Understanding Ciliums Architecture

Discover how Cilium's innovative architecture harnesses eBPF technology to enhance Kubernetes networking and security.

Cilium stands out by leveraging eBPF, a cutting-edge technology that runs directly within the Linux kernel. This integration enables efficient networking with advanced security measures. At its core, Cilium manages pod networking using the Container Network Interface (CNI), ensuring seamless communication among pods while enforcing strict security policies to allow only authorized traffic.

Key Features of Cilium

Cilium offers several robust features to optimize your Kubernetes environment:

  • Network Policies: Secure pod-to-pod communications by enforcing policies that prevent unauthorized access.
  • Services and Load Balancing: Efficiently route traffic and distribute loads evenly among pods, ensuring high availability.
  • Bandwidth Management: Regulate traffic consumption per pod to prevent network congestion.
  • Flow and Policy Logging: Monitor network traffic in real time and gain insights into policy enforcement across your cluster.
  • Security and Operational Metrics: Obtain deep visibility into your cluster’s security posture and overall performance.
