Google Cloud Functions , as a new exciting serverless environment to build and connect cloud services
At the core of stakes, we have the ability to build and connect cloud services without having to manage infrastructure.
I can observe that, Cloud Functions can be a great way to build lightweight backends, and to extend the functionality of existing services. For example, Cloud Functions can respond to file changes in Google Cloud Storage or incoming Google Cloud Pub/Sub messages, perform lightweight data processing/ETL jobs or provide a layer of logic to respond to webhooks emitted by any event on the internet.
Developers using Firebase can build backends integrated with the Firebase platform. Cloud Functions for Firebase handles events emitted from the Firebase Realtime Database, Firebase Authentication and Firebase Analytics.
