Christian Beneke
Trade Republic's Journey to Open Source Observability - How we migrated from DataDog to Grafana LGTM.
In the current environment, cost awareness on top of a great developer experience is more relevant than ever. As an answer to that, at Trade Republic, we have decided to re-evaluate the cost-to-use of our observability offering and ruled against continuing the path forward with Datadog. In this talk I will provide an overview of our mission to migrate to an alternative stack, which outcome we have so far and what we have learned.

Modernizing CI/CD Pipelines: A Case Study on Building a Robust, Secure, and Efficient System for Cloud-Native Development
In the dynamic sphere of cloud-native development, constructing robust, secure, and efficient CI/CD systems is not just desirable but essential. This talk will take you on a journey through the modernization of our build pipeline and CI/CD systems, specifically focusing on our project, Parca - a performance analysis tool that operates at the kernel level using eBPF technology.
We will explore the challenges of ensuring security and compatibility across various kernel versions, a critical requirement for kernel-level operations like those used by Parca. Our solution is a fully open-source, cross-platform CI/CD pipeline, uniquely tailored to meet Parca's intricate needs. This pipeline exemplifies the power of modern tooling, stepping beyond the limitations of traditional makefiles.
Critical aspects of our discussion will include:

• Byte-by-Byte Reproducible Builds: Delving into how we achieve exact replicability in our builds to enhance security and fortify the supply chain against vulnerabilities.
• Locally Reproducible CI/CD: Demonstrating the methodologies that ensure what is run and tested locally can be precisely reproduced on remote CI servers, bridging the gap between local development and production environments.
• Modern Tooling for CI/CD Pipelines: Showcasing how tools like Jetpack Devbox (easy way to use NixOs), Dagger, Mage, GitHub Actions, and Zig's build system have revolutionized our approach to building CI/CD pipelines.
• Collaborative Efforts and Open-Source Innovations: Highlighting the cooperative nature of our project and how open-source tools and community contributions have been instrumental in our success.

Attendees will gain valuable insights into creating a secure, adaptable, and efficient pipeline in an open-source environment. This talk will detail our journey and solutions and provide practical lessons for those looking to modernize their CI/CD systems in the cloud-native ecosystem.
Join us to explore the frontiers of CI/CD modernization and learn how your projects can benefit from these cutting-edge practices and tools.
