An automation journey
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 …
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 …
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 …
In the previous post, I oversimplified the situation just for an easy onboarding to the case. Now it’s time to go into deeper details. First I will describe a bit more the design I had for this case, with my context and constraints, and then a great option to add dynamic routing (based on some …
Not so long ago a customer asked me for help on how to block IP addresses on their regional firewalls infrastructure.

Finally, I got my expert subscription to ipspace.net, and enrolled in one of the full courses. After a couple of weeks, I have to say that I’m really impressed with the quality, content, and structure. It’s my best career investment in a long time. It feels like a master degree in networking, why? – content …
Introduction A couple of months ago I was tasked to accelerate a cloud migration from the networking perspective. Context: Cisco ACI already deployed, with security rules grouped by functions and already agreed with the security team Migration to Oracle Cloud (aka OCI) already started and growing But, since Cisco ACI and Oracle OCI are configured …
Even if you don’t fully understand what is an API, it is really easy to leverage their power to have some useful information directly sent to a collaboration platform and receive it on your mobile or PC in real-time. All the tools in use are Free: Python, Slack, and WebEx Teams. In this post, I …
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 …
