Boot Loaders

What happens when you turn on a computer system? At the most basic level, we know that the computer’s components power on, and the operating system “boots up” so users have a way of interacting with the systems – whether that is to play games, run a web server, set up in-depth applications or otherwise. But how does a computer know what to boot? If a processor pulls data from the system’s memory, how can it work with a freshly booted computer that does not have any processes within its memory stores? For this, the computer uses a boot loader, which is a small amount of code designed to prepare the system and then pass it to the more complex kernel, which in turn manages the operating system itself.

Linux Academy: A Visual Course Guide

Students come to Linux Academy from all across the globe, each with varying skill sets and experience levels. Some students know exactly the course (or courses) they want to take, while others are looking for guidance or a starting point. Navigating the certification/e-learning landscape can be confusing, with many different courses and content from which to choose.  Have you ever asked yourself one (or more) of the following questions?

  • Where do I start?
  • What course is right for me?
  • What course should I take next?
  • What “path” is best?
  • What course should I take first, as a prerequisite?
  • I don’t need a to get a certification, what other types of courses do you offer to learn new skills?

To help answer those questions, I present to you the Linux Academy Visual Course Guide. (more…)

RAID Explained

RAID, or a redundant array of independent disks, is a storage solution intended to improve some combination of fault tolerance, storage management, and performance. RAID works as a form of storage virtualization that combines multiple physical disks into one logical volume.

RAID works by saving data in either a mirrored or striped manner (sometimes both), with or without parity. How the RAID is set up is noted through RAID levels. (more…)

What is Fault Tolerance?

Scalability, high availability, containers, fault tolerance and eventual consistency. Tech terms can be confusing to those new to server administration or development. In the coming weeks, we’ll be breaking down common — yet potentially confusing — terms you will undoubtedly come across in your learning journey.

toleranceOne of the primary themes of this series — and a keystone part of working as a systems administrator, engineer, or developer — is not just getting servers to run, but keeping them running. While we’ve already address scalability, high availability, and eventual consistency, another piece of the puzzle is not just avoiding failure, but how to gracefully navigate and plan for any potential failures in the future. For this, we plan out fault tolerant systems. (more…)
