Hey folks, Recently, I was trying to level up the observability of my home automation system, and I was inspired by what has been done by Carmelo and Patrick, who had similar experiences for their own needs. TL;DR 1 2 3 git clone https://gitlab.com/z0ph/tower-control.git docker-compose up -d open http://localhost:3000 # admin/admin Going Further :mag_right: Previously, the only graph that I had was the built-in graph from my home automation system, Jeedom, and it was pretty bad (see below). ...

Purpose When your production workloads rely on AWS IAM Managed Policies (don’t do this), you will need to be notified when changes occur behind the scenes. It’s also interesting to monitor new AWS service releases ahead of the announcements to get spoiled. This pet project automates the retrieval (every 4 hours) of new AWS Managed IAM Policies to make it easier to monitor and get alerted when changes occur (by AWS), using the “Watch” feature on GitHub, RSS or a dedicated Twitter Account. ...

Quick post today about cost saving on AWS. As you know, two of my preferred subjects on Public Cloud are Security and FinOps! Recently, AWS introduced a way to reduce AWS bills by up to 70% using Spot instances with the AWS Fargate service. It’s really easy to use.

Using Terraform, you just have to specify capacity_providers and/or default_capacity_provider_strategy on your aws_ecs_cluster resource. ...

qTweet is a dead simple AWS SQS to Twitter serverless speaker :speaker:. Publish message :love_letter: to SQS (FIFO), Lambda function will handle publishing it to Twitter. Automagically. :tada: To be honest, my plan is to automate the tweet of certain information using this queue in multiple side projects. As usual, I’m sharing this with you folks as I was not able to find an equivalent in GitHub / Open source projects. I hope it could be useful to someone else. ...

Canary What? In software testing, a canary (also called a canary test) is a push of programming code changes to a small number of end-users who have not volunteered to test anything. The goal of a canary test is to make sure code changes are transparent and work in a real-world environment. Canary tests, which are often automated, are run after testing in a sandbox environment has been completed. Because the canary is only pushed to a small number of users, its impact is relatively small should the new code prove to be buggy and changes can be reversed quickly. ...
