Cilium is a Container Network Interface (CNI) for securing and load-balancing network traffic in your Kubernetes environment. As a CNI provider, Cilium extends the orchestrator’s existing network capabilities by giving teams more control over how they build their applications and monitor traffic. For example, vanilla Kubernetes installations typically rely on traditional firewalls and Linux-based network utilities like iptables to filter pod-to-pod traffic by an IP address or port.

In Part 1, we looked at some key metrics for monitoring the health and performance of your Cilium-managed Kubernetes clusters and network. In this post, we’ll look at how Hubble enables you to visualize network traffic via a CLI and user interface. But first, we’ll briefly look at Hubble’s underlying infrastructure and how it provides visibility into your environment.

AWS provides multiple ways to deploy containerized applications. From small, ready-made WordPress instances on Lightsail, to managed Kubernetes clusters running hundreds of instances across multiple availability zones. When deciding on the architecture of your application, you should consider building it serverless. Being free from (virtual) server management enables you to focus more on your unique business logic while reducing your operational costs and increasing your speed to market.

Hyperconverged infrastructure (HCI) is a data center architecture that uses software to provide a scalable, efficient, cost-effective way to deploy and manage resources. HCI virtualizes and combines storage, computing, and networking into a single system that can be easily scaled up or down as required.
