Configure Spotify’s backstage with Keycloak OiDC as Auth Provider

Published by Carlos Rodrigues on January 21, 2025

Spotify’s backstage is a widely used developer portal framework. When properly configured, it is very powerful and integrates with dozens of other tools that are used daily by developers, managers and devops teams.

One of the first aspects to consider when setting up backstage is the user access and authentication. Although Backstage provides a few out-of-the-box identity provider integrations, Keycloak is not one of them, and the process to configure it can be a bit daunting, especially if one is new to Backstage and how it is structure.

This article aims to provide a step-by-step guide on how to create a Keycloak OiDC client and how to configure Backstage to use it.

Setting up a secure Mosquitto MQTT Broker with SSL/TLS and User Access Control– MQTT series #2

Published by Carlos Rodrigues on December 21, 2023

Hi and welcome back to the MQTT series, where we’ll go from the protocol basics, to real-world implementations of different use cases, using different brokers and clients. In this article we’ll see how to setup secure a Mosquitto MQTT Broker with TLS and Access Control.

In the previous article we’ve covered the protocol basics, saw how it compares to HTTP and why it is so relevant for IoT.

Today we’ll explore one of most used brokers: Eclispe Mosquitto. We’ll discuss the role of a broker in a MQTT-based architecture and while covering some advantages and disadvantages of Mosquitto, which should help you understand if this is the suitable broker for your use case.
