Great question, I'm also from Germany so I understand your GDPR pain :)
Prefect has innovated the
hybrid execution model that keeps your
code and
data private while still taking full advantage of a managed workflow orchestration service in Prefect Cloud. This hybrid model provides cloud convenience with on-prem security. It all sounds a bit like marketing language, so let's explain it more down to earth:
• your orchestration layer is Prefect Cloud
• your execution layer i.e. your agents live on your infrastructure
• both communicate purely via outbound requests from your agents to Cloud API - never in the other direction - this way, your code and data never leaves EU and Prefect also never sees your code or data, it operates purely on metadata
