Virtualization for Embedded Systems Series: Containers Deep Dive

November 18, 2019

In the previous post, I looked at several real-world use cases for containers and hypervisors. This post will be a deep dive into containers and a how-to on using them. Note: all the code, Dockerfiles, etc. are archived in a git repo at GitHub. Container History Origins A little history is needed before we jump into building and deploying containers. Docker, which is likely still the largest container technology provider by a longshot, was originally released in 2013. In just…

Series, Virtualization

In the last post, we looked at several different types of virtualization technologies. We wrapped up by narrowing our focus on the types of virtualization down to just two primary categories – hypervisors and containers. In this post I’ll dig in to some real world applications of these types of virtualization, and we’ll look at how they can be used to solve real problems. Containerization Simplified Management One of the low hanging fruits of container virtualization is the ability to…

Multicore processors were first introduced in the early 2000’s, and were pervasive in common computing platforms by the 2010’s. The industry started with dual core chips, and then quad core, and now we are up to 48 cores! When the hardware industry brought multicore chips to fruition, the software community had to invent new ways to utilize those additional cores. I’d like to use this post to discuss a few of the common multicore software utilization schemes or modes and…

The concept of computing has been around almost as long as the mathematics from which it derives its usefulness. The world of computing as we know it today only began in the last century or so, and really only since the invention of the bipolar transistor. Fast-forward to the modern era of computing wherein we have unfathomable computing power surrounding us daily. Computing platforms and the related technology is driving advancement in every industry across the globe. From research to…
