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 ...

Problem solve thanks to askubuntu.com My Sql Update Problem after Update

Hi
Long time ago I haven't write in my blog.
The reason of this post is the fallowing. Last one I update mysql package. Mysteriously is stop working and getting a very nice error.

My sql stop working. ProblemType: Package DistroRelease: Ubuntu 12.04 Package: mysql-server-5.5 5.5.24-0ubuntu0.12.04.1 ProcVersionSignature: Ubuntu 3.2.0-27.43-generic 3.2.21 Uname: Linux 3.2.0-27-generic x86_64 ApportVersion: 2.0.1-0ubuntu12 AptOrdering: mysql-server-5.5: Install mysql-server-5.5: Configure Architecture: amd64 Date: Sun Aug 12 23:44:04 2012 ErrorMessage: el subproceso instalado el script post-installation devolvió el código de salida de error 1

I report it as a bug. When I check the status, I saw it was a duplicate bug, and still no answer. So I decide to use askubuntu.com.  I have never use askubuntu.com, only staroverflow, but just for searching never asking a question and never answering one question.

So at the end, I got my answer.
The solution goes the fallowing way

sudo apt-get purge mysql-server mysql-client mysql-common mysql-client-5.5 mysql-server-5.5
sudo apt-get autoremove
sudo apt-get autoclean

sudo rm -rf /etc/mysql

sudo apt-get install mysql-server mysql-common mysql-client


It was import to to the autoremove and autoclean, because I was having trouble with mysql package.
Want to read the complete answer.

Probably you will wonder, who cares if you solve a problem in askubuntu.com? Well I am just sharing how useful is the ubuntu community. And how they can help you. Many people prefer to stop using an application after one problem, instead of asking for help. If you are like that, you can give a chance to all the help ubuntu provides.

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...
