What is Microsoft SQL Server?

Microsoft SQL Server is a versatile and scalable Relational Database Management System (RDBMS) used in on-premises environments. It provides several features for efficient data storage, retrieval, and management.    

SQL Server supports various data types and enables complex queries and advanced data analysis. It has robust security measures and uses the following features to ensure data protection:   

a) Authentication: SQL Server authenticates the identity of the users accessing the database, ensuring secure and authorised access to the data.   

b) Authorisation: It implements authorisation controls to determine the access and privileges granted to individual users, safeguarding data integrity and confidentiality.   

c) Data encryption: It uses encryption techniques to protect sensitive information, adding an extra layer of security to prevent unauthorised data access and maintain confidentiality.



 

What is Azure SQL?  

Azure SQL is a cloud-based database service offered by Microsoft, delivering scalable and reliable business solutions. It offers companies a secure, cost-effective cloud-based database solution with seamless integration capabilities and simplified management. Some of its key features include:   

a) Scalability: Azure SQL allows effortless scaling of databases based on demand, ensuring optimal performance and cost efficiency.   

b) High Availability: Automated backups, geo-replication, and automatic failover increase availability and data durability.   

c) Security: Advanced threat detection, data masking, and built-in security measures protect sensitive information.   

d) Integration: Seamless integration with Azure services like Data Factory, Logic Apps, and Analysis Services enables powerful data workflows and advanced analytics.   

e) Cost-effective: No upfront hardware investment, flexible pricing options, and pay-as-you-go models make Azure SQL a cost-effective choice.   

f) Ease of Management: Streamlined development and management through integration with tools like Visual Studio and SQL Server Management Studio.

Key Differences Between Microsoft SQL Server vs Azure 

When choosing the perfect database solution for your organisation, understanding the key differences between Microsoft SQL Server and Azure is crucial. Both options offer powerful capabilities but have distinct features that can influence your decision. Let's dive into the key differences and find the ideal database solution for your needs.

a) Deployment: Microsoft SQL Server is an on-premises database solution, whereas Azure SQL is a cloud-based service provided by Microsoft as part of the Azure platform.   

b) Scalability: Azure SQL offers seamless scalability, allowing businesses to scale databases up or down based on demand. Microsoft SQL Server requires manual scaling and hardware upgrades.   

c) Management: Azure SQL database provides a fully managed solution, reducing administrative tasks. Microsoft SQL Server requires more hands-on management and maintenance.   

d) Availability: Azure SQL offers built-in high availability and automatic backups, ensuring data availability. Microsoft SQL Server requires manual configuration for high availability.   

e) Security: Both solutions offer robust security features, including authentication, authorisation, and data encryption. Azure SQL provides additional built-in security measures specific to the Azure platform.   

f) Common Language Runtime (CLR): Microsoft SQL Server supports CLR integration, allowing developers to write stored procedures and functions using .NET languages. SQL Server on Azure VM (Virtual Machine) does not support CLR integration.   

g) Integration: Azure SQL integrates seamlessly with other Azure services, enabling powerful data workflows and analytics. Microsoft SQL Server integrates well with Microsoft technologies like .NET and Visual Studio.   

h) Cost: Azure SQL eliminates upfront hardware costs and offers flexible pricing models. Microsoft SQL Server requires hardware investments and has licensing costs.   

i) Data types: Microsoft SQL Server and Azure SQL support many data types, allowing flexibility in storing and manipulating different data types.   

j) Backup: Azure SQL provides automated backup functionality, flexible retention policies, and point-in-time restore capabilities. Microsoft SQL Server requires manual backup configuration and maintenance.   

k) Size: Azure SQL databases have size limitations based on the selected pricing tier, while Microsoft SQL Server's size depends on hardware limitations and storage capacity.
