Case Study: DSK Bank achieves 24/7 online banking reliability with Microsoft SQL Server and AlwaysOn

Already secure and reliable online banking strengthened by core database upgrade

DSK Bank, a major financial services provider in Bulgaria, sought to improve the reliability and availability of its DSK Direct online banking platform for its corporate and SMB users. The existing system, running on Microsoft SQL Server, experienced occasional outages during peak times and could not meet the demand for a truly always-available global service.

Microsoft addressed this challenge by implementing a solution using SQL Server 2016 with AlwaysOn Availability Groups across multiple data centers. This upgrade provided a 25% increase in system capacity, guaranteed 99.99% uptime, and reduced potential disaster recovery time from eight hours to just two minutes. For Microsoft, the solution also delivered enhanced security, compliance, and operational cost savings for the bank.
