Microservices in Action at the Dutch National Police

Microservices? At the Police? Definitely!

At the Cloud, Big Data and Internet division of the Dutch National Police, 3 DevOps teams use the latest open source technology to build high tech web applications. These applications are used to support digital investigation and incident response with data from open, online sources and are built using Spring Boot, Angular 2.x, Spark, Kafka and Jenkins 2.

In this session, Bert Jan will share their experiences and real-world use cases for microservices. He will explain the architecture, why it was chosen, which challenges were faced and how this brought the three teams together to work on one product, loosely based on the models used by Spotify and Netflix.

Bert Jan will also share how the principles of DevOps and Continuous Delivery were applied, and how security, build pipelines, test automation, performance tests, automated deployments and monitoring were handled.

You'll leave this session with an understanding of how this approach enabled the team to have the agility of a startup within the large Police organisation. .

Building Microservices with Vert.x

Vert.x is a toolkit for building reactive applications on the JVM. It is event driven, non blocking and polyglot, which makes it an excellent platform for building microservices. It was awarded for 'Most Innovative Java Technology' at the JAX Innovation awards.

In this talk, Bert Jan will share experiences and real-world use cases from a Dutch company that started building reactive web applications with Vert.x about 4 years ago. You'll learn the concepts behind Vert.x, why Vert.x was chosen, how it is being used and the challenges that were faced.

Topics include the anatomy of the projects, (micro)services architecture, deployment model and DevOps, scalability, the upgrade from Vert.x 2 to Vert.x 3 and cooperation with the team behind Vert.x.

At the end of this session, you'll know enough about Vert.x to get started yourself right away!
