All U.S.Techs technology is developed in-house on Microsoft platforms. Our Web servers are scalable using Windows load-balancing services. The database servers use replication to achieve server redundancy. The infrastructure exists at multiple site locations to ensure continuous operation in the event of a disaster. The primary site is clean power, with both battery and generator back-up supplies, using multi-homed connections to insulate against circuit failure. We are CISSP security certified. Both ASP and ASP.NET platforms have been used for our applications. All data is stored using MS SQL Server 2000 and other processes, executed through the use of COM components and .NET assemblies.
