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:

Managed Kubernetes Comparison: EKS vs GKE

Kubernetes is changing the tech space as it becomes increasingly prominent across various industries and environments. Kubernetes can now be found in on-premise data centers, cloud environments, edge solutions, and even space.

As a container orchestration system, Kubernetes automatically manages the availability and scalability of your containerized applications. Its architecture consists of various planes that make up what is known as a cluster. This cluster can be implemented (or deployed) in multiple ways, including adopting a CNCF-certified hosted or managed Kubernetes cluster.

Distributed SQL Change Management With Liquibase and YugabyteDB on GKE

Liquibase is an open source and extensible change management project that supports a variety of databases including Snowflake, MySQL, and PostgreSQL via JDBC. Liquibase allows users to easily define changes in SQL, XML, JSON, and YAML. These changes are then managed in a version control system so the changes can be documented, ordered, and standardized. For more information on the features and benefits of Liquibase, check out their documentation site.

In this blog post we’ll show you how to:

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:

Graylog With Kubernetes in GKE

We all know that when collecting data from different data sources — whether it is an application, server, or service —  it is a necessity to have a tracking system that tells what went wrong with your system at a specific time, and to know exactly how your system behaves. 

This article aims to demonstrate how to deploy The Graylog Stack — Graylog v3 and Elasticsearch v6, along with MongoDB v3 — use Kubernetes, and how to collect data from different data sources using inputs, and streams.
