Flatcar Linux: A Modern OS for the Always-On Infrastructure

In this episode, we dive deep into Flatcar Linux, an immutable Linux distribution designed for always-on infrastructures. The discussion covers the architecture and features of Flatcar, including its self-updating capabilities and minimal attack surface. We explore the use of Ignition for provisioning, the role of Systemd and its extensions, and the detailed update process via an update server. The Flatcar maintainers also highlight the benefits of full-disk encryption, node-level metrics, and operational insights available through tools like Nebraska and Node exporter. Guest speakers include Flatcar maintainers and engineers from Microsoft, who share their experiences and insights on managing and maintaining Flatcar at scale.

Evolving Platform Engineering & The Rise and Fall of Kubernetes with Evelyn Osmond

In today's episode of Cloud Native Compass, we dive deep into the world of platform engineering and Kubernetes. Our guest, Evelyn Osmond, head of platform at a Munich-based energy trade startup, shares her extensive experience and insights on building and maintaining platforms. We discuss the future of scripting, the challenges of release management, and the importance of continually asking 'why' in both technical and business contexts. Join us as we explore the benefits and potential pitfalls of Kubernetes, the necessity of understanding the 'why' behind our choices, and the evolving landscape of cloud-native technologies. Whether you're a junior developer or a seasoned engineer, there's something here for everyone.
