Azure SQL Always On Availability Groups

Overview

Azure Always On Availability Groups provide a high availability and disaster recovery solution for SQL Server, ensuring continuous data protection and minimal downtime for your applications. They allow you to achieve high availability and load balancing for your critical databases, making it easier to manage and scale your SQL Server deployments on Azure.

Core Functionality

• High Availability: Ensures that your SQL Server databases remain available even in the event of hardware failures or software issues. Automatically fails over to a secondary replica in the event of a primary replica failure.
• Disaster Recovery: Protects your data by replicating it to multiple Azure regions. In the event of a regional outage, you can fail over to a secondary region.
• Load Balancing: Distributes read workloads across multiple replicas, improving performance and ensuring that your applications can handle increased traffic.
• Data Protection: Provides continuous data protection by replicating data changes from the primary replica to secondary replicas. Ensures that your data is always up to date and protected.
