I am surprised to hear about on-prem deploys when the direction of travel is towards serverless/cloud solutions that don't require orchestration. Out of interest, why is on-prem so important for your use case? Separately, I'd be interested in how you'd view that decision if there was a less scalable but mostly fully functioning open source version of the third-party service you could deploy if you needed to?
