Serverless execution environment for event-driven code

Core Idea: Google Cloud Functions is a lightweight, event-driven serverless compute solution that allows developers to run single-purpose functions that respond to cloud events without managing servers.

# Simple HTTP function in Python
from flask import jsonify

def hello_world(request):
    """HTTP Cloud Function.
    Args:
        request (flask.Request): The request object.
    Returns:
        The response text, or any set of values that can be turned into a
        Response object using `make_response`.
    """
    request_json = request.get_json(silent=True)
    request_args = request.args
    
    if request_json and 'name' in request_json:
        name = request_json['name']
    elif request_args and 'name' in request_args:
        name = request_args['name']
    else:
        name = 'World'
        
    return jsonify({
        'message': f'Hello {name}!',
        'timestamp': datetime.datetime.now().isoformat()
