Omnichannel Enablement: 4 technology success factors

The days in which a business could thrive by serving customers through brick-and-mortar stores alone are long gone. Almost all retailers now offer a variety of online and offline channels, often with some degree of integration to ensure a smooth customer journey across different touchpoints. However, even these multichannel and cross-channel strategies are increasingly falling short of modern expectations.

Key metrics for monitoring Cilium

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.

Monitor Cilium and Kubernetes performance with Hubble

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.

Monitor Cilium-managed infrastructure with Datadog

In Part 2 of this series, we showed how Hubble, Cilium’s observability platform, enables you to view network-level details about service dependencies and traffic flows. Cilium also integrates with various standalone monitoring tools, so you can track the other key metrics discussed in Part 1. But since the platform is an integral part of your infrastructure, you need the ability to easily correlate Cilium network and resource metrics with data from your Kubernetes resources.
