Cloud Servers

Introduction

In this article, we will compare the similarities and differences of a cloud server vs a physical server. Every business has similar and different approaches in how they operate.

Reading Time: 6 minutes

What is SaltStack?

SaltStack is an open-source infrastructure management platform built on a dynamic communications bus. The main structure of SaltStack contains two main components for work: one Salt Master and several Salt Minions.

How to Configure Multiple Sites with Apache

Reading Time: 2 minutesIf you are hosting more than one site on a server, then you most likely use Apache’s virtual host files to state which domain should be served out. Name based virtual hosts are one of the methods used to resolve site requests. This means that when someone views your site the request will travel to the server, which in turn, will determine which site’s files to serve out based on the domain name. Using this method you’ll be able to host multiple sites on one server with the same IP. In this tutorial, we’ll show you how to set up your virtual host file for each of your domains on an Ubuntu 18.04 server. Continue reading “How to Configure Multiple Sites with Apache”
