Microsoft Workloads on AWS Blog



This article provides a comprehensive guide to implementing a SQL Server Stretch Failover Cluster Instance (FCI) on Amazon EC2 using EBS Multi-Attach on io2 volumes and Windows Server Storage Replica across multiple Availability Zones.

  • Solution involves a 4-node cluster across two Availability Zones
  • Uses Amazon EBS Multi-Attach io2 volumes for shared storage
  • Implements Windows Server Storage Replica for cross-AZ data replication
  • Requires Windows Server 2016 or later, SQL Server Enterprise edition
  • Enables high availability and disaster recovery capabilities

Key benefits include cross-AZ failover, improved business continuity, and the ability to maintain database services during infrastructure failures. The solution provides a robust approach to implementing resilient SQL Server deployments on AWS.
