As part of the Programmier Praktikum 2020 at TU-Berlin, we had two teams of students migrate the participatory environmental data platform opensense.network to the serverless platform OpenWhisk.
Both teams learned a lot, find their experience reports here and here. One of there crucial findings is that you still need to refactor applications a lot to utilize FaaS platforms fully.
We hope that the SMILE project can reduce this developer overhead in the future!
