Geecon 2015

So last month I've attended Geecon and I really loved it. Geecon is a conference focused on Java and JVM technologies, hosted annually in Cracow (usually).
Geecon had a Steampunk theme
This year’s it was all about microservices, so it’s no surprise that I enjoyed Fred George’s “Challenges in implementing microservices” the most.

In his talk Fred George shared his experiences with replacing monolith applications with microservices. He explained how microservices facilitate a Service Oriented Architecture and “going faster” as shorter reaction time for the whole company.

What was most interesting to me was the comparison of asynchronous and synchronous approaches to microservices. He mentioned his friend Chad Fowler suggests synchronous communication on default mainly because it’s easier for most of the modern programmers. In contrast Fred George believes that asynchronous messaging gives so too much of an opportunity for robustness and graceful degradation to ignore in exchange for simpler implementation.

Well, Fred George convinced me to his approach. But it might have something to do with him being a really cool guy and his grey, sage-like, hair - he joked about it a little.

Sam Newman's talk on microservices was also very compelling, even though he talked about his book an awful lot. Must have worked, because I got it for myself after the conference. ;)

If you'd like to know how my how my friends at Espeo Software enjoyed the conference you can do so here!
