We use Lambda for our event processing pipeline and also for our GraphQL API consumed by our clients (frontend management application, mobile applications, etc). The GraphQL API is backed by DynamoDB and is served via API Gateway. The frontend was built using ReactJS and Relay. I am currently seeing anywhere from 200-450ms per GraphQL request on the frontend, which is more than acceptable as it's just a management frontend application...and of course it may be optimized using techniques such as prerendering, caching, etc...but these applications being super optimized is not a requirement.
