Kuberneteshttps://learncloudnative.com/category/kubernetes
Exploring Kubernetes VolumesRunning stateful workloads inside Kubernetes is different from running stateless services. The reason being is that the containers and Pods can get created and destroyed at any time. If any of the cluster nodes go down or a new node appears, Kubernetes needs to reschedule the Pods. When Pods get rescheduled, what happens with data? This article talks about Kubernetes Volumes and how to use them to store the data outside of your containers.https://learncloudnative.com/blog/2020-11-11-kubernetes-volumes

Service Meshhttps://learncloudnative.com/category/service-mesh
What is circuit breaking?A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit. How does that apply to your services and Istio service mesh?https://learncloudnative.com/blog/2020-02-28-circuit_breakers_in_istio_explained

Firebasehttps://learncloudnative.com/category/firebase
How to configure Firebase emulators with Next.js?Firebase emulators are a suite of Firebase service emulators that allow you to run and test your applications locally. This article describes how to configure and use them with Next.jshttps://learncloudnative.com/blog/2022-03-04-firebase-emulators

Kuberneteshttps://learncloudnative.com/category/kubernetes
Container Lifecycle HooksThe concept of hooks is well-known in the tech world. Events usually trigger hooks, and they allow developers to react to those events and run some custom code. But how can you do the same in the context of Kubernetes and containers?https://learncloudnative.com/blog/2021-05-03-container-lifecycle-hooks

Service Meshhttps://learncloudnative.com/category/service-mesh
How to apply Istio DestinationRule across the mesh?An interesting question came up today in Istio Slack where someone asked if and how one can apply DestinationRules globally to all workloads inside the cluster. The short answer is yes, and this article will explain how to do it.https://learncloudnative.com/blog/2023-02-03-global-dr
