Among them, Microsoft Azure stands out as an efficient and flexible platform offering a wide range of products and services. This post will concentrate on various ways you can deploy database offerings on selected platforms, with a focus on Microsoft Azure, particularly for those preparing for exam DP-300 Administering Microsoft Azure SQL Solutions.
1. Understanding the Database Deployment
Before starting with the deployment process, it’s crucial to fully comprehend what it entails. Deployment in database terminology refers to creating a running instance of a database from a defined database model or schema.
In our context of DP-300 exam, the candidate needs to demonstrate proficiency in deploying databases in various Azure services, analyzing the resources and working with deployment templates.
2. Database Deployment on Microsoft Azure SQL
Azure SQL is a comprehensive family of managed, secure, and intelligent SQL server-based database services that helps to optimize performance and simplify your database operations. Azure provides several platform services for SQL Database deployment including Azure SQL Database, Azure SQL Managed Instance, and SQL Server on Azure Virtual Machines.
Azure SQL Database
Azure SQL Database is a fully-managed and intelligent relational cloud database service built for developers. It automates updates, patching, backups, and monitoring, saving you time and effort on database management tasks.
To deploy Azure SQL Database, follow the steps below:
- Go to the Azure portal and then select ‘Create a resource’.
- In the ‘New’ window, select ‘Databases’ and then select ‘SQL Database’.
- In the ‘SQL Database’ window, add the required details for the new SQL database and then select ‘Review + create’.
- Check the details, and once satisfactory, select ‘Create’ to start the deployment process.
Azure will take some time to deploy your SQL database and once done, it will be visible under ‘SQL databases’ in the Azure portal.
Azure SQL Managed Instance
Azure SQL Managed Instance is a fully managed SQL Server Database engine instance that’s hosted in Azure and placed in your network. This deployment model makes it perfect for a large scale migration of on-premises SQL Server to Azure as you get to manage your databases without having to maintain your SQL Server instances.
Here are the steps to deploy it:
- Go to the Azure portal then select ‘Create a resource’.
- In the ‘New’ window, select ‘Databases’ and then select ‘SQL Managed Instance’.
- In the ‘SQL Managed Instance’ window, add the required details for the new SQL Managed Instance and then select ‘Review + create’.
- Check the details, and once everything is as per requirement, select ‘Create’ to start the deployment process.
SQL Server on Azure Virtual Machines
SQL Server on Azure virtual machines allows you to use full versions of SQL Server in the Cloud without having to manage any on-premises hardware. It provides automated updates, automated backups, high availability, and more.
To deploy a SQL Server on Azure VM, you can simply choose a SQL Server image from the Azure portal and the Azure will create a VM with that image.
3. Azure Database Deployment Using Azure Resource Manager Templates
Azure Resource Manager (ARM) Templates provide a declarative way to define deployment. An ARM template is a JSON file that defines the infrastructure and configuration for your project which can use to deploy and repeatedly deploy your application.
Here’s a simple ARM template for deploying an Azure SQL database.
{
“$schema”: “https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#”,
“contentVersion”: “1.0.0.0”,
“parameters”: {
“location”: {
“type”: “string”
},
“sqlServerName”: {
“type”: “string”
},
“sqlDatabaseName”: {
“type”: “string”
},
“adminUsername”: {
“type”: “string”
},
“adminPassword”: {
“type”: “securestring”
}
},
…
“resources”: [
…
],
…
}
Conclusion
Azure’s database services are designed to provide developers and IT professionals with a variety of deployment options, higher performance, and ease of database management. Whichever platform you choose for your database solution, Azure offers robust, flexible and cost-effective options. As you prepare for the DP-300 exam, understanding these options will certainly be valuable.
