A few years back (2013-2016) I was working as a C++ Software Development Engineer at Intel on a monolithic product with a backend written in C++ and a web frontend written in Java. The product was shipped complete with hardware and as a VMware image.

An introduction to microservices through a complete example
Today I want to talk about the demo we presented @ OpenShift Container Platform Roadshow in Milan & Rome last week.
The demo was based on JBoss team’s great work available on this repo:

Hi there! It’s been a while since I last wrote an article. Today, I want to show you how to easily setup some persistent storage for your projects in minishift / CDK 3 (Red Hat’s Containers Development Kit 3).

In part one of this blog post, we mentioned a pain point in Container based environments. We introduced SCAP as a means to measure compliance in computer systems and introduced ManageIQ as a means of automating Cloud & Container based workflows.

This is the first part of a 2 part article, part 2 (End To End Encryption With OpenShift Part 2: Re-encryption) will be authored by Matyas Danter, Sr Consultant with Red Hat, it will be published soon.
This article aims to demonstrate use cases for Openshift routes to achieve end-to-end encryption. This is a desirable and sometimes mandated configuration for many verticals, which deal with strict regulations.

Containers are one of the top trend today. Starting working or playing with them could be really hard also if you’ve well understood the theory at their base.
With this article I’ll try to show you some useful tips and tricks to start into containers world, thanks also to the great web interface provided by the Cockpit project.
Cockpit is an interactive server admin interface. You’ll find below some a of its great features:
- Cockpit comes “out of the box” ready for the admin to interact with the system immediately, without installing stuff, configuring access controls, making choices, etc.
- Cockpit has (as near as makes no difference) zero memory and process footprint on the server when not in use. The job of a server is not to show a pretty UI to admins, but to serve stuff to others. Cockpit starts on demand via socket activation and exits when not in use.
- Cockpit does not take over your server in such a way that you can then only perform further configuration in Cockpit.
- Cockpit itself does not have a predefined template or state for the server that it then imposes on the server. It is imperative configuration rather than declarative configuration.
- Cockpit dynamically updates itself to reflect the current state of the server, within a time frame of a few seconds.
- Cockpit is firewall friendly: it opens one port for browser connections: by default that is 9090.
- Cockpit can look different on different operating systems, because it’s the UI for the OS, and not a external tool.
- Cockpit is pluggable: it allows others to add additional UI pieces.
