Amazon Web Services has done nothing short of disrupting the traditional data center paradigm. Large corporations to small startups are testing, prototyping, and sometimes flat out converting large scale data centers to Amazon Web Servers. Running applications on Amazon Web Services isn't exactly the same as running them in traditional hosting environments. In some ways it feels the same and in others it feels, well, incredibly better. With AWS we can build our applications on top of a scaleable and elastic, fault tolerant infrastructure that helps react automatically to any change in demand for your app. Here is the most common misconception of the cloud, it's not magical. It doesn't just "do everything for you". You still need to build on it, code it, automate it, configure it, network it, and everything else. You just do it differently now. To help prepare organizations and individuals for this process, Amazon recently announced a certificate program called AWS Certified Solutions Architect - Associate Level. I've recently had the opportunity to sit in on this exam and pass it on the first try. Without breaking any NDA's I agreed to while taking the exam, I'm going to attempt to help you "prepare" for the exam. After reading several other posts on the internet, I notice that they are pushing you disproportionately towards services such as VPC (Virtual Private Cloud). Lets see if we can't clear a few things up and help you prepare for this exam.

This is a great opportunity provided by the Linux Academy and for me, especially is beneficial, as my primary role…
I have implemented a new passwd policy and am forcing users to change their password. The problem I'm facing is I don't they dont' know what the password requirements are. How can I communicate this to them before they change their password using passwd? That's a great question, and it's actually really simple. What we have to do is create our own custom script that displays the password requirements and then calls the passwd program. And we have to call the script whenever a user types passwd command at the prompt.
The network tool 'ping' has been used by almost everyone who regularly uses a PC at one point or another. The tool is so ubiquitous that it is installed by default on every modern networkable operating system and has been for some time. It is both simple to use and can be a powerful means of exploring your network locally and the internet at large. We are going to go over some use cases and explain exactly what it is and how it works.

For some of you, this is a basic command that you use literally all the time, If this is you, then this tutorial isn't for you. But if you're new to Linux or just new to the command line "ls" is a command you will get to know very well. At the surface level, ls is a simple command, and if typed in any directory or anywhere on the command line, all it does is list the contents of your current working directory. But if I were to leave it at just that I would have done you no favors at all. In fact, I'm going to tell you some tips and tricks to ls and we might even throw in a grep command if you're lucky!
With the increases in bandwidth available to everyone, rich media services, and available information via the internet, video streaming is going to explode. You might think you see streaming everywhere now, but in realty video streaming is still in its infancy. There are many options for video streaming such as YouTube (yes, they have live streaming), Livestream, Ustream, and I'm sure there are a few others. However, some of those are expensive and others we just don't want to use because of their branding. So what is the solution? Wowza! Seriously, the name is Wowza and we just happen to know a few experts that are going to help teach you to get started streaming with Wowza.
A few years ago I could only dream of being able to take the internet with me wherever I went, affordably that is. Now, not only do we see almost every fast food restaurant, coffee shop, ice cream parlor, and car wash (ok not really car washes) with internet access, but we have the ability to take wireless devices with us to create hot spots. Most of us have phone services that perform this luxury for us, however, with limited data plans, lack of LTE connectivity or grandfathered in data plans our cell phones might not be the ideal tools for wireless hot spots. Here is a list of a few ways (including your cell phone) to take the internet with you wherever you go. You'll never again be without internet access to your laptop.
