gRPC in the Real World: The Kubernetes Container Runtime Interface

In this article we’re going to look at how gRPC is used by Kubernetes in its Container Runtime Interface (CRI) technology. Bit first, why aren’t we seeing that much gRPC on the front-end? It’s a question that’s been asked many times now and it is one that is well worth answering. In previous installments of […]

Kubernetes Ingress goes GA

After a long time in beta, Kubernetes Ingress has gone GA in 1.19. Read more about how it impacts you, and your Ingress Controllers here Source: googleblog

Yes, you can run VMs on Kubernetes with KubeVirt

Containers and Kubernetes are awesome technologies that enable applications to run without a heavy operating system (OS), as using a virtual machine (VM) would require. Container-first, cloud-native applications are the future, but not every application is suitable to be cloud-native. KubeVirt allows you to run your virtual machines alongside your containers on a Kubernetes platform. […]

How Alibaba Cloud uses Cilium for High-Performance Cloud

A couple of weeks ago, the Alibaba team presented details on the new datapath for the Alibaba Cloud during the SIG Cloud-Provider-Alibaba meeting and also published a blog post with the technical architecture. Guess what, it is all Cilium & eBPF based. Alibaba Cloud is not the first cloud provider to directly embed Cilium. Recently, […]

How to perform a CNI Live Migration from Flannel+Calico to Cilium

Container Network Interface (CNI) is a big topic, but in short, CNI is a set of specifications that define an interface used by container orchestrators to set up networking between containers. In the Kubernetes space, the Kubelet is responsible for calling the CNI installed on the cluster so Pods are attached to the Kubernetes cluster […]

B-21 stealth bomber running Kubernetes for better SDLC experience

The new stealth U.S. Air Force B-21 bomber has taken yet another key technological step toward being ready for war, through integrated computer automation designed to streamline information, improve targeting and offer pilots organized warzone information in real-time. Air Force and Northrop Grumman developers recently completedan essential software-empowered process intended to bring greater levels of […]

New Kubernetes 1.18 Extends Ingress

Last month, the Kubernetes team released Kubernetes 1.18, which extended Ingress. The two most exciting features include a new IngressClass resource and the new pathType field. To minimize the risk for our users who want to try out these exciting new features, the Ambassador Edge Stack supports the latest version of the Kubernetes Ingress specifications. […]

Kiali with production-scale Prometheus

Of course, a definition of “production-scale Prometheus” can be as wide as the variety of cases where Istio and Prometheus are used in production. So in the context of this article, we have to make some assumptions. First of all, this article focuses on Istio using Telemetry v2, which is enabled by default starting from […]

Introducing PodTopologySpread

Managing Pods distribution across a cluster is hard. The well-known Kubernetes features for Pod affinity and anti-affinity, allow some control of Pod placement in different topologies. However, these features only resolve part of Pods distribution use cases: either place unlimited Pods to a single topology, or disallow two Pods to co-locate in the same topology. […]

How the U.S. Air Force Deployed Kubernetes and Istio on an F-16 in 45 days

Kubernetes, Istio, knative and an internally developed specification for “hardening” containers are now the default software development platform across the military. Just like almost everything else, military organizations increasingly depend on software, and they are turning to an array of open source cloud tools like Kubernetes and Istio to get the job done, according to […]
