Choosing the best serverless option for each use case

After reviewing Cloud Functions, App Engine, and Cloud Run, let’s compare them to clarify when each fits best.

Cloud Functions is a function as a service offering, while App Engine and Cloud Run are platform as a service offerings to deploy code and containers, respectively, requiring a bit more work to prepare a deployment. While all three can overlap as alternatives for many use cases, there are some differences to consider before making our choice.
