Azure Database for MySQL is a fully managed relational database service built on the MySQL Community Edition database engine. It allows you to focus on application development without needing to manage infrastructure, patch operating systems, or perform backups.
Azure Database for MySQL offers two primary deployment options:
- Single Server: A managed database service for developers who need a simple, fully managed relational database.
- Flexible Server: Provides more control over database management, performance tuning, and cost optimization. It's suitable for workloads that require greater flexibility and control.
Pricing is based on several factors, including:
- Compute tier: (e.g., Basic, General Purpose, Memory Optimized)
- vCores: The number of virtual CPUs allocated.
- Storage: The amount of storage provisioned.
- Backup storage: The amount of storage reserved for backups.
- Region: Prices can vary slightly by Azure region.
You can use the Azure Pricing Calculator for detailed estimates.
Azure Database for MySQL supports MySQL Community Edition versions 5.6, 5.7, and 8.0.
For Single Server deployments, high availability is built-in using Azure's zone-redundant storage and automated failover. Flexible Server offers different high availability options, including Zone Redundant HA, which provides automatic failover to a standby replica in a different availability zone.
Yes, you can migrate your existing on-premises or cloud-hosted MySQL databases to Azure Database for MySQL. Common migration tools include:
- Azure Database Migration Service (DMS): A comprehensive service for migrating databases with minimal downtime.
- mysqldump and mysqlpump: For logical backups and restores.
- Replication: To set up continuous data synchronization during migration.
Azure Database for MySQL provides robust security features:
- SSL/TLS encryption: For data in transit.
- Azure Private Link: For secure private connectivity.
- Firewall rules: To control access to your database server.
- Azure Active Directory authentication: For centralized identity and access management.
- Encryption at rest: Using AES-256.
You can monitor your database performance using:
- Azure Monitor: Provides metrics, logs, and alerts for your database server.
- Query Performance Insight: Helps identify the longest-running queries and their resource consumption.
- Intelligent Insights: Automatically detects issues that might cause performance degradation.
Single Server: Offers a simpler, more cost-effective solution for basic workloads. It has limited configuration options and is ideal for development and testing or less demanding production environments.
Flexible Server: Provides greater control and flexibility. It supports zone-redundant HA, configurable server parameters, maintenance windows, and better cost optimization features. It's recommended for most production workloads requiring high availability and performance tuning.
You can connect to your Azure Database for MySQL using any standard MySQL client or tool. The connection string typically includes:
- Server name (e.g.,
your_server_name.mysql.database.azure.com) - Database name
- Username
- Password
Ensure your client IP address is allowed through the server's firewall rules or use Azure Private Link for secure, private connectivity.
