Hablaremos de cómo preparar el entorno, planificar cambios de versión, minimizar riesgos, y automatizar la infraestructura alrededor de la base de datos para que las actualizaciones sean más seguras y predecibles. También repasaremos retos habituales como la compatibilidad entre versiones, backups, snapshots, ventanas de mantenimiento, rollback y coordinación con aplicaciones dependientes. Una sesión práctica para entender cómo Terraform puede ayudar no solo a crear infraestructura, sino también a mantenerla y evolucionarla en entornos cloud productivos. *** Si aún no te has unido a la comunidad de Discord, ¡por favor, hazlo!

The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 **Abstract** Web Forms gave .NET developers a powerful abstraction for building reusable UI controls long before design systems were a thing. Web Components finally bring that same idea to the browser natively. This session explores how the Web Forms mindset translates into Custom Elements, Shadow DOM, and HTML templates. We’ll examine how Web Components enable design systems that work across frameworks, how they differ from server‑driven controls, and why they’re becoming a foundational layer for modern UI. Whether you’re maintaining legacy apps or building greenfield projects, you’ll leave with a practical understanding of how to apply familiar patterns in a modern, standards‑based way. **YouTube Link** TBA
