Concepts
Deploying hybrid solutions with SQL Server involves combining on-premises SQL Server instances with Azure SQL. This enables organizations to leverage the benefits of both environments and optimize their workload performance, scalability, and cost-efficiency. In this article, we will explore various techniques to deploy hybrid SQL Server solutions, focusing on the functionalities provided by the Administering Microsoft Azure SQL Solutions exam.
Azure Hybrid Benefit
One of the key advantages of deploying a hybrid solution is the Azure Hybrid Benefit. This benefit allows organizations to bring their existing SQL Server licenses to Azure and reduce costs. By utilizing the Azure Hybrid Benefit, organizations can save up to 55% on Azure SQL Database Managed Instance cost. To take advantage of this benefit, you need active Software Assurance on your SQL Server licenses. This benefit can be applied to individual databases or a managed instance.
To deploy a hybrid SQL Server solution using Azure Hybrid Benefit, you can follow these steps:
- Install SQL Server on-premises or use an existing SQL Server instance.
- Determine the licensing model appropriate for your deployment – Core-based or Server/CAL.
- Sign in to the Azure portal and navigate to the SQL Server page.
- Create a new Azure SQL Database Managed Instance.
- During the creation process, select the appropriate licensing model and choose the Azure Hybrid Benefit option.
- Complete the managed instance creation process and configure the necessary settings.
By utilizing the Azure Hybrid Benefit, organizations can seamlessly integrate their on-premises SQL Server instances with Azure, maximizing cost savings without compromising performance or scalability.
SQL Server Stretch Database
Another powerful feature to deploy hybrid SQL Server solutions is SQL Server Stretch Database. This feature allows you to dynamically stretch warm and cold transactional data from your on-premises SQL Server instance to Azure SQL Database. It provides cost-effective and transparent data access for your applications while keeping your frequently accessed data on-premises.
To enable SQL Server Stretch Database, you need to follow these steps:
- Enable Stretch Database on your on-premises SQL Server instance by specifying the appropriate settings.
- Define the Stretch Database rules to identify the data to be stretched.
- Specify the Azure SQL Database server and configure the necessary settings.
- Monitor and manage the stretched database using SQL Server Management Studio or Transact-SQL.
With SQL Server Stretch Database, organizations can achieve a balance between on-premises data storage and cloud scalability, ensuring optimal performance and cost-efficiency.
SQL Server Data Sync
SQL Server Data Sync is another feature that enables hybrid SQL Server solutions. It allows you to synchronize data across multiple SQL Server databases on-premises and Azure SQL Database. This feature is particularly useful when you want to build a distributed application or create a hybrid disaster recovery solution.
To set up SQL Server Data Sync, you need to perform the following steps:
- Install Data Sync Agent on your on-premises SQL Server instance.
- Configure the Sync Group, which defines the databases to be synchronized and the sync direction.
- Set up the sync interval, conflict resolution policies, and other synchronization settings.
- Monitor and manage the sync operation using the Azure portal or the SQL Server Data Sync application.
SQL Server Data Sync provides a reliable and seamless way to keep your data in sync across on-premises and Azure SQL databases, ensuring data availability and disaster recovery.
Conclusion
Deploying hybrid SQL Server solutions involves leveraging the strengths of both on-premises SQL Server instances and Azure SQL. Through features like Azure Hybrid Benefit, SQL Server Stretch Database, and SQL Server Data Sync, organizations can achieve scalability, cost-efficiency, and data availability across environments. By familiarizing yourself with these techniques, you can successfully administer hybrid SQL Server solutions and optimize your workload performance in line with the objectives of the Administering Microsoft Azure SQL Solutions exam.
