Active Directory, and .NET, streamlining deployment. It supports SSRS and Power BI for reporting and visualization, reducing configuration effort.
Back to Contents · Back to Top
Performance Capabilities
In-memory tables (2014) and columnstore indexes (2012) enable fast query execution. These features handle demanding workloads.
Back to Contents · Back to Top
Security Features
Transparent Data Encryption and row-level security meet NIST standards, ensuring compliance with regulations like GDPR. Configuration is managed via SQL Server Management Studio.
