APIs have become an essential ingredient of Digital Transformation and other initiatives to modernize IT and organizations. However, while APIs are an essential ingredient, they are not everything you need, and thus only focusing on APIs may lead to disappointment when expectations are running too high.

In the interaction between GraphQL and AWS Lambda, a highly scalable implementation is presented that can be adapted to different architectures and frameworks.
