Summary

In this chapter, we worked with Cloud Functions and saw how to implement and deploy functions. We used examples of functions written in Python, but they could have been written in Node.js as well. Functions can be created using either the Google Cloud Console or the command line. To use Cloud Functions, it is important to understand the relationship between events, triggers, and functions. Events are actions that happen in the cloud. Different services have different types of events. Triggers are how you indicate you want to execute a function when an event occurs. Functions refer to the code that is executed when an event occurs that has a trigger defined for it.
