What are Containers?

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.

containersWith the advent of platforms such as Docker, containers are an oft-spoken term in system administration and programming. But what are containers? At a base level, someone new to containers might understand they “contain” an application, but how does it work? What are the benefits and use-cases? (more…)

Cloud Security – What You May Not Know Might Hurt You

If you use a cloud provider for your application and infrastructure needs, tell me quickly: Where is your data? Don’t feel bad if you really don’t know, most people and organizations have no idea where their data actually resides.

Security Conversations

There are security implications the moment you move your data off site and use any outside hosting or cloud provider. How do you protect it from malicious attempts to access? In many cases, your efforts at securing that data may be falling victim to the security conversations that are not happening.

Where is it? Physically, where does it reside? That sounds like a loaded question because we all know, in the cloud, it could be anywhere at any time. However, in the case of sensitive corporate or personal data, that could be a problem, right? At any given point in time, the data for your application and the customers that use it is physically somewhere in a data center on one or more physical disks of some kind. A quick look at AWS, for example, provides information about the Availability Zone and Region that an application and its data is in, but nothing specific as to location. (more…)

Cloud Cadet Episode 8: Student Interview About AWS Certifications

Today’s episode is hosted by Anthony James, founder of Linux Academy, and by AWS instructor and co-host, Christophe Limpalair. In this edition, we are joined by Thomas, a student based in Portland, Oregon, who has gone through and absolutely nailed the various AWS certifications through the use of Linux Academy.

Thomas has spent the last few months truly diving in AWS to brush up on his technical chops and learn how to be more technologically independent. He is been on the forefront of new technology for a while now, with his involvement in virtual reality, but with everyone migrating to cloud computing, he explains his thoughts about why AWS will be a big opportunity for growth shortly.

Thomas’s interest in AWS was sparked by wanting to what the forefront of hardware entailed, and by his desire to truly understand how the internet and the cloud work. He felt led to learn about AWS and discover more about its inner workings, which is what brought him to us at Linux Academy.

Today’s topics include:

  • Thomas’s involvement in the development of an OculusRift game
  • The best points to memorize to ace your certification
  • Why he powered through the exams as fast as possible
  • The importance of paying attention to detail
  • How to know when you’re ready to move on from a topic
  • Tips to getting through the exam effectively and efficiently
  • Thomas’s experience interacting with the LinuxAcademy community
  • Being inspired by other people’s success
  • His study process and how he prepares the night before

Thomas currently holds four certifications, has completed five of the courses and passed all three associate level certifications – all in about 10 weeks time. It is safe to say his study methods are Linux Academy approved, as well.

That being said, our focus today is finding out the best tips and tricks that Thomas applied while preparing for his AWS certifications and exams. Not only will you discover one of the best techniques to solidify the information you’ve learned, but he gives expert advice about the most effective way to begin your exam, and much more!

Take advantage of the resources we have at Linux Academy so you can be prepared, too! Also, be sure to check out Christophe’s podcast, Scale Your Code. Thank you for tuning in to another edition of Cloud Cadet!

Linux Academy Flash Cards

Are you studying for an exam and need a quick way to remind yourself of the essentials?

Are you a furious note-taker that loves to organize?

Do you prefer to quiz yourself with your own words because you know that writing questions is a great way to learn and understand?

Introducing Linux Academy Flash Cards!

We’ve expanded the Notes function of Linux Academy significantly. Each course will now feature the Create Deck option for convenient note-taking and studying.


Once you create a deck, you can begin making flash cards. These flash cards will “live” within a course and act as your notes. However, notes are now double-sided, so that instead of having just the note itself, you have a way to quiz yourself in a manner that works for you. (more…)

Cloud Cadet Episode 7: Serverless Architecture in action with Sander Nagtegaal Co-Founder of Teletext.io

“We learned from previous startups… Because even as Teletext became a company, we learned from experience that one of the most important things if you launch a product that you’re still testing and not making money with, is for it to be cheap. If it’s cheap, you have a much longer runway and you can keep up with the competition much longer. The quickest way to let your startup fail is to spend too much money, too soon.” – Sander Nagtegaal, CTO at myTomorrows, co-founder of Teletext.io and Peecho

Welcome to episode seven of Cloud Cadet! Hosted by Anthony James, founder of Linux Academy, and Linux Academy instructor Christophe Limpalair, this episode features an interview with guest, Sander Nagtegaal. (more…)
