What is Azure SQL?
Azure SQL is the family of managed SQL Server database services in Azure. It includes Azure SQL Database (fully managed single/pooled databases), Azure SQL Managed Instance (near-complete SQL Server compatibility), and SQL Server on Azure VMs (full control).
All variants offer automatic patching, integrated backups, high availability, and scalability without dedicated database management.
Core Features
- Automatic patching without planned downtime
- Point-in-time restore up to 35 days back
- Geo-replication for disaster recovery
- Intelligent performance tuning with Query Store
- Advanced Threat Protection and data encryption
- Serverless compute option for variable workloads
Typical Use Cases
SaaS applications: Multi-tenant databases with elastic pools for efficient resource utilization and easy scaling.
Enterprise modernization: Migration from on-premises SQL Server to Managed Instance with minimal application changes.
Development and test: Serverless tier for development environments that only consume compute resources when needed.
Benefits
- No DBA overhead for patching and backups
- 99.99% SLA for Business Critical tier
- Seamless integration with .NET and Microsoft development tools
- Hybrid scenarios with SQL Server Data Sync
Frequently Asked Questions
What is the difference between SQL Database and Managed Instance?
SQL Database is optimized for cloud-native applications and offers elastic pools. Managed Instance provides near 100% compatibility with on-premises SQL Server, including SQL Agent, cross-database queries, and CLR.
How does pricing work?
Azure SQL offers DTU-based (simpler) and vCore-based (more flexible) models. Serverless pauses automatically and saves costs. Reserved Capacity offers up to 33% discount with 1-3 year commitment.
Can I migrate existing SQL Server databases?
Yes, Azure Database Migration Service enables online migrations with minimal downtime. For Managed Instance, almost all SQL Server features are supported.
How secure is the data?
Data is encrypted at rest and in transit. Transparent Data Encryption (TDE) is enabled by default. Advanced Threat Protection detects SQL injection and anomalous behavior.
