Hi Roberto,
You can use Firebase for the Push Notifications <https://cloud.google.com/solutions/mobile/mobile-app-backend-services#connect-notifications> and keep using Datastore by using Cloud Functions, since Firebase and GCP share Cloud Functions <https://firebase.google.com/firebase-and-gcp/>. In this documentation <https://cloud.google.com/solutions/mobile/mobile-app-backend-services>, you may find the design patterns demonstrate different ways to use Cloud Platform to create backend services for Mobile Apps, and using Cloud Endpoints is one of the five approaches. As you mentioned The Endpoints Frameworks supports doesn't support Python 3.x <https://cloud.google.com/endpoints/docs/frameworks/python/about-cloud-endpoints-frameworks#requirements>. I should note that, here we can neither provide you any architectural recommendation nor any ETA or promise for Python 3.x support. However the Cloud Endpoints product team welcome all the feature requests <https://cloud.google.com/support/docs/issue-trackers> and prioritize them based on their importance and the stars they have taken. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
