Azure Database for MySQL: Managed Database Service from Microsoft

Azure Database for MySQL is a fully managed relational database service built on the MySQL Community Edition engine, delivering enterprise-grade high availability, automatic backups, and intelligent performance tuning without the burden of database administration. Whether you are running a SaaS application, an e-commerce platform, or migrating legacy MySQL workloads to the cloud, Azure Database for MySQL provides the reliability and scalability that production environments demand. EPC Group has migrated hundreds of MySQL databases to Azure for clients across healthcare, finance, and retail.

Overview of Azure Database for MySQL

Azure Database for MySQL - Flexible Server is the current recommended deployment model, replacing the older Single Server option. Flexible Server delivers greater control over database configuration, same-zone and zone-redundant high availability options, and cost optimization through burstable compute tiers. The service supports MySQL versions 5.7 and 8.0, with automated patching and version upgrades.

Microsoft manages the underlying infrastructure, operating system, and MySQL engine, including patching, backups, and failover. This allows your development team to focus on application logic and query optimization rather than database administration tasks.

• Flexible Server: Zone-redundant HA, burstable compute, stop/start capability, and custom maintenance windows
• MySQL 5.7 and 8.0: Full compatibility with MySQL Community Edition including stored procedures, triggers, and views
• Built-in HA: Same-zone and zone-redundant high availability with automatic failover
• Automated backups: Point-in-time restore with up to 35 days of backup retention
• Read replicas: Up to 10 read replicas for read-heavy workloads, including cross-region replicas

Key Features

• Zone-redundant high availability: Automatic failover between availability zones with near-zero data loss
• Intelligent performance: Query performance insights, slow query log analysis, and performance recommendations
• Flexible scaling: Scale compute and storage independently with no downtime for storage scaling
• Stop/start capability: Stop the server when not in use (dev/test) and resume without losing data
• Custom maintenance windows: Schedule patching during business-appropriate windows
• Data encryption: Encryption at rest with service-managed or customer-managed keys (CMK)
• SSL/TLS enforcement: Encrypted connections with configurable minimum TLS version
• Private Link: Network isolation through Azure Private Endpoint
• Azure AD authentication: Use Azure AD identities for database access alongside MySQL native authentication
• Audit logging: Full audit log support for compliance requirements
• Data-in transit encryption: Required SSL/TLS connections for all client communications

Pricing Tiers

Azure Database for MySQL Flexible Server offers three compute tiers designed for different workload profiles. Storage is billed separately and can be scaled independently.

Storage costs range from approximately $0.115 per GB/month for general-purpose storage to $0.23 per GB/month for premium SSD. Backup storage is free up to 100% of provisioned server storage; additional backup storage is billed per GB.

Enterprise Use Cases

• SaaS applications: Multi-tenant databases with read replicas for scaling and zone-redundant HA for reliability
• E-commerce platforms: High-availability product catalogs and order management systems
• Content management: WordPress, Drupal, and custom CMS deployments with managed MySQL backends
• Healthcare applications: HIPAA-compliant patient data management with encryption and audit logging
• Legacy application modernization: Migrate on-premises MySQL databases to Azure without application code changes
• Geographically distributed reads: Cross-region read replicas for global applications requiring low-latency reads

Integration with Other Azure Services

• Azure App Service: Native connectivity for web applications with virtual network integration
• Azure Kubernetes Service: Connect containerized applications to MySQL with private endpoints
• Azure Data Factory: ETL and data movement pipelines to and from MySQL databases
• Azure Database Migration Service: Zero-downtime online migration from on-premises MySQL to Azure
• Power BI: Direct Query and Import connections for real-time business intelligence dashboards
• Azure Monitor: Database metrics, alerts, and diagnostic logging for operational visibility
• Microsoft Defender for Cloud: Advanced threat protection detecting anomalous database activities

Best Practices for Enterprise Deployments

• Enable zone-redundant HA: For production workloads, always configure zone-redundant high availability
• Use private endpoints: Never expose your database to the public internet; use Private Link for all connections
• Configure read replicas: Offload reporting and analytics queries to read replicas to reduce primary server load
• Enable audit logging: Required for HIPAA, SOC 2, and other compliance frameworks
• Use connection pooling: Implement connection pooling (ProxySQL or application-level) to avoid connection exhaustion
• Monitor slow queries: Enable slow query logging and review Query Performance Insight regularly
• Plan backup retention: Set retention to 35 days for production; configure geo-redundant backup storage for DR
• Use Azure AD authentication: Centralize identity management and eliminate shared passwords
• Right-size compute tier: Start with General Purpose and move to Business Critical only when latency requirements demand it
