SIOS Technology Corp. has emerged and established itself very fast among the big fishes in the global markets in the field of high availability and disaster recovery solutions. Why SIOS solutions are among the top is for the simple reason of availability and elimination of data loss for critical Windows and Linux applications running across heterogeneous enterprise environments viz virtual, cloud, physical, and hybrid cloud. On the same note, SIOS clustering software has become essential for enterprises having an IT infrastructure with applications needing a high degree of resiliency along with ensuring near to 100% uptime with no compromise with performance or data thus protecting their business ecosystem from any kind of local failures and regional outages be it planned or unplanned. PayGo, the latest launch by SIOS Technology Corp., ensures the high availability of SQL Server in the AWS cloud with SIOS DataKeeper.

SIOS Technology Corp., established in 1999 and headquartered in San Mateo, California has offices worldwide. SIOS, SIOS Technology, SIOS DataKeeper, SIOS Protection Suite, Clusters Your Way, and associated logos are registered trademarks or trademarks of SIOS Technology Corp. Why customers prefer SIOS is for building dependable operations, high performance, and ease of use. That has made SIOS an industry pioneer in providing IT Resilience via intelligent application availiability thus mitigating a large number of risks associated. PayGo uses SIOS DataKeeper on Amazon Web Services (AWS). It does so by utilizing Elastic Compute Cloud (EC2) virtual servers with a solid-state drive (SSD)-only storage. It results in creating a rapid, automatic failover environment that eventually ensures high availability (HA) for the enterprise’s key business applications on SQL Server. PayGo, in fact, is an integrated utility payment solution provider. It handles the largest energy company prepay ecosystem in the United States.


PayGo basically, as of now, is running four production environments on Amazon cloud. The fifth one is about to come anytime. The environment comprises of SQL Server 2017 Standard Edition running on Windows Server 2012 R2. But soon after testing is completed, it will migrate to Windows Server 2019. Chad Gates, Senior Director of Infrastructure and Security, PayGo says, “Our backend SQL Servers hold terabytes of data that must be available 24×7. As a Windows shop, we prefer to use Windows Server Failover Clustering (WSFC) for data protection and continuous operation in case of any failures. But WSFC requires some form of shared storage, like a storage area network (SAN) and that isn’t natively available in AWS.”

Chad concludes, “SIOS DataKeeper Cluster Edition overcame the problem caused by the lack of shared storage. Its use of a mirrored drive looks like shared storage to the WSFC. It was exactly what we wanted.” Interestingly, SIOS DataKeeper also met PayGo’s other three criteria better than any other solution. On the results achieved, Chad says, “We have been using SIOS DataKeeper for several years now, and it has proven to be the most rock-solid piece of software we have.”

Frank Jablonski, VP of global marketing, SIOS Technology says, “Whether you need to protect applications on a physical server, a private cloud, a public cloud or a hybrid cloud, you need to meet the same SLAs for application availability regardless of location. Applications running in clouds also need to be protected against the inevitable cloud outage through the use of availability zones and regions with automated intelligent failover. PayGo is using SIOS to provide a fast, easy way to deploy applications in a high availability environment in the AWS cloud while continuing to use Windows Server Failover Clustering.”
