What is Service Mesh?

A service mesh is an additional infrastructure layer that provides a means of communication between all services in a given application. It is typically deployed as a series of proxies alongside each service instance. Since the service mesh proxies are deployed alongside the application services and not as part of it, they are often referred to as sidecars. This means that as a whole, these sidecar proxies are a mesh network and an infrastructure layer separate from the application. A service mesh not only brokers communication between all services in an application but, since all requests, both internal and external, pass through it, it provides a means for handling many tasks that can be obfuscated away from the application.

The web-based Kubernetes console is an interface that provides information about the state of the Kubernetes cluster. The dashboard is also used for deploying containerized applications as well as for general cluster resource management. Traditionally, kubectl is primarily used in the terminal for nearly all cluster related tasks. Still, it is useful to have a visual representation of our cluster in a user-friendly interface. To install the dashboard, kubectl needs to be installed and running on the server.

What is Kubernetes?

In this article, we review what Kubernetes and Kubeadm are, how to install, create a cluster, and set up worker nodes using Kubeadm. If you are not yet familiar with Kubernetes, we recommend reading our article on the fundamental basics of Kubernetes.

Introduction

This article will demonstrate how to install and configure Minikube to set up a small Kubernetes cluster. We will then examine Kubernetes in more detail to apply that knowledge to a real-world example.

What is Kubernetes?

Kubernetes (or K8s) is an open-source container orchestration system for automating computer application deployment, scaling, and management. Kubernetes manages and runs Docker containers on numerous hosts. The project was started by Google and is supported by many companies, including Microsoft, RedHat, IBM.

What is K3s?

K3s is a lightweight version of Kubernetes. It is a highly available Kubernetes certified distribution designed for production workloads in unattended, limited resource, remote locations, or inside an IoT appliance. The developers of K3s declare that K3s is capable of almost everything that K8s can do. 

What is Puppet?

Puppet is a cross-platform client-server based application used for configuration management. It handles the software and its configurations on multiple servers. There are two versions available. One is open-source, the other is a commercial version. It works on both Linux and Windows platforms. It uses a declarative approach to automate updates, installations, and other tasks. This feature allows the software to configure those systems using files called manifests. A manifest contains the instructions for a group or type of server(s) being controlled. 

High availability is the description of a system designed to be fault-tolerant, highly dependable, operates continuously without intervention, or having a single point of failure. These systems are highly sought after to increase the availability and uptime required to keep an infrastructure running without issue. The following characteristics define a High Availability system.

Introduction

Ansible is a system of configuration management written in Python programming language which uses a declarative markup language to describe configurations. It’s used for automation of configuration and OS setup. Ansible is often used to manage Linux-nodes, but Windows is also supported. It supports work with devices with Python v2.4 and higher installed through SSH connection. In this article, we are going to review the DevOps tool called Ansible.    

In this tutorial, we will be reviewing what the fundamental similarities and distinctions are between Kubernetes and Docker Swarm. Kubernetes and Docker are two of the major players in container orchestration. Both Kubernetes and Docker Swarm continue to grow in popularity as they are increasingly used by those working with container deployment, orchestration, and management. Across all vertical markets, businesses continue to find new methods of utilization and practice with more uses constantly being discovered.
