Move Your Databases to a Fully Managed, Secure and Scalable Cloud with Microsoft Azure SQL

Azure SQL is a fully managed family of cloud databases built on the SQL Server engine you already know. It runs on the same SQL codebase from on-premises servers to the cloud and out to edge devices. Microsoft handles patching, backups and infrastructure, so your team can stay focused on building applications and delivering business value.

What Is Azure SQL?

Azure SQL is a family of cloud database services built on the SQL Server engine. Rather than a single product, it brings together four deployment options that answer different needs: fully managed Azure SQL Database for cloud-native applications, Azure SQL Managed Instance with near 100 percent SQL Server compatibility, SQL Server on Azure Virtual Machines for workloads that require operating system level control, and Azure SQL Edge for edge scenarios.

Because all of these options share the same SQL codebase, your existing SQL skills carry over unchanged. You move applications to the cloud without rewriting them, scale capacity in seconds as workloads grow, and pay only for the resources you use. With Pargesoft, a team specialized in Azure cloud solutions, you choose the right deployment model based on your business goals.

  • One Codebase from Edge to Cloud SQL Server and Azure SQL share the same engine. Your team keeps developing with the skills it already has, without learning a new technology.
  • Automated Maintenance and Updates Patching, backups, version upgrades and hardware management all run on the platform side, freeing your database administrators from routine operational work.
  • Elastic Scale and Pay As You Go The serverless tier automatically pauses idle databases, while Hyperscale scales a single database to very large sizes without friction.

Azure SQL built-in security: encryption, identity and threat protection

Protect Your Data at Every Layer with Built-in, Intelligent Security

Azure SQL treats security as part of the engine rather than a layer added afterwards. Data is encrypted both at rest (Transparent Data Encryption) and in transit, and Always Encrypted keeps your most sensitive fields hidden even from database administrators. Microsoft Entra ID based authentication, role based access control and dynamic data masking limit permissions according to the principle of least privilege. Microsoft Defender for SQL monitors potential threats in real time and surfaces risks early through vulnerability assessments. As a result, you benefit from one of the broadest compliance coverages in the industry while reducing your audit burden.

Multi-Layered Encryption and Identity

TDE, Always Encrypted and Microsoft Entra ID authentication work together. Your data is protected end to end while access permissions are managed centrally and on a time-limited basis.

Continuous Monitoring with Defender for SQL

Intelligent threat protection and vulnerability assessment detect misconfigurations and suspicious activity in real time, generating proactive alerts.

Azure SQL cost management: Azure Hybrid Benefit, reserved capacity and serverless tier

Scale at the Lowest Total Cost of Ownership

Cost control in the cloud starts with choosing the right pricing model. The Azure Hybrid Benefit lets you bring your existing SQL Server licenses to the cloud and save up to 85 percent compared with pay-as-you-go pricing. Reserved capacity adds further discounts for predictable workloads, and you can also take advantage of reduced rates for your development and test environments.

The serverless tier automatically pauses idle databases and charges only for the seconds of active compute. Elastic pools allow multiple databases to share the same resource budget. By monitoring all of your databases, virtual machines and instances from a single portal, you quickly identify idle resources and make your spending predictable.

The Right Azure SQL Option for Every Workload

Azure SQL is not a single service but a family that works together. Whether you migrate your existing SQL Server environment as it is or build a cloud-native application from scratch, you select the deployment model that best fits your needs within the same ecosystem.

1

Azure SQL Database

A fully managed service for cloud-native applications. With serverless compute, the Hyperscale architecture and elastic pools, you strike the right balance between scale and cost at the lowest operational overhead.

2

Azure SQL Managed Instance

Near 100 percent SQL Server compatibility. Instance-level features such as SQL Agent, cross-database queries and CLR let you migrate existing applications to the cloud with minimal changes.

3

SQL Server on Virtual Machines

Full operating system level control and 100 percent compatibility. For workloads that need third-party agents or custom configurations, you perform a direct lift-and-shift.

4

Azure SQL Edge and Azure Arc

Extend database capabilities to IoT edge devices, and run your on-premises and multicloud environments from a single management plane with Azure Arc.

Turn Your Data into an AI-Ready Ecosystem

You no longer need complex technology stacks for generative AI applications. Azure SQL runs AI capabilities right at the heart of your data, in the T-SQL layer, turning your database into an intelligent inference engine.

While simplifying your architecture, you equip your data with the following capabilities without compromising your existing enterprise security standards (Microsoft Entra ID and Purview):

Native Vector Data Management

Manage high-dimensional embeddings directly inside SQL with the new VECTOR data type and DiskANN indexing. Run semantic search without the cost of an extra database or the risk of copying data around.

Grounded RAG Workflows

Call Azure OpenAI models directly in the query layer through AI_GENERATE_EMBEDDINGS integration. With retrieval-augmented generation (RAG), you ground AI responses in your real enterprise data and reduce hallucinations.

Data Democratization with Copilot

With Copilot support in SSMS and the Azure portal, turn natural language requests into accurate T-SQL code in seconds. Speed up development while making data accessible to every team.

Frequently Asked Questions (FAQ)

What is the difference between Azure SQL and SQL Server?
Both use the same SQL Server engine; the key difference is the management model. SQL Server is a product that you install and manage yourself. Azure SQL, on the other hand, is a fully managed cloud service that Microsoft runs on your behalf: patching, backups, high availability and hardware management are handled on the platform side. Because query performance is similar, your existing SQL skills apply to both; you simply shed the operational burden and focus directly on your application.
Which Azure SQL deployment option should I choose?
If you are building a cloud-native application from scratch, Azure SQL Database is a good fit, offering the lowest operational overhead with its serverless and Hyperscale options. If you want to migrate an existing SQL Server environment quickly and with minimal changes, Azure SQL Managed Instance is ideal thanks to its near-full compatibility. If you need operating system level control or third-party components, you can perform a lift-and-shift with SQL Server on Azure Virtual Machines. For hybrid scenarios, Azure Arc and Azure SQL Edge come into play. The right choice depends on your workload, compliance requirements and cost balance.
Can I bring my existing SQL Server licenses to Azure?
Yes. With the Azure Hybrid Benefit, you can bring SQL Server licenses with active Software Assurance to Azure SQL and save up to 85 percent compared with pay-as-you-go pricing. When you combine this benefit with reserved capacity pricing, you lower costs even further for predictable workloads. This way you protect your existing investments while enjoying the flexibility that comes with moving to the cloud.
How does Azure SQL protect my data?
Azure SQL takes a multi-layered, built-in approach to security. Data is encrypted both at rest (Transparent Data Encryption) and in transit; Always Encrypted keeps your most sensitive fields hidden even from database administrators. Authentication runs through Microsoft Entra ID, and permissions are granted at the lowest level through role based access control. Microsoft Defender for SQL monitors threats in real time, while vulnerability assessment surfaces risks early. All of this is backed by one of the broadest sets of compliance certifications in the industry.
