Merci Duchess et Devoxx!

We’ve had two very hectic weeks delivering the Infinispan/http://vertx.io/[Vert.x]/https://www.openshift.com/[OpenShift] Streaming Data workshop in Duchess France and Devoxx Belgium. First of all, thanks to all attendees for taking the time to attend this workshop and working through it, thanks Duchess and Devoxx for letting us present the workshop, and thanks the sponsors for making it happen!

In case you want to walk through the workshop at your own pace, the version of the workshop delivered at Duchess and Devoxx can be found here. The slides from the workshop can be found here.

The aim of the workshop was to show how to work with multiple data streams and combine them in interested ways. These two streams of data came from Transport API at OpenData.ch and SBB.ch respectively. The end-game of the workshop was to see to combine both sets of information to produce a map that tracked positions of delayed trains around Switzerland.

On 2nd November we did a dry run of the workshop in the Duchess France group. This was a very compact group of people, around 10-12, which gave us thve first taste of what it was like to work through it. In particular, we realised that getting Virtual Box to run on each attendees laptop took some time to get working. From the workshop perspective, we found that the exercises themselves were a bit too long for the people to complete.

With all the invaluable input, Katia, Thomas and myself got ready for delivering the workshop at Devoxx Belgium, one of the top developer conferences in Europe. The pressure was on! We had ~60 attendees, so we had to make sure everyone could progress.

At Devoxx, we were more prepared to help out with set up problems, so everyone got to the starting point much faster. After working through the initial exercise to get used to Infinispan, Vert.x and OpenShift, attendees got on with the workshop itself.

During the workshop exercises, the learnt about Infinispan’s in-memory data grid capabilities, and in particular about continuous query which is very well suited for feeding data to live updating maps or dashboards. They also learnt about how easy it is to build reactive applications with Vert.x and RxJava. Finally, they learnt how to deploy applications to OpenShift, how to monitor their progress…​etc.

A majority of Devoxx attendees managed to get to the end of the workshop which was a success for us, but we listen to their feedback and we will continue to improve the content and delivery as we prepare for Codemotion Madrid where we are delivering the workshop once again.

Thanks attendees, Devoxx, Duchess and sponsors!!

Cheers, Galder
