Introduction to Azure Database for MariaDB
Azure Database for MariaDB is a fully managed relational database service that enables you to focus on application development rather than on infrastructure management. It's built on the MariaDB Community Edition open-source relational database engine.
Key features include:
- Managed Service: High availability, automated backups, patching, and security are handled by Azure.
- Scalability: Scale compute and storage independently and on-demand.
- Performance: Choose from different pricing tiers to match your performance needs.
- Security: Robust security features including network isolation, encryption at rest and in transit, and Azure Active Directory integration.
- Compatibility: Fully compatible with the MariaDB Community Edition.
Core Components
Understanding the core components of Azure Database for MariaDB is crucial for effective management and optimization:
- Server: The primary resource representing your MariaDB instance.
- Database: Contains your tables, views, stored procedures, and other database objects.
- Firewall Rules: Control access to your server from specific IP addresses.
- Connection Strings: Provide the necessary information for your applications to connect to the database.
Use Cases
Azure Database for MariaDB is suitable for a wide range of applications, including:
- Web applications
- Business intelligence applications
- Content management systems
- E-commerce platforms
Quickstart: Create an Azure Database for MariaDB Server
Follow these steps to quickly deploy a new Azure Database for MariaDB server.
Prerequisites
- An Azure account. If you don't have one, create a free account.
- Azure CLI installed or use Azure Cloud Shell.
Steps
- Sign in to Azure:
az login
- Create a resource group:
az group create --name myResourceGroup --location eastus
- Create a MariaDB server:
az mariadb server create --resource-group myResourceGroup --name mydemoserver --location eastus --admin-user myadmin --admin-password --sku-name B_Gen5_1 --tier Basic --workload GeneralPurpose --storage-size 5120
Replace <YourPassword> with a strong password.
- Configure firewall rules:
az mariadb server firewall-rule create --resource-group myResourceGroup --server-name mydemoserver --name AllowAzureServices --start-ip-address 0.0.0.0 --end-ip-address 0.0.0.0
This rule allows connections from Azure services.
- Connect to the server:
Use your preferred MariaDB client (e.g., mysql command-line client, MySQL Workbench) with the connection details:
- Server name:
mydemoserver.mariadb.database.azure.com
- User name:
myadmin
- Password:
<YourPassword>
