Bank Ensures High Availability, Promotes Business Growth, and Boosts Performance with New Database Solution "Our tests showed that SQL Server 2012 will give us much higher availability, and we will definitely decrease downtime for our customer applications. This improvement will positively affect our customers." Wilson Yoshio Okamoto, IT Manager, Banco Bradesco

One of Brazil’s largest banks, Banco Bradesco, has more than 65 million customers throughout the country. Many of these customers depend on the bank’s online banking and customer service applications. To make sure these mission-critical applications are available around the clock, the bank is implementing a Microsoft high-availability and disaster-recovery solution based on Microsoft SQL Server 2012. With that high availability ensured, the bank can provide better customer service. The solution will also help support the bank’s growth, and it improves performance by up to 30 percent.
