This week, I’m attending the 19th edition of the Devnexus conference in Atlanta! In those 19 years, Devnexus has truly grown to being one of the biggest Java and JVM-related conference in Nothern America, and it’s always been a pleasure to be there. This year marks my fourth attendance as a speaker, and I’ll be doing two talks myself.

In this post, I’ll be live blogging about some of the sessions that I’ve joined. Enjoy!

Last week, I attended JavaZone, the annual conference ran by javaBin, the Norwegian Java User Group. I have attended JavaZone in the past (2018) so I knew what to expect - and the bar was high! Because of that, I was looking forward a lot to join JavaZone again. Also, this would be my first conference as a Java Champion, which made it even more special.

It’s been a while since the first two posts about Dapr! In those first installments, we looked at the basics of Dapr, from a very conceptual point of view. We also looked at the bare minimum HTTP API that Dapr exposes to the applications that use it. But writing enterprise applications that way would be slow, and it would inevitably lead to mistakes. In this article, I will introduce you to a higher abstraction level of working with Dapr.

Earlier this month, I introduced you to Dapr, the Distributed Application Runtime. That was a mostly conceptual introduction, showing you how Dapr works and what it can do for you. But how do you integrate it into an existing application? That’s the topic for today.

Building distributed applications or microservice applications brings a whole new range of problems. All those application components, or microservices, need to communicate with each other. How will we do that: using messaging, or would direct HTTP calls be a better choice? Often, we must make such decisions early in a project. Since it’s hard to change it later, we call it an “architectural decision”. But this is often an excuse so we can blame the architect if the choice turned out to be wrong.

Together with four “AwesomeSauce” colleagues from Info Support, I’m attending DevNexus this year. For me, it’s the second time I’m here, as I spoke here in 2018, too. Next to delivering my own “React in 50 minutes” session I’m attending some sessions to update with new technology advancements. After a great first day, let’s move on to the second (and last) day.
