The article discusses the deployment of multi-AZ, multi-region SQL Server Failover Cluster Instances (FCIs) in Azure, focusing on high availability and disaster recovery. While SQL Server Always On Availability Groups are widely covered, FCIs offer an alternative without Enterprise Edition costs. The article outlines the challenges posed by cross-zone and region configurations and introduces a PowerShell script that automates networking setup. This script establishes vNets, secure peering, and Network Security Groups, providing a solid foundation for resilient infrastructure and ensuring effective FCI operations in Azure's multi-region environment.
A well-configured network is critical for deploying SQL Server FCI across multiple availability zones and regions in Azure, enabling seamless high availability and disaster recovery.
This guide addresses the complexities involved in configuring SQL Server FCI in Azure, emphasizing the necessity of proper networking using PowerShell scripting for resilience.
