Testimonials
We got to meet Michael from MeteorOps through one of our employees. We needed DevOps help and guidance and Michael and the team provided all of it from the very beginning. They did everything from dev support to infrastructure design and configuration to helping during Production incidents like any one of our own employees. They actually became an integral part of our organization which says a lot about their personal attitude and dedication.
Good consultants execute on task and deliver as planned. Better consultants overdeliver on their tasks. Great consultants become full technology partners and provide expertise beyond their scope.

How it works?
Cilium is a Kubernetes networking, security, and observability solution built on eBPF, used by platform and DevOps teams to provide scalable service connectivity and enforce fine-grained network policy. It helps organizations reduce complexity in cluster networking by applying identity-aware controls and visibility across services, making it useful for multi-tenant platforms and microservice-heavy environments.
It is typically deployed as a CNI in Kubernetes clusters (including managed offerings) and integrated into platform workflows for policy management, traffic observability, and operational troubleshooting. For broader Kubernetes architecture context, see Kubernetes consulting.
- High-performance datapath and service load balancing using eBPF
- Kubernetes NetworkPolicy enforcement and additional policy constructs for guardrails
- Layer 7-aware visibility and flow logs to support debugging and incident response
- Support for cluster-to-cluster and multi-network connectivity patterns
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.
Cilium is a Kubernetes CNI that provides networking, security, and observability using an eBPF-based datapath. It is commonly used to improve performance and runtime visibility while enforcing identity-aware network controls in dynamic clusters.
- eBPF-based datapath that can reduce reliance on iptables-heavy processing and improve throughput and tail latency in busy clusters.
- Identity-based policy enforcement using Kubernetes labels and service identities, making rules more stable than IP-based controls as pods churn.
- Layer 3 to Layer 7 policy capabilities for supported protocols, enabling controls such as restricting HTTP methods and paths in addition to basic allow and deny rules.
- Compatibility with Kubernetes NetworkPolicy plus CiliumNetworkPolicy extensions for advanced use cases such as clusterwide policies and richer L7 rules.
- Integrated observability through Hubble, providing flow logs, service dependency mapping, and faster diagnosis of dropped or misrouted traffic.
- kube-proxy replacement and eBPF-based service load balancing options that can simplify the datapath and improve scalability for high-connection workloads.
- Multi-cluster connectivity features to support cross-cluster service communication and consistent policy enforcement across environments.
- Encryption for pod-to-pod traffic in transit using mechanisms such as WireGuard or IPsec, supporting stronger zero-trust defaults on untrusted networks.
- Improved troubleshooting primitives with per-connection visibility and enriched telemetry, reducing dependence on node-level packet captures.
- Works well with platform engineering practices where networking and security are managed as code, validated in CI/CD, and audited over time.
Cilium is a strong fit for production Kubernetes environments that need higher performance networking, deeper runtime visibility, or more expressive policy than baseline CNI plus NetworkPolicy can provide. Trade-offs include added operational complexity, kernel and distribution compatibility constraints, and the need to validate eBPF behavior across node images and upgrade paths; the upstream Cilium documentation is a useful reference for 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.
