SESAM = SUMO in the Cloud

Despite their value, tools for traffic simulations like Eclipse SUMO are hard to use and require consistent effort for maintainance - making it especially hard for planners without a strong IT background. We would like to present SESAM - a "web service shell" for Eclipse SUMO. SESAM offers a comprehensive and scalable solution for urban traffic planning and simulation.

MicroProfile OpenAPI - code first or design first?

Peter Steiner (Worldline | SIX Payment Services)

You're given the task of writing a microservice AND providing a documentation in OpenAPI format. You already know that there are two main approaches:

design-first : write the OpenAPI document (a.k.a. the openapi.yaml file) and then generate the code
code-first : write the code, using OpenAPI annotations, and then generate the OpenAPI document

Which approach do you choose?

I'll compare the two approaches by showing a simple Java microservice implemented twice, once design-first and once code-first.
