Let's be honest, systems age and while we try hard not to accumulate technical depth, sometimes you realize it's time for a bigger change. In this case, we looked at a Haufe owned platform providing services like user-, licence- and subscription management for internal and external customers. Written in Java, based on various open source components, somewhat automated, fairly monolithic.

What started as a little get together in one of our locations last year, grew a little bit bigger - last week 150 Haufe colleagues met in Freiburg for our internal DevOps Day 2016. Taking the opportunity of so many tech people in town, we also set up a public [DevOps meetup](http://www.meetup.com/de-DE/DevOps-Freiburg/events/231185858/) in the evening.

[Here is our Open Source][github] project on Github after some digging into Eloqua documentation and building some docker files. Take a couple of minutes and read the entire story.

+[This week in Open Tabs](http://dev.haufe.com/meta/category/opinion/) is my new weekly column to share the list of links I have (or had) open in my browser tabs to read during this week.
+
+I was looking for a format to easily share these with the larger developer and business community here at Haufe, but it might also be of interest to others. My goal is not to be comprehensive or most up to date, but to provide a cross section of the topics I find interesting and worth investing my time in.
+
+Depending on the week you might find some interesting links or nothing at all. And that is ok. I might even include some stories from the trenches or decide that they warrant a separate column. That is ok too. I might even include links I collected in Evernote as reference material for the future. I am sure you don't mind that, or? The only constrain I would like to set myself is that it should be only the material of a single week. Not more and not less.
+
+So without much ado, here is the first **Open Tabs** editions for the week of August 29th.
