How To Implement Istio Ambient Mesh in GKE or AKS

Why Do You Need Istio Ambient Mesh?

It is given that Istio is a bit resource intensive due to sidecar proxy. Although there are a lot of compelling security features that can be used, the whole Istio (the sidecar) has to be deployed from day one. Recently, the Istio community has reimagined a new data plane — ambient mode — which will be far less resource-intensive. Istio ambient mesh is a modified and sidecar-less data plane developed for enterprises that want to deploy mTLS and other security features first and deploy an advanced network later.

Ambient mesh has two layers:

Getting Started With Distributed SQL on Azure Kubernetes Service

Microsoft’s Azure Kubernetes Service (AKS) offers a highly available, secure, and fully managed Kubernetes service for developers looking to host their applications on containers in the cloud. AKS features elastic provisioning, an integrated developer experience for rapid application development, enterprise security features, and the most available regions of any cloud provider.

YugabyteDB is a natural fit for AKS because it was designed to support cloud native environments since its initial design.

Upgrading Kubernetes Worker Nodes in GKE, AKS, and EKS

Kubernetes is a popular container orchestration platform that you can deploy on-premise or in the cloud. In this article, you will learn about Kubernetes upgrade options in Google Kubernetes Engine (GKE), Azure Kubernetes Service (AKS), and Amazon Elastic Container Service for Kubernetes (EKS).

What is a Kubernetes Cluster?

A cluster is a unit that includes several Kubernetes pods. A pod is a set of containers, with facilities to allow containers to communicate and share data between them. A cluster consists of the following components:

Export Kubernetes Logs to Azure Log Analytics With Fluent Bit

Every container you run in Kubernetes is going to be generating log data. No one has time to go through and regularly check individual container logs for issues, and so in production environments, it is often required to export these logs to an aggregator for automated analysis.

If you're using Azure, then Log Analytics may be your log aggregator of choice, and so you need a way to export your container logs into Log Analytics. If you are using AKS, you can deploy the Azure Monitor solution which does this for you, however, if you are running your own cluster, or even using another cloud provider and still want to use Log Analytics, then that it's not quite so simple. This is where Fluent Bit can help.

Azure Kubernetes Service (AKS) Security Features

Today, we are deploying a Kubernetes cluster for our application. Azure Kubernetes Service (AKS) has many advantages over similar Kubernetes platforms because the user does not pay for the master VMS or its maintenance. An Azure subscriber pays only for the worker VMS. However, AKS — out of the box — is not a production-ready product. The following are the steps we need to take before we became almost production-ready.

In this article, we are going to discuss the following topics:
