Cloud Providers

Most cloud providers have their own custom CNIs, resulting in operational complexity for customers operating in multi-cloud environments. For example, the configuration and capabilities of the AWS VPC CNI and OpenShift SDN are significantly different. This fragmentation increases overhead in installing, operating, and troubleshooting network interfaces across cloud environments.

Cilium addresses these issues by presenting a unified networking solution tailored for Kubernetes that is compatible across various clouds, providing a consistent workflow that simplifies operations. Using eBPF, Cilium extends beyond Kubernetes basic networking capabilities, offering enhanced observability, security, and reduced latency. Major cloud providers, including Google Cloud, AWS, Azure, and Alibaba, have all standardized on Cilium for Kubernetes networking and security as a testament to its scalability, performance, and rich feature set.

Hetzner Cloud Adopts Cilium for a Cloud Native Ingress Architecture

Hetzner Cloud, a leading German public cloud provider, recently overhauled its ingress architecture to pursue modern and scalable cloud services. Hetzner was scouting for a Kubernetes-native solution with ECMP, firewall, IPv6, and DSR capabilities. Cilium emerged as the ideal choice. Before adopting Cilium, Hetzner ran tests deploying different Cilium configurations in a Kubernetes cluster to benchmark RPS and throughput and then checking the CPU usage as a metric to compare the tests. These tests showed Cilium provided a massive increase in both RPS and throughput while still reducing CPU usage.

With Cilium's Kubernetes-native support, scalability, enhanced security, IPv6 compatibility, and efficiency with DSR, Cilium is a compelling choice for cloud providers. The results of Hetzner Cloud's performance tests highlight the value of adopting Cilium to elevate performance, security, and scalability in the cloud infrastructure landscape.
