CompTIA Cloud Essentials

Cloud Essentials is a basic certification through CompTIA. The certification aims to provide a vendor-neutral, conceptual understanding of the cloud. Cloud Essentials focuses on real-world issues and practical solutions for cloud computing, as it relates to business and IT. This is not a technical-heavy course and centers on the principles of the cloud, instead of the command line. CompTIA also has a CompTIA Cloud+ certification more in the direction of technical-heavy concepts that Linux Academy will offer in the future as well. If your organization uses the cloud or is still on the fence of migrating services into the cloud, the Cloud Essentials is a great starting point for you. (more…)

What is Big Data?: The Three Vs

Data is powerful: Used right, companies, scientists, research institutions, or even the average person can make informed choices based on data discoveries. With enough information parsed through the right tools, medical professionals can track trends in the spread of illnesses, companies can predict customer needs and wants, or environmental scientists can discover new correlations between human actions and environmental effects — the possibilities may well be endless.

However, to achieve these goals, the data sets processed need to contain a vast amount of data — not just terabytes of information, but peta- or exabytes; the sort of data that is usually too unwieldy for traditional relational databases and data processing systems to handle.

It is just not a matter of databases, either: When handling massive amounts of information, concerns are not limited to the storage of it but also its analysis, visualization, searching, sharing, and more. These issues are condensed into the “Three Vs” of managing big data: Volume, velocity, and variety. (more…)

Use the Azure CLI from Linux, Mac or Windows

If you’ve been following the growth and culture changes at Microsoft lately (and we have), you’ve probably noticed a different Microsoft emerging under the new leadership. With that has come an increase in company openness and a set of tools that “play nice” with other platforms. We’ve seen the emergence of “Linux Bash on Windows,” a cross-platform, free, code editor (Visual Studio Code), the open sourcing of .NET, C# language compilers, and ASP.NET and a massive shift toward “coding in the open” on GitHub/Microsoft. Another example is the cross-platform Azure CLI (Command Line Interface).

Azure Essentials

Linux Academy introduces Microsoft Azure Essentials

This week we released the first course for our Microsoft Azure cloud training. This is an introductory course for learning about the basic concepts of Microsoft Azure, what it can do for us and how to get started. This course is the first of what we hope to be many Azure training courses, due to popular demand from our users.

So what is Azure anyway? Azure is a cloud computing platform and infrastructure created by Microsoft for building, deploying, and managing applications and services through a global network of Microsoft-managed data centers. Simply put, if you are familiar with Amazon Web Services, Azure is Microsoft’s cloud services offering. Depending on your business needs, for a public cloud or hybrid cloud, there are many reasons your organization may be using one over the other. (And as a fun side note: You can absolutely run your Linux application workloads and Linux distributions within Azure too!) (more…)

Preparing to Take the Certified OpenStack Administrator Exam

OpenStack Summit 2016 Austin

This past week at the OpenStack Summit in Austin Texas I had the privilege of speaking about what it takes to prepare for the OpenStack Foundation’s new Certified OpenStack Administrator exam. I wanted to share with the audience, and now with you, some of the primary steps you need to focus on when becoming a certified professional for administrating OpenStack environments. (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…)

Introducing Practice Exams v2.0!

We’d like to take the time to announce an exciting new feature that is now available on LinuxAcademy.com!

Our goal is to help you pass exams and get certified for your career.  We are very proud of our courses, and have recently made a significant upgrade to the way Practice Exams work.  Not only are practice exams a great way to study, but also it teaches you how to manage your time in an exam.

When you start a new practice exam, you will have the option to take a regular exam, or to enable Practice Mode.

SS1 SS2

Regular Mode loads in a pre-set number of questions and a pre-set amount of time for you to take the exam. For example, if you’re taking AWS CSA Associate in Regular Mode, it will load 60 questions and give you 80 minutes to complete the exam, just like a real exam. These questions are random questions, the potential answers are randomized each time, and each time you run the practice exam it will randomly pull from the potential pool of questions. In order for the practice exam to be checked off of your syllabus towards your certificate of completion, you must complete the exam successfully in regular mode.

But, what if you are short on time? What if you want to answer more questions in a shorter duration? Or, do you want less questions but a longer amount of time? It doesn’t matter, you can have all! In Practice Mode, you to select your time limit and the number of questions (up to the maximum amount in the potential pool) and then take the practice exam. This helps you prepare in any different way you want for the exam, and it puts flexibility into the practice exam system based on your current needs.

SS2

Remember, you have to use Regular Mode to complete the practice exam from the syllabus. In other words, you can’t enable Practice Mode, select 2 questions and 1 hour time and it count towards your Certificate of Completion.

Here is a summary of the new features available on the practice exam system:
1. Will display the total number of questions in your exam session
2. All practice exams are now timed. If time runs out, it will automatically submit the questions you currently have for grading.
3. Practice Mode allows you to define the number of questions and time limit for an exam session
4. Question order is randomized each time a new practice exam is started
5. Answers associated with a question are also randomized each time a new practice exam is started

Please note we are still loading pre-sets for some practice exams. If a pre-set is not currently available, it will default to the max questions and max time.

OpenVPN, OpenSwan, and AWS VPC

The last week or so I have been working on the content of Linux Academy’s new Hybrid AWS Technologies course.  Going through the OpenVPN and OpenSwan lessons I thought it to be the perfect opportunity to talk a little bit about how awesome these open source VPN solutions are.

If you’ve gone through any of our AWS courses at the Linux Academy you probably already know that Amazon VPC has built-in functionality that you can use to utilize in order to connect your on-premise network to your VPC instances on the Amazon cloud. But if you’re a business that already uses OpenVPN or an OpenSwan VPN server at your on-premise networks then today I want to talk a little bit about connecting those two environments.
