System Administration, Week 1: Warming up to EC2
In this short video, we prepare for our first homework assignment and demonstrate how to launch a #NetBSD instance in AWS EC2.

System Administration, Week 1: AWS Aliases
System Administrators are notoriously lazy, and AWS commands a notoriously lengthy to type. In this video, we demonstrate the use of shell aliases and functions to save ourselves some typing whenever we run AWS EC2 commands.
The aliases and shell functions we use are available here:

System Administration, Week 1: Warmup Exercise 1 - No Space Left On Device
In this video, we try to find out what happens when we run out of disk space as well as how the system behaves when use up all inodes. This is intended as a warmup exercise for our week 2 topic, introducing the concept of disk storage and filesystem behavior.
System Administration, Week 2: Storage Models and Disks
In this video, we'll introduce the larger topic of filesystems and storage. In particular, we'll discuss the conceptual storage models, such as Direct Attached Storage (DAS), Network Attached Storage (NAS), Storage Area Networks (SANs), and Cloud Storage.
@jschauma my cheat sheet for this:
DAS: disks in your computer
NAS: disks in your network
SAN: your network of disks
Cloud Storage: disks you don't own
🙂
