You can now have access to all our video courses, flash cards, and community features free for 7 days when you sign up for a Linux Academy account. Here’s just a few of the features you can start using: (more…)
A few months ago, I had an idea for a mobile app that would be cool and useful. I had no delusions of hitting it big in the Apple or Android app — it was just a fun side project for myself. I had never built a mobile app before, and owning a Galaxy Note 4, I saw a great opportunity to teach myself Android Studio and build an Android app. So I downloaded Android Studio, got it all setup, and watched some online tutorials to learn the basics. I then mapped out what I needed for my app, and this is when the feeling of dread set in. For my app to work, I needed: (more…)
We are happy to announce the beta release of our new feature, Study Groups! With Study Groups, you can create a private study group and invite other Linux Academy students to join, or create a public study group where anyone can join.
Today we announce our new education membership pricing packages for current university-level students and professors who wish to supplement classroom learning with hands-on training.
Linux Academy now offers a 3-month membership for only $60 to any current college or university students looking to enhance their IT education. In addition, university-level professors are eligible for a free membership to supplement their curriculum with Linux Academy’s resources for Linux, AWS, OpenStack, DevOps, Azure and Big Data (coming soon).

IAM policies are imperative when setting up permissions for your Amazon Web Services resources. Whether you are a one-person shop or part of a large organization, understanding how they work and how to set them up is crucial. If you don’t set up IAM policies properly, you will create security holes or you won’t have the correct permissions for your users. (more…)
Those who have used CodePipeline, know the benefits of the service and how easy it can be to setup and run a pipeline. For those new to CodePipeline, it is AWS’s take on a continuous delivery service. It provides the tools to model, visualize, and automate the software release process.
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.
Closely related to a system’s uptime and functionality is the concept of high availability. A highly available system ensures above-average availability for the users who are accessing your website, application or program.
Key points of high availability for a system are locating and removing all single points of failure, preventing data loss, and ensuring operational stability at peak times. This is primarily achieved through redundancy. (more…)
As some of you may have noticed, we recently released the AWS Lambda Deep Dive course. In this course, we delve into the world of serverless architecture and focus on code instead of infrastructure.
Following the Linux Academy philosophy of learning, the course includes hands-on lectures, downloadable real-world use cases, andLive! Labs.
This course also includes quizzes. Quiz questions break down important concepts to know when it comes to Lambda and tests your understanding of these concepts. Quizzes, when bundled with other methods, are an excellent way to find weak points in your study. Instead of waiting until you go through the entire course before being tested on the material, we’ve included quiz questions at the end of each section. That way, after completing a section, you can see if there are any concepts or topics that you did not quite understand; and if that is the case, you can go back through the relevant videos until it clicks. Of course, if it still doesn’t make sense after that, you can always ask in the community or contact instructors.
How Do Quizzes Work?
If you’ve never taken a quiz on Linux Academy’s engine, you may be wondering what it is like.
