Salt, or SaltStack, is a remote execution tool and configuration management system. Its remote execution capabilities allow administrators to run commands on various machines in parallel with a flexible targeting system. In this guide, we will discuss some of the basic concepts and terminology needed to begin learning Salt.
This tutorial will walk you through the process of creating an automated server provisioning using Ansible, a configuration management tool that provides a complete automation framework and orchestration capabilities. We will focus on the language terminology, syntax and features necessary for creating a simplified example to fully automate the deployment of an Ubuntu 18.04 web server using Apache.

Envoy is an open source service proxy designed for cloud-native applications. In Kubernetes, Ambassador can be used to install and manage Envoy configuration. Ambassador supports zero downtime configuration changes and integration with other features like authentication, service discovery, and services meshes.
Ansible is a modern configuration management tool that facilitates the task of setting up and maintaining remote servers. With a minimalist design intended to get users up and running quickly, it allows you to control one to hundreds of systems from a central location. This short guide demonstrates how to execute Ansible playbooks to automate server setup, using an example playbook that sets up an Nginx server with a single static HTML page.
Configuration management systems are designed to make controlling large numbers of servers easy for administrators and operations teams. They allow you to control many different systems in an automated way from one central location. In this guide, we will discuss how to install Ansible on an Ubuntu 18.04 machine and go over some basics of how to use the software.
In this tutorial, we will cover how to install open source Puppet 4 in a master-agent setup on CentOS 7. In this setup, the Puppet master server—which runs the Puppet Server software—can be used to control all your other servers, or Puppet agent nodes. Note that we’ll be using the Puppet Server package, instead of Passenger or any other runtime environment.
In this guide, we’ll demonstrate how to create Ansible inventory files and organize servers into groups and subgroups, how to set up host variables, and how to use patterns to control the execution of Ansible commands and playbooks per host and per group.
Ansible and Terraform are not competing solutions, as they resolve different phases of infrastructure and software deployment. In this tutorial, you’ll deploy Droplets using Terraform, and then immediately after their creation, you’ll bootstrap the Droplets using Ansible.
In this article, we define Infrastructure as Code (IaC) and explain the benefits of IaC in development and deployment workflows. We also start to learn about Terraform’s role in the IaC workflow and understand “what is ‘state’?” in IaC.
