Quick interlude to my last blog. As part of my last blog on low-risk monolith to microservice architecture, I made this statement about microservices and not doing them:
“Microservices architecture is not appropriate all the time”.
I’ve had some interesting reactions. Some of it along the lines of “how dare you”. I also poked at that a bit on Twitter a month or so ago

I had the pleasure to present “Eclipse Vert.x for Dj fun and for profit!” at the latest edition of the Jug Summer Camp in La Rochelle, France.
The Jug Summer Camp is a popular developer conference organized by Serli in western France, gathering regional attendees as well as speakers and participants from other French Java user groups.

In this post, I will provide a walk through of how to set up Identity Brokering on an RH-SSO server.
Red Hat Single Sign-On (RH-SSO) provides Web single sign-on and identity federation based on SAML 2.0, OpenID Connect and OAuth 2.0 specifications.
For this tutorial, you will need:
- An RH-SSO Instance.
- A Web/Mobile Application with an OpenID Connect adapter.
- An OpenID Connect Provider Server (Such as Keycloak) to be used as the 3rd Party Identity Provider.

Over at the Openshift and Che land, we deal with YAML files for deploying our applications regularly. Unfortunately, the tooling to support editing of these files was not up to our expectations. As we are also tooling developers, we have decided to take matters at hand and implement a language server for kubernetes syntax. An effort which mostly Josh Pinkney and I have worked on for the last few months. As we have progressed with our implementation, we have realized that limiting the extension to kubernetes was wasted opportunity and we have reorganized the language server for general YAML support but kept the kubernetes syntax support built-in.

Software Collections (SCL) give you the power to build, install, and use multiple versions of software on the same system, without affecting system-wide installed packages. Therefore, the Software Collections packaging technique is used a lot for building stacks for Red Hat Enterprise Linux and CentOS, especially dynamic languages (Python, Ruby, NodeJS) or databases (PostgreSQL, MariaDB, MongoDB).

Recently, while reviewing the FAQ, I came across the question “What’s a Socket?” For those who are not familiar, I shall explain.
In brief, a Unix Socket (technically, the correct name is Unix domain socket, UDS) allows communication between two different processes on either the same machine or different machines in client-server application frameworks. To be more precise, it’s a way of communicating among computers using a standard Unix descriptors file.
