Kubernetes the Hard Way: A Live Journey
While many users interact with Kubernetes using abstractions like YAML files, the intricate interactions between Kubernetes components often remain hidden. This technical session takes you on a live journey through the "hard way" of setting up Kubernetes, peeling back the layers of abstraction to reveal how its core components—such as the API Server, etcd, Controller Manager, Scheduler, and kubelet—interact to orchestrate workloads. By tracing the lifecycle of a Pod from kubectl create to running container, we'll explore how often-overlooked components like the cloud controller manager and kube-proxy play critical roles in cluster operations. Through this live demonstration, attendees will gain a deep understanding of Kubernetes' internal mechanics, empowering them to troubleshoot more effectively, make informed architectural decisions, and unlock the true potential of Kubernetes in production environments.
From Keys to Trust: A Beginner's Guide to Cryptography, TLS, and Zero Trust Security
In today's cloud-native ecosystems, secure communication is the cornerstone of trust. But how do we build that trust, starting from the basics of cryptography and scaling up to zero trust architectures? This session takes you on a journey from the fundamentals of encryption and public-private key pairs to the intricacies of TLS, mutual TLS (mTLS), and X.509 certificates. Along the way, we'll explore how these technologies work together to protect against eavesdropping, tampering, and identity theft. Finally, we'll connect the dots to zero trust, showing how secure communication is essential for verifying identities and ensuring trust in every interaction. Whether you're new to cloud administration or looking to solidify your security fundamentals, this beginner-friendly talk will equip you with the knowledge to build and maintain secure systems.
Why Allyship Matters and Your Role in Creating a More Diverse Cloud Native Community
Despite many DEI initiatives, diversity in open source is still lacking. That's not only bad for underrepresented groups, it's also bad for OSS (studies have shown time and again that diverse teams produce better outcomes). While there isn't much you can do about the industry's hiring practices, you can help make a difference!
As companies scale back on DEI efforts, community-driven change becomes essential—and that’s where allies come in. Minorities are, by definition, in the minority, and their advocacy alone has limits. Allies have the power to amplify underrepresented voices, raise awareness among peers, and advocate for change. When allies take a stand for inclusivity, accessibility, and ethical responsibility, they hold the power to influence the industry's values and priorities.
Join this panel with CNCF Deaf and Hard of Hearing WG members to learn how you can drive meaningful change and contribute to a more diverse, inclusive, and innovative open-source community.
