Istio - Service Mesh to provide Traffic Control, Security and Observability for Kubernetes
Ambient interoperability with sidecarsAll the Pods don't need to use the new Ambient mode. You can have some Pods using sidecars while others are using Ambient. Let's create a new namespace called httpbin: kubectl create namespace httpbinTo use sidecars in this namespace, you need to label it accordingly: kubectl label
L7 authorization policiesL4 policies are useful but may not be sufficient for your needs. For example, youβll be able to send any request to the web-api service from the sleep pod while you may only want to allow requests with the GET method. In order to have any L7

The goal of this workshop is to enable the audience to identify and design networking solutions at several levels in the OSI stack.
In this article, weβll explain what a service mesh is, why itβs needed, and lay out the service mesh startup landscape as it exists today.
What is a service mesh? How does it work? Why would you want a service mesh in your application and what can it provide? Get a quick overview of service mesh and Kubernetes.
