Case Study: PayGo achieves high availability for SQL Server in AWS with SIOS DataKeeper

PayGo ensures high availability for 25 million energy customers with SIOS DataKeeper

PayGo, an integrated utility payment solution provider, faced the challenge of ensuring high availability for its mission-critical SQL Server databases in the AWS cloud. As a Windows shop, they preferred Windows Server Failover Clustering but lacked the native shared storage it requires in AWS. They sought a cost-effective alternative to expensive SQL Server Enterprise Edition that could provide rapid, automatic failover. SIOS Technology provided the solution with its SIOS DataKeeper software.

SIOS implemented its SIOS DataKeeper Cluster Edition to create a SANless cluster, using real-time block-level data replication to mimic shared storage for the failover cluster. This solution provided PayGo with the high-performance, automated failover capability they needed. The results were exceptional, with the SIOS software being described as "the most rock-solid piece of software we have." It ensured resilient operations, minimized the need for ongoing testing, and provided a cost-effective path to high availability without requiring an upgrade to SQL Server Enterprise Edition.
