This document discusses Creatia's infrastructure technologies, specifically their use of Amazon ECS Fargate. It provides an overview of:
1. Why they chose Docker and ECS Fargate over other options like Kubernetes due to lower learning curve for their engineers who were new to containers.
2. Their application architecture which uses Ruby on Rails for the backend API and Nuxt.js for the frontend SSR rendering.
3. The challenges of setting up ECS Fargate as it was their first project using containers in production, and resources they found helpful for learning AWS services needed to support it.

?
Security requirements for IoT devices are becoming more defined, as seen with the EU Cyber Resilience Act and Japan’s JC-STAR.
It's common for IoT devices to run Linux as their operating system. However, adopting general-purpose Linux distributions like Ubuntu or Debian, or Yocto-based Linux, presents certain difficulties. This article outlines those difficulties.
It also, it highlights the security benefits of using a Linux-based container OS and explains how to adopt it with JC-STAR, using the "Armadillo Base OS" as an example.
