How it works?
Cilium is a Kubernetes CNI that uses an eBPF-based datapath to deliver high-performance networking, identity-aware security policy enforcement, and built-in observability. It is commonly adopted by platform and DevOps teams to standardize service-to-service connectivity, apply consistent controls across microservices, and improve troubleshooting in fast-changing or multi-tenant clusters.
It typically runs as a DaemonSet on each node and integrates with Kubernetes primitives for policy management and traffic visibility; it can also support multi-cluster connectivity patterns as environments scale.
- eBPF-powered networking and efficient service load balancing in the datapath
- Support for Kubernetes NetworkPolicy plus extended identity-based policies
- Runtime flow visibility and logs to aid debugging and incident investigation
- Service-to-service encryption options for in-cluster traffic
- Multi-cluster connectivity and advanced routing capabilities
Networking, in the context of computer science and information technology, refers to the practice of connecting computers, servers, mainframes, network devices, peripherals, or other devices to exchange data and share resources. It encompasses both the physical (hardware) and logical (software) aspects of connections between devices. The primary goal of networking is to enable the sharing of data and resources, thereby improving efficiency and accessibility within and across computing environments. Networks can vary in size, ranging from simple local area networks (LANs) connecting a few devices in a single office, to complex wide area networks (WANs) spanning multiple geographic locations around the globe. Networking technologies and protocols facilitate communication and data transfer across these connections, adhering to standardized rules to ensure reliable and secure information exchange.
- Connect distributed users, applications, and services across on-premises, cloud, and hybrid environments.
- Improve performance and responsiveness through traffic optimization, routing, and load balancing.
- Increase reliability and uptime with redundancy, failover, and resilient network design.
- Strengthen security by segmenting networks, controlling access, and monitoring for threats and anomalies.
- Enable scalable growth by adding sites, devices, and bandwidth with predictable management processes.
- Support remote work and mobility with secure connectivity for branch offices and roaming endpoints.
- Enhance observability with centralized visibility into latency, packet loss, utilization, and service health.
- Simplify operations through automated provisioning, configuration management, and policy enforcement.
- Meet compliance and governance requirements with auditing, logging, and standardized network controls.
Cilium is a Kubernetes CNI that uses an eBPF-based datapath to provide high-performance networking, identity-aware security, and runtime observability. It is often chosen to reduce datapath overhead, enforce policy consistently as workloads change, and improve troubleshooting with flow-level visibility.
- eBPF-based packet processing can reduce reliance on iptables, improving scalability and tail latency on high-connection nodes.
- Identity-based policy binds rules to Kubernetes labels and workload identities, keeping enforcement stable as pods churn and IPs change.
- Layer 3 and Layer 4 network policies support least-privilege segmentation across namespaces, services, and environments.
- Layer 7 policy for supported protocols enables application-aware controls such as restricting HTTP methods and paths.
- Compatibility with Kubernetes NetworkPolicy eases adoption, while CiliumNetworkPolicy extends selectors and enables clusterwide patterns.
- Hubble observability provides flow logs, service dependency mapping, and faster root-cause analysis for drops, denies, and latency issues.
- Optional kube-proxy replacement and eBPF service load balancing can simplify the datapath and improve performance for large clusters.
- In-cluster encryption options such as WireGuard and IPsec help secure pod-to-pod traffic on untrusted or shared networks.
- Multi-cluster connectivity features support cross-cluster service communication with more consistent policy and visibility.
- Richer per-flow context reduces the need for node-level packet captures during incident response and debugging.
Cilium is a strong fit for production Kubernetes platforms that need higher throughput, deeper runtime visibility, or more expressive policy than baseline CNI plus NetworkPolicy typically provides. Key considerations include kernel and distribution compatibility, validating eBPF behavior across node images, and planning upgrades across Cilium, the kernel, and Kubernetes; the upstream Cilium documentation details supported modes and requirements.
Common alternatives include Calico, Flannel, and Weave Net, with different trade-offs around policy depth, observability, and operational simplicity.
Our experience with Cilium helped us build practical knowledge, reusable runbooks, and automation patterns for strengthening Kubernetes networking, security, and observability with eBPF across production clusters.
Some of the things we did include:
- Implemented and standardized Cilium as the CNI for new and existing Kubernetes clusters, including migration planning from legacy CNIs with phased cutovers, validation gates, and rollback procedures.
- Designed and enforced least-privilege connectivity using Kubernetes NetworkPolicies and CiliumNetworkPolicies, translating application requirements into auditable policies with clear ownership and review workflows.
- Rolled out egress controls and guardrails (DNS-aware and L7 where appropriate), reducing risky outbound access while keeping developer experience predictable and debuggable.
- Enabled kube-proxy replacement and tuned datapath settings to reduce overhead and improve latency under load, validating results with repeatable benchmarks and canary rollouts.
- Configured Hubble for flow visibility, incident triage, and policy validation, and connected telemetry into Prometheus and Grafana dashboards for actionable SLOs.
- Hardened cluster networking with encryption-in-transit where required, including key rotation considerations and performance impact analysis for different traffic profiles.
- Implemented ingress and traffic management patterns alongside Istio in environments that needed both service mesh features and kernel-level enforcement.
- Automated installation, upgrades, and configuration drift detection using GitOps practices with Argo CD, including environment overlays, version pinning, and safe upgrade runbooks.
- Validated multi-tenant and multi-namespace isolation models, documenting allowed flows and exception handling to support audits and reduce “tribal knowledge” dependencies.
- Built day-2 operational playbooks for common failure modes (policy regressions, node churn, MTU issues, conntrack pressure) and trained platform teams on safe operations and troubleshooting.
This experience helped us accumulate significant knowledge across multiple Cilium use-cases—migration, policy enforcement, observability, performance tuning, and day-2 operations—and enables us to deliver high-quality Cilium setups that are maintainable, measurable, and reliable in real production environments.
Some of the things we can help you do with Cilium include:
- Assess your current Kubernetes networking and security posture and deliver a prioritized findings report covering datapath, policy coverage, and operational risks.
- Define an adoption roadmap for rolling out eBPF-based networking across clusters with clear milestones, rollout patterns, and rollback controls.
- Implement and configure Cilium on new or existing Kubernetes clusters, including migration planning from legacy CNIs and safe cutover procedures.
- Design and enforce least-privilege network guardrails using Kubernetes NetworkPolicies and Cilium policy features to support compliance and reduce blast radius.
- Automate Cilium configuration and policy delivery with IaC and GitOps workflows (e.g., Terraform and Argo CD) so changes are versioned, reviewed, and promoted safely.
- Set up observability for flows, drops, DNS, and latency, aligning dashboards and alerts with SLOs and incident response runbooks.
- Optimize performance and cost by tuning datapath settings, reducing noisy east-west traffic, and right-sizing cluster and networking parameters.
- Troubleshoot service-to-service connectivity, DNS, and intermittent drops using eBPF-driven visibility to shorten MTTR.
- Harden day-2 operations with upgrade strategies, compatibility checks, rollback plans, and reusable runbooks for reliable multi-environment operations.
- Enable your teams with hands-on training and documentation for policy authoring, troubleshooting workflows, and ongoing Cilium operations.
