Cloud Functions

Cloud Functions is a serverless computing platform designed to run single-purpose pieces of code in response to events in the GCP environment. There is no need to provision or manage VMs, containers, or clusters when using Cloud Functions. Code that is written in Node.js 6, Node.js 8, or Python 3.7 can run in Cloud Functions.

Cloud Functions is not a general-purpose computing platform like Compute Engine or App Engine. Cloud Functions provides the “glue” between services that are otherwise independent.

For example, one service may create a file and upload it to Cloud Storage, and another service has to pick up those files and perform some processing on the file. Both of these services can be developed independently. There is no need for either to know about the other. However, you will need some way to detect that a new file has been written to Cloud Storage, and then the other application can begin processing it. We don’t want to write applications...
