- Echo Service
Explore how to build and deploy a simple echo service using Google Cloud Functions. Understand setting up HTTP triggers, coding with Python and Flask, and testing serverless functions through the GCP console. Gain practical experience in deploying and invoking serverless endpoints.
We'll cover the following...
GCP provides a web interface for authoring Cloud Functions. This UI provides options for setting up the triggers for a function, specifying the requirements file for a Python function, and authoring the implementation of the Flask function that serves the request.
Getting started
To start, we’ll set up a simple echo service that reads in a parameter from an HTTP request and returns the passed-in parameter as the result.

- Search for “Cloud Function.”
- Click on “Create Function.”
- Select “HTTP” as the trigger.
- Select “Allow
