Announcing Fullstack Serverless Applications on AWS

Announcing Fullstack Serverless Applications on AWS

I’m excited to announce that my Fullstack Serverless Applications on AWS course is now live on Linux Academy. People who enroll in this course can expect to review some basic concepts related to serverless applications before diving into six hands-on labs, a bunch of supplementary videos, and several quizzes that will help give context and solidify your understanding of how and why we might build a serverless application. In the course, you’ll be making a serverless application for Prometheon Music to use to help manage their music rating system.

A New Method of AWS Training

A New Method of AWS Training

Prologue A few years ago, I knew nothing of the cloud – I wasn’t even working in a traditional IT job.  Throughout my 20s, I was always more of a business guy; however, in my early 30s, I started to see the handwriting on the wall: Tech, and tech jobs, were the future.  And although my work experience to this point was on the business side, I grew up with a solid foundation in tech. Back in the early 90s, I was the first in my neighborhood to get online – name any early 90’s online platform (pre-AOL), and I had an account.  I ran a side business in high school upgrading computers with more RAM, hard disk space, and modems.  I also completed a few programing classes in high school (Pascal) and college (C).  I knew computers, and I knew tech, but I left that all behind as I progressed through college. Fast-forward to eight years later, and I found myself being pulled back.  In the late 2000s, I started to notice all these inefficiencies in the company I was working for at the time. We lacked proper data analytics, and there were numerous workflows that could be automated in various departments. I began spending evening and weekends writing up ideas for various software applications we could build to help solve these issues.  Before I knew it, the company had an in-house development team building many of my ideas. Some worked very well and were very profitable for the company; others were not.  In the end, it reignited my love for tech, programming, gadgets, hardware, and software. Around 2013, I left that company in search of a new career.

Troubleshooting EC2 Connectivity Issues

Troubleshooting EC2 Connectivity Issues

Learning AWS can be a very long and daunting experience. There are dozens of primary services, each with hundreds of features to learn. However, very few things can be more frustrating than having connectivity issue when trying to access a provisioned AWS resource, like an EC2 instance.  After all, you just spent hours learning about AMIs, instance types, IP addresses, user-data, storage volumes, security groups, and key pairs.  Now you just want to actually access the damn instance and have some fun with it. But as you try to access the instance, whether by SSH or HTTP, you get one of these dreaded errors: “access denied,” or “operation timed out,” or some other variation.  Regardless of the error - you can’t log-in. AAAAARRRGGGGGG! Ok, so you vent a little bit – perhaps even yell at your computer.  Regardless of your frustration, you still need to figure out what is wrong.  With that in mind, I present some of the common (perhaps even simple) issues that cause many connectivity issues.
