### 🎤 Talks

#1: Facing the Monolith: Containerization Challenges and Best Practices for Legacy Apps – Ricardo Magalhães, DevOps Engineer @ synvert xgeeks

Abstract: Many organizations face significant challenges when it comes to modernizing legacy applications. This talk dives into the potential of containerization as a key technique for deconstructing monolithic legacy systems and paving the way for a robust microservices architecture.

We will cover the unique challenges involved in containerizing legacy applications, including platform compatibility issues, complex dependency management, and effective testing strategies. Attendees will gain valuable insights into overcoming these hurdles through real-world examples and best practices. By the end of this session, you'll be equipped with the knowledge and tools to start your own containerization journey, unlocking the full potential of your applications and driving your organization towards a more modern, scalable, and agile future

#2: Boring Architecture, Bright Future

Speaker: Francisco Afonso – Senior Backend and Data Engineer @ tb.lx

Abstract:

This talk will cover the architectural changes that led us away from a complex GraphQL Federation Service to a simple REST API. We’ll share why we migrated our core service from Python to Rust to meet performance demands, reduce costs, and streamline operations — and how a “boring” architecture can lead to a much brighter future.

#3: RBAC to ReBAC – Zanzibar Google Implementation

Speaker: Eric Leijonmarck – Software Engineer @ Grafana

Abstract:

Crafting a scalable Identity and Access Management (IAM) system is no easy task. RBAC has long been the go-to model, but modern systems often suffer from "role explosion."

In this talk, we’ll explore how Grafana Labs transitioned to Relationship-Based Access Control (ReBAC), inspired by Google Zanzibar, to address growing complexity with a more expressive, flexible, and manageable approach to authorization.
