CrownLabs was born in 2020 during the pandemic as a service for students, to let them practice with laboratory experiences thanks to remote desktop environments. CrownLabs has been started by a group of students and volunteers from Politecnico di Torino, and soon became a real-life playground for experimenting with cutting-edge and production-grade cloud technologies and development techniques (Kubernetes, CI/CD, open-source contributions). This thesis work aims to extend the CrownLabs ecosystem to make it suitable for a larger number of users, and especially to enable it as an exams platform. Hence, allowing students to interact with the same environments they have been studying onto, but in an insulated and protected sandbox that prevents distractions and cheating.
