3. No Servers? Really??

4. Cloud Functions
A serverless environment to build and connect
cloud services with code

5. Cloud Functions

6. import flask
import requests
def getUserDetails(request):
user = requests.get('https://randomuser.me/api/').json()
user = user['results'][0]
user['generator'] = 'google-cloud-function'
return flask.jsonify(user)
main.py

Output

9. With 3 lines of code..
● HTTP endpoint
● Fully qualified domain
● Dynamically generated SSL/TLS cert
● Autoscaling
● No infrastructure worries

10. Use cases

11. Should I go serverless with Cloud Functions?
● Existing monolithic applications
● Long-running compute tasks
● Guaranteed response times (synchronous)
● Stateless / ephemeral

12. Thanks!
