📖 AWS re:Invent 2025 - Grupo Tress Internacional's .NET modernization with AWS Transform (MAM320)

In this video, Grupo Tress Internacional shares their transformation journey from .NET Framework 4.6 to .NET 8 using AWS Transform for .NET. Armando Valenzuela, Head of Engineering, explains how they modernized a critical payroll stamping service processing 11.3 million documents daily for 4.4 million employees. The migration from Elastic Beanstalk to Lambda achieved 40% cost reduction, 70% reduction in development hours, and eliminated Windows licensing costs. The team used AWS Transform to automatically migrate 135,000 lines of code, cleaned 23 unnecessary NuGet packages, and leveraged Amazon Q Developer for manual fixes and validation. They deployed on Graviton-based Lambdas, achieving zero downtime during peak payroll periods. The presentation includes a live demonstration of AWS Transform in Visual Studio, showing the IDE integration, transformation process, and how Amazon Q assists with code modernization tasks like replacing Entity Framework with Entity Framework Core.
