A Presentation about Payara Platform and MicroProfile in Warsaw

08 Jan 2019

In November, my friend Milen Dyankov started it all by inviting me to come to Warsaw to give a talk at a local developer meetup (sponsored by Liferay, Milen's employer). After attending several big conferences during the year, coming to talk at a much smaller event sounded quite relaxing! Visiting Warsaw for the first time was also tempting so I agreed to attend.

 

The event was organized in a warm and cozy pub in the center of Warsaw. It was serving countless brands of beer of different tastes and had a delicate atmosphere of a small mountain cottage. Very lovely!

Milen had asked me to give a talk about Microprofile, so I prepared a presentation about writing reactive applications with MicroProfile which I also gave in Sofia recently. Click here for the slides.

As the audience was much smaller than usual and the atmosphere more familiar, my talk quickly turned into a discussion about reactive programming and how it is different to a traditional approach to programming. We then delved into where reactive programming is useful and where it's counterproductive and how to adopt reactive concepts in a sensible way. Later, we even touched on the idea of evolutionary development, starting with simple architecture and gradually evolving to more complex, asynchronous, and even reactive architecture once there's a need for it. We also discussed what Eclipse MicroProfile is, the people behind it and how the Eclipse Foundation provides a great collaborative platform to evolve this set of Java specifications.

 

Piotr, who organized the event, told me there were some people who wanted to come but couldn't. For those, as well as for all of you who couldn't come, I'm sharing a recording of a similar presentation I gave at Devoxx this year:

Because Piotr asked me to share as much as possible about the topics we discussed, I'm also sharing a presentation I did a while ago about refactoring traditional applications to reactive:

I also explain evolutionary development in more detail in my other presentation, which I also gave in Sofia last month. Here are the slides to give you some pointers and food for thought:

I also mentioned the Vert.x framework, which is a neat reactive framework and is useful when there's an extensive need for optimal use of system resources by an application. However, we concluded that MicroProfile is much simpler to work with for people just coming to reactive programming. It's a nice compromise because it allows mixing both traditional and reactive programming in an elegant and productive way.
