RHCSA(18): Your Lab in the Cloud: An Introduction to Linode
Executive Summary
In this episode of the RHCSA Series Podcast, we are building our workshop. We're moving from the blueprints and theory of the first 17 episodes to laying the foundation for all the hands-on work to come in Season 2. This episode is your guide to setting up a professional-grade lab environment in the cloud using Linode.
Think of this as commissioning your personal training ground for the RHCSA exam. We'll start by explaining why a cloud-based lab is the modern, flexible choice for aspiring sysadmins and why Linode is the perfect platform for our needs. We'll demystify the cloud so you can confidently create and manage your own virtual server. By the end of this episode, you'll understand the exact environment we'll be using for the rest of the series and the core concepts you need to get started.
Finally, we'll walk through the essential vocabulary of the cloud, covering everything from "Linodes" and "Images" to "Regions" and "Plans." We'll also take a high-level tour of the Linode Cloud Manager so you know exactly what to expect. Mastering this simple setup is the first practical step on your certification journey. It ensures that when we start diving into complex topics like LVM and SELinux, you'll have a stable, reliable, and easily accessible lab ready to go.
