Compare Istio and Cilium - features, pros, cons, and real-world usage from developers. Table 1 shows the performance results of Istio, Cilium, and XLB. Understanding Cilium We aimed to compare and share our experience on three popular open-source service meshes: Cilium, Linkerd and Istio (Sidecar and Ambient). Oct 21, 2024 · For the Istio test, we used Istio’s ambient mode, with a waypoint proxy in every service namespace, and default install parameters. Istio, Envoy, and Cilium serve different but complementary purposes in modern cloud-native architectures. Traefik using this comparison chart. For example, Istio uses RBAC filters from Envoy upstream to authorize actions by identified clients. Cilium secures network connectivity between Kubernetes services by adding high-level application rules utilizing eBPF filtering technology. We also considered specific scenarios by combining Istio service mesh and Cilium CNI and also enabling and disabling mTLS. Both Istio and Cilium provide mechanisms for service discovery, allowing microservices to locate and communicate with each other using logical service names rather than hard-coded IP addresses. This article delves deep into the intricacies of Cilium and Calico, comparing their features, strengths, and weaknesses to help you make an informed decision for your Kubernetes deployments. In comparison to the baseline Cilium’s performance is slower by 20–30% for Internal communications and 30 Integration with Istio This page helps you get started using Istio with a Cilium-enabled Kubernetes cluster. How are they implemented? Istio brought complexity into the table at the end. Should I choose Istio or Cilium for my microservices with Kafka on EKS? Insights from complex networking experiences. Cilium is an open-source, highly scalable Kubernetes CNI solution developed by Linux kernel developers. ## gRPC Mode: L4 and L7 Part of the Application Model. It aims to simplify application networking with unified control, reliability, observability, extensibility, and security. Cilium improves Istio by avoiding redundant net-working stack in the kernel and using a global proxy for all services. But will adding Cilium help if you are using Istio service mesh? Architectural Approaches: Istio vs. Linkerd prioritizes simplicity and performance. L7Policy filter for L7 access control is quite different from how Istio enforces L7 policy. Jun 23, 2024 · Istio and Cilium are popular service mesh used to improve Kubernetes security by providing mTLS, observability, traffic control, etc. Cilium's service mesh capabilities reduced management complexity, improved manageability with a smaller footprint, and offered a more user-friendly experience for defining network policies. In order to make our test scenarios similar, we had to turn on a few non-default features in Cilium, including WireGuard encryption, L7 Proxies, and Node Init. These mechanisms help manage service resilience by intelligently retrying failed requests and isolating unhealthy services. In parallel, Cilium automatically optimizes some aspects of Istio such as shortening the sidecar network path injection and avoiding unencrypted data exposure between application and the sidecar. Discover the fastest, most secure CNI for your cluster and boost your application's efficiency. However, they are designed with different purposes in mind, and understanding these differences is crucial to selecting the right tool for your use case. As a result, this Cilium mesh may not support all the features of the Envoy proxy. This comparison covers the following areas: Stop Using the Wrong CNI in 2026: Flannel vs Calico vs Cilium When I first built my Kubernetes cluster, I didn’t even think about the CNI. This flexibility demands operational investment—expect dedicated engineering time for upgrades and troubleshooting. Cilium, based on eBPF, offers cloud-native networking and security. We selected the best ones and compared them across multiple uses cases, from easy of installation to security and traffic management features. There are many Service Mesh Technologies out there. It brings all Istio features to Cilium while allowing Cilium to enforce L7 policies via the Istio-managed sidecar. Why did Cilium win over Istio for number choice fo service mesh?
