CNI Benchmark: Understanding Cilium Network Performance
As more crucial workloads are being migrated to Kubernetes, network performance benchmarks are becoming an important selection criteria when deciding what network layer to leverage in a Kubernetes cluster. In this blog post, we'll explore the performance characteristics of Cilium based on extensive benchmarks that we have run in the past few weeks. Upon popular request, we are also including measurements for Calico to allow for a direct comparison.

Cilium Zero Trust Networking Protections Against CVE-2020-8554
You've probably heard about the new Man in the Middle (MITM) vulnerability in Kubernetes. If you're unfamiliar, a MITM vulnerability works by redirecting a victim's legitimate network traffic through a secret attacker on the network, where the attacker can eavesdrop or actively tamper with the victim's data before sending it to its intended destination. There have been several MITM vulnerabilities in Kubernetes, most of which take advantage of the default overly-permissive CAP_NET_RAW permissions in Kubernetes. However this vulnerability is unique in two ways:1. MITM attacks generally make use of common types of network vulnerabilities, whereas this vulnerability affects the API layer of Kubernetes itself. 2. Unlike most vulnerabilities that are assigned a Common Vulnerabilities and Exposures (CVE), there's no patch or hotfix you can deploy to protect your environment. This vulnerability is also unique in another way:if you're running Cilium without kube-proxy, you aren't vulnerable to it at all. Let's talk about how.

Multitenancy and Network Security in Kubernetes with Cilium
Multitenancy is a common pattern in Kubernetes. Many organizations deploy Kubernetes-as-a-Service, where one cluster houses many tenants and workloads. This pattern might sound familiar, as cloud computing services like AWS, Azure, and GCP have enabled multiple customers (tenants) to run their business-critical workloads in a single cluster for years.
