How to build an event-driven serverless app

Do you want to learn how to design and build an event-driven serverless app? Welcome back to Serverless Expeditions! In this episode Developer Advocates Martin Omander and Terry Ryan look over the Storage Event Function App template application. Let’s dig in and learn how to write an event-driven, serverless application!

You're explanation and pleasant background music is amazing😍

Thanks @TheMomander for the demo, easy to understand architecture!
Going to share it to my LinkedIn and Twitter network 🙂

Thank you, this helps a lot to learn google cloud

Would be nice to have a large terraform project where several buckets, cloud run's and cloud functions are involved. Perhaps with event arc and workflows as well included. Additionally different dev environments would be a bonus.

Another great video Martin 👏🏻 we would love to see a demo of event driven function based on BQ events like insertion/updation in table records.

I usually avoid Cloud Storage events, as uploading a file from inside a function carries the risk to trigger the function, that uploads the file, ...etc => infinite loop. I'm not saying GCS events do not tackle some specific problems, but be very careful when using this pattern and ask yourself if there is not an other way, like a plain old declarative HTTPS invokation.

Why don't you use Eventarc for this demo? It's the new modern way to perform event driven on GCP!

Pulumi is impressive and some woudl say better than Terraform, worth looking to intergrate more examples based on Pulumi!

It would be great to showcase a microservices app composed of multiple cloud run services some of them being internal essentially focus here is on setting up service-service communication and also making these services private similar to a microservices app hosted on GKE for example.
