High Performance and High Availability for SQL Servers on AWS
SQL Server is typically deployed in a standalone configuration within a single Amazon EC2 Availability Zone, making it vulnerable to downtime if there is an outage in the Availability Zone.
Through a joint effort with Amazon, SIOS clustering software enables native SQL Server Failover Clustering for AWS deployments without the need for shared storage. Create a SQL Server cluster using only local storage and add SIOS software for host-based, block level replication that keeps data synchronized between nodes and enables failover across EC2 Availability Zones.
SIOS Technology has achieved AWS Microsoft Workloads Competency Status. This designation recognizes that SIOS provides proven technology and deep expertise in helping customers in the migration, deployment and management of Microsoft-based applications on AWS, specifically with workloads based on Microsoft SQL Server.
SQL Server Cluster in the Cloud: Protected by SIOS
SIOS SANLess clusters provide complete protection without the limitations of SQL Server AlwaysOn Availability Groups or traditional shared storage based SQL Server AlwaysOn Failover Cluster Instances (FCI).
SIOS SANLess clusters support multi-Availability Zone deployments, unlimited databases per SQL Server instance, and applications that rely on the Microsoft Distributed Transaction Coordinator.
