This part of the challenge will cover the setup of the infrastructure at AWS with Terraform, and since I’m a fan of Python I will use/learn FastAPI for web front server effect, plus a picture embedded in the served web page will come from a secured S3 bucket. All of this was part of this great training course Networking in Public Cloud Deployments. We will create all the basic infrastructure from your PC just to follow the training course and gain the fundamental knowledge that we will need for what is to come. ...

I found my next challenge while I was defining the Lab exercises for Networking in Public Cloud Deployments training course. Honestly, I didn’t know much about what was ahead, but I had a great learning idea and the will to go through the challenge. I’m not saying that this is correct nor complete, is my first run exploring the whole thing, so I’m just saying “hey! I can do this!, and this is the Proof of Concept. ...

In the previous post we set up the infrastructure at AWS and we stored the states at GitLab. Now let’s go for the most fun part, integrate everything. We will modify a security group to allow HTTP access to the FastAPI app, and we will have all kinds of notifications and requests for approvals sent to Slack. Every step will be logged and stored in the form of messages in Slack and in a DevOps fashion at GitLab: terraform states, artifacts (which are specifics output that you want to store), logs for each run of the pipeline, etc. This will give you incredible traceability of your IaC. ...

In my previous post, I showed you how easy it is to have a network configuration backup with a GUI and messaging and keep it synchronized with GitHub to see the changes, and also sending messages to Slack and emails when it runs. For this post, I modified the scripts to use a cool Open Source tool named Gogs (Thanks Nikolay Ryzhkov for bringing this tool to my attention). With Gogs you will have a local repository system with the same functionalities as GitHub, so you don’t need to worry about sending your configs outside of your own infrastructure. ...

Continuing with the development of my previous post where we made a very simple and complete solution for local network device configuration backups, including alerts via Slack or email. Now we are going to do some modifications to have a free complete GUI and messaging for Cloud Network configuration backups including the history, comments, and actionable buttons. In the end you will be a simple click away to a full online historic track of all the configuration changes, including comments per line of changed code. Take a look at this short video! ...
