Enterprises must adhere to industry-specific regulations for application security. This is especially crucial in sectors like finance and healthcare, which have very strict standards. A common practice among such firms involves implementing network policies in their Kubernetes clusters to manage traffic flow. However, this often creates challenges during solution development due to uncertainties about allowed protocols and necessary communication patterns, particularly when these policies are applied to long-running applications. Hubble emerges as an ideal tool for illuminating all network activity within a Kubernetes cluster. It logs and displays every transmitted byte in the Hubble console. Thus, Hubble not only reveals ongoing traffic but also identifies traffic blocked by network policies. copebit advises clients who employ network policies to integrate Hubble. This enhances visibility, facilitates network policy management, and provides comprehensive insights into cluster traffic patterns.

Applications requiring external cluster access need specific ports or paths open. Historically, this was achieved using node ports, load balancers, and ingresses. Cilium enhances this process by offering superior performance and security.

Cilium’s advanced built-in ingress operates directly in kernel space using eBPF. This approach not only boosts performance but also removes the need for an additional third-party ingress controller. Importantly, it remains fully compatible with standard Kubernetes service configurations.

For those considering a service mesh, Cilium presents an efficient solution. It eliminates the need for sidecars in implementing mTLS between microservices. The Cilium Service Mesh provides this functionality in a sidecar-less manner, along with HTTP routing and exceptional visibility and observability features.

At copebit, we have developed extensive expertise in integrating these two key Cilium functionalities.
