Does anyone know, difference between Google App Engine Flex and Google Cloud Run?
Thanks

The Cloud Run documentation is not yet very informative but the new video Where Should I Run My Code? Choosing From 5+ Compute Options (Cloud Next '19) compares Cloud Run with App Engine and also Cloud Functions, Google Kubernetes Engine, and Google Compute Engine.
- You can choose to deploy your Cloud Run app on fully managed infrastructure ("serverless", pay per use, auto-scaling) or on a Google Kubernetes Engine cluster. App Engine is always fully managed, with auto-scaling. App Engine Flex auto-scales gradually and down to 1. App Engine Second Generation auto-scales up rapidly and down to 0.
- Cloud Run requires your app to run in a container. App Engine Flex runs your container for any language runtime. App Engine Second Generation provides a few language runtimes.
- Cloud Run runs "HTTP request/response" workloads, not necessarily for web browser requests. It's allowed to take a long time to process a request. App Engine runs HTTP web apps. It has modest request timeouts; different timeouts for App Engine Classic, Standard, and Flex.
- Cloud Run is designed for teams that include both software developers and ops experts. App Engine is designed for developers.
- Cloud Run is beta software. App Engine is battle tested and serving many billions of requests per day.

Google cloud runs utilizes stateless applications inside docker containers. The service can scale up and down automatically and will scale to 0 when not in use. From what I understand app engine flex cannot scale to 0 and is generally not considered a stateless architecture.
