Computing with Cloud Functions

Cloud Functions is a serverless compute service provided by Google Cloud. Cloud Functions is similar to Cloud Run in that they are both serverless compute options. Cloud Functions are well suited for event‐driven processing. This chapter describes the purpose of Cloud Functions as well as how to implement and deploy the functions. It uses examples of the functions written in Python. The chapter examines how to use the Cloud Console and gcloud commands to create and manage Cloud Functions. Cloud Storage is GCP's object storage. This service allows cloud engineers to store files in containers known as buckets. A function can be executed each time a message is written to a Pub/Sub topic. Cloud engineers can use Cloud Console or gcloud commands to deploy functions triggered by a Cloud Pub/Sub event.
