Microsoft Workloads on AWS Blog

This article provides a detailed guide on deploying a SQL Server Failover Cluster Instance (FCI) across three AWS Availability Zones using Storage Spaces Direct (S2D).

  • Requires three Amazon EC2 Windows Server 2022 instances across different Availability Zones
  • Uses local EBS volumes to create a shared storage pool with Storage Spaces Direct
  • Provides high availability by enabling automatic failover between cluster nodes
  • Requires SQL Server Enterprise Edition for clusters with more than 2 nodes
  • Enables geographic resilience for mission-critical databases

Key steps include domain joining instances, configuring cluster nodes, enabling Storage Spaces Direct, installing SQL Server, and creating a failover cluster with shared storage across three availability zones.
