I don’t know of anyone using no-AWS managed services as event source for Lambda.

Thanks for your feedback! Actually we are currently developing our product using lambda / Kinesis / DynamoDB but as usage grow I anticipate the costs are going to soar. We have other teams not using lambda which are operating Kafka and Redis / Cassandra, so I am having this consideration.

Great to read your posts anyway! By chance, are you working in Singapore? If that’s the case, I’d love to organize a BBL (Brown Back Lunch) to share your experience and the experience of our team.
