Chasing the Leak, How the eBPF Bee can help you with workload profiling without any code change
In modern cloud-native environments, achieving comprehensive observability is crucial for maintaining optimal performance and reliability. Traditional monitoring approaches often fall short in providing the granular insights necessary to diagnose complex issues within Kubernetes clusters. This presentation explores the integration of continuous application profiling into Kubernetes observability practices, leveraging both native and eBPF-based methods.
Transitioning from NetworkPolicies to AdminNetworkPolicy
In this session, we will delve into the evolution of Kubernetes network policies, starting with the foundational aspects of traditional namespace-scoped NetworkPolicies. Transitioning from theory to practice, we will explore the AdminNetworkPolicy in depth. By the end of this session attendees will learn how to define and implement ANPs, leveraging their features to establish a robust zero-trust security framework across the cluster in a solo or a multi tenant environment.
How to rollout an update for a CNI without breaking the World Wide Web
