opsi is an OpenSource Enterprise Client Management System for central administration of Windows-, Linux- and Mac-Clients (Mac-Support has not been released yet)

opsi is also a project with a long history. The requirements increased immensely over the years. opsi manages today environments with several hundred locations and more than 10000 clients in a central administration.

During the development of the new version of opsi it was first decided to change to a micro service architecture. Why this decision? What did we learn on our way and why did we finally decide against a microservice architecture again?

In this presentation we take the audience on a journey through our development on opsi 4.2 and show how we have technically set the new basis for the opsi web service. Finally there is a conclusion, what exactly the modification compared to the old version has brought and what the opsi users can still look forward to with opsi 4.2.
