Modern Architecture for Native Apps with AWS Backend: A Practical Guide

Introduction Designing a mobile app today goes far beyond building a beautiful interface. Native apps — whether for iOS or Android — need secure authentication, user role management, real-time communication with the backend, and scalable infrastructure to support growth. In this post, I’ll walk you through a clean and modern architecture to connect native mobile apps to a robust backend on AWS. The architecture is modular, scalable, and aligned with best practices for security and performance — without relying on overly complex tools. Why it matters: apps today are more than just UI A production-grade mobile app often includes: User login (email, Google, or others), Differentiated access for multiple roles (e.g., user vs admin), Secure token-based communication, A backend capable of handling business logic and data, Data storage, asset management, and scalable APIs, Compliance with Google Play and App Store requirements. All of these require a backend architecture ...

Adding Users to Existing Groups in Ubuntu (Oneiric Ocelot)

Hi have been working in Virtual Box, this days and need to add my user to the vboxusers group. I was going to do it graphically, and suddenly I notice that the application I use for doing this job it disappear. :(
So I have to use the CLI

If you know the group just do this
Steps
  • sudo usermod -a -G GROUP USER
    where -a means append. Add the user to the supplementary group(s). Use only with the -G option. If you want to read more about the usermod do
  • man usermod

If you don't know the group
Steps
  • groupmode 2 TIMES
  • sudo usermod -a -G GROUP USER
    If you see the only difference is that you type groupmode and press tab 2 times and all the groups will be display.


HOPE it works

Understanding Liveness, Readiness and Startup Probes in Kubernetes

 This is a small article about understanding the liveness, readiness and startup in kubernetes.  There's good explanation in the kubernetes documentation: https://kubernetes.io/docs/tasks/configure-pod-container/configure-liveness-readiness-startup-probes/ This video also explains well the process: https://www.youtube.com/watch?v=aTlQBofihJQ But I wanted to understand it in a practical way. So I have this demo: https://github.com/DiegoTc/guest-book-js-docker/tree/Running-App-Version-1 It's a simple application running on a kubernetes cluster. https://github.com/DiegoTc/guest-book-js-docker/blob/Running-App-Version-1/argo/deployment.yaml apiVersion: apps/v1 kind: Deployment metadata: name: chat-ui spec: replicas: 1 revisionHistoryLimit: 3 selector: matchLabels: app: chat-ui template: metadata: labels: app: chat-ui spec: containers: - image: diegotc/guestbook:20230803-064434 imagePullPolicy: Alwa...

Getting Docker Syntax In Gedit

I have been working with docker in the last days, and encounter the syntax issue with gedit. Just pure plain text. So make a small search and found an easy way for fixing this. I found Jasper J.F. van den Bosch repository in GitHub and found the solution for this simple problem. We need to download the docker.lang file, available here:  https://github.com/ilogue/docker.lang/blob/master/docker.lang After that, you go to the folder you save the file and do the following command. sudo mv docker.lang /usr/share/gtksourceview-3.0/language-specs/  If this doesn't work you can try the following: sudo mv docker.lang  ~/.local/share/gtksourceview-3.0/language-specs/ And that's all!

Ansible using plugins for dynamic inventories

This is a small post about how to use inventory plugins in Ansible. If you are looking the script way I recommend to read this article: http://gloriasilveira.com/setting-up-ansible-for-aws-with-dynamic-inventory-ec2.html It explains really good this or you can watch this video: https://www.youtube.com/watch?v=LnbqO1kTPqE&t=6s But if you’re looking to use inventory this article can help you. First of all, why should I used inventory if all over the internet they’re using the python scripts? Well, Ansible recommends it: Inventory plugins take advantage of the most recent updates to Ansible’s core code. We recommend plugins over scripts for dynamic inventory. You can write your own plugin to connect to additional dynamic inventory sources. https://docs.ansible.com/ansible/latest/user_guide/intro_dynamic_inventory.html The actual ansible guide is quite good, but there was a step that got me confused, probably my english isn’t so good and I didn’t understood it. We need to ena...
