Looking back on AWS Summit Benelux 2018

Last week I visited AWS Summit Benelux together with Sander. AWS Summit is all about cloud computing and the topics that surround cloud computing. This being my first AWS conference I can say it was a really nice experience. Sure there was room for improvement (no coffee or tea after the opening keynote being one), but other than that it was a very good experience. Getting inside was a breeze with all the different check-in points and after you entered you were directly on the exhibitor floor where a lot of Amazon partners showed their products.

To shed some light on what happened professionally let’s take a very quick run through 2016.

Fixing the long startup time of my Java application running on macOS Sierra

At my current project, we’re developing an application based on Spring Boot. During my normal development cycle, I always start the application from within IntelliJ by means of a run configuration that deploys the application to a local Tomcat container.  Spring boot applications can run perfectly fine with an embedded container, but since we deploy the application within a Tomcat container in our acceptance and production environments, I always stick to the same deployment manner on my local machine.
