Azure SQL High Availability

A comprehensive tutorial for achieving high availability in Azure SQL Databases.

Introduction

High availability is crucial for ensuring your database services remain accessible and reliable. It minimizes downtime and protects your business.

Key concepts include replication, failover, and disaster recovery.

Replication

Azure SQL Database offers built-in replication that automatically replicates data to a secondary region.

This ensures data is available even if the primary server fails.

Configurable replication types include synchronous and asynchronous replication.

Failover

Failover allows your database to seamlessly switch to a backup server if the primary server fails.

Automatic failover minimizes downtime during recovery.

Disaster Recovery

Disaster recovery ensures your database can be restored from backups in a different region.

Implementing a disaster recovery plan significantly reduces the impact of outages.

Key Features

Azure SQL Database offers features like read replicas, geo-replication, and automatic failover.
