Today we introduced our first of many troubleshooting Live Labs!™ for our AWS labs. This specific lab is setup to help SysOps practice there VPC and EC2 instance connectivity issues. The lab is build in such a way that “tasks” are needed to be completed in order to resolve the connectivity issues displayed in the lab situation. This lab was added as part of complete training course including over 20 hours of training, videos, practice exams, and labs for the AWS Certified SysOps Administrator – Associate Level exam and our current 80+ hours of AWS Certification Training.
Like our series of ongoing articles on Ubuntu 14.04 LTS, we are starting a series of articles on the recently released CentOS 7 distribution. Unlike Ubuntu, new versions of CentOS take years in between major versions. CentOS also supports their major releases for quite some time (see the table below). This first post will introduce some of the major changes to CentOS at a high level and then over the next month or so, we will discuss many of these changes in more detail. Let’s get started!
CentOS Support Timeline
Just as a quick overview, let’s take a look at the support life of each of the last major releases of CentOS (in general, seven years from release date):
- CentOS 5.x – End of Life 03/31/2017
- CentOS 6.x – End of Life 11/30/2020
- CentOS 7.x – End of Life 06/30/2024

In this show we are going to talk about how best to prepare for the AWS certifications. We take A LOT of questions from the community in live chat and answer them as we move along.
One of the newest things added to CentOS 7 is the capability to do an in place upgrade of CentOS 6.x to CentOS 7. In the past, the only official method of upgrading major versions of CentOS was to wipe and reinstall everything. Having said that, there were always processes you could follow with varying levels of success (based on straying from the official repositories and how customized your setup and package list was). We have run through this process now about a half dozen times, with varying levels of success, so let’s talk about some of the successes and failures.
A few days ago Amazon announced that they were to release there new application stack called Zocalo. Zocalo is a cloud based document sharing and collaboration tool. Zocalo is very similar to the features that are provided by DropBox however have a much more mature enterprise integration. In fact you can integrate users and there permissions using your existing Active Directory environments. Using the zocalo service you are able to setup what is called a zocalo site. Zocalo sites are hierarchies that you use to share both internally with your organization as well as externally across organizations. You can access your files using any device such as iPhones, androids, and kindle fire’s.
Here at the Linux Academy we are already taking full advantage of this new service to collaborate and and check-in things like new lab guides. We can easily comment on our lab guide to the original owner of the document so that they can receive feedback right within the zocalo portal. You can see revisions and versions of each uploaded file as well so you have a fully managed progression when working with new publications etc.
Today I am very excited to announce we already have three video lessons that walk you through setting up your first Zacolo site as part of the Hybrid AWS Technologies course at LinuxAcademy.com. The first overview video is actually available publicly. The rest of the Zacolo videos walk us through using it and collaborating with teams. And in the near future I will even release a lesson on integrating user access via Active Directory.
We are happy to announce the immediate availability of our newest AWS self-paced and hands-on Live Lab!™, Resizing Or Changing A Root EBS Volume.
This lab is a standalone lab which means you can take it without it being part of a course. It was created to go along with our AWS Certified SysOps – Associate Level certification prep course. While we were learning about monitoring and performance metrics as they relate to AWS and more specifically EBS we thought it would be helpful to learn how to change EBS volume type from SSD to Provisioned IOPs and/or increase the partition size which also increases the base rate IOPs for your volume.
The lab is one hour long and can be completed in as little as 15 minutes! Not only is the lab guide available for download for your own personal notes and future reference, we also provide a video for the Live Lab!™ in the AWS Certified SysOps – Associate Level course.
We had our first Live Show for LinuxAcademy.com members. We are very excited to make available our first live event recording! In this show we announce new content, features, and meet the instructors at the Linux Academy!
Congratulations! You are here because you landed an interview where Linux is either a key part or the entire focus of your prospective position. In this article, we are going to cover both practical (general interview) and technical topics that you can use to help you be prepared for that discussion.
We won’t spend a lot of time on general interview preparation, but it won’t hurt to go over a quick list of items to consider, bring or have prepared:
- Notepad and Pen – this servers a couple of purposes. It will give you something to do with your hands (we all get nervous) and it will help you focus on the conversation, you can write down key points, items you have questions on or want to circle back to as well as things that you need to follow up on later
- Dress Appropriately – many technical jobs have a more casual dress standard, however, you don’t have the job yet. Particularly if you have not asked, shirt, slacks and tie are minimum, a suit (male or female) preferred.
- Research – do a little research on the company. There is a wealth of material available on most company websites, be sure to look them up. At the end of the interview when you are asked if you have any questions for them (standard end question), you can have one or two prepared that let them know you took the time to learn about what they do.
- Be Early – sometimes it is not enough to be on time. Many times an interview will start with you needing to complete a formal application when you arrive. Get there 20 minutes early so you can get paperwork out of the way and start the conversation on time. Being respectful of their time is a key indicator of how you will be as an employee.
