Firebase functions Realtime Database

Google Cloud Functions is a serverless execution environment for building and connecting cloud services . With Cloud Functions you write simple, single-purpose functions that are attached to events emitted from your cloud infrastructure and services. Your function is triggered when an event being watched is fired.

Cloud Functions for Firebase is a serverless framework that lets you automatically run backend code in response to events triggered by Firebase features and HTTPS requests . Your JavaScript or TypeScript code is stored in Google’s cloud and runs in a managed environment.

Cloud Functions is available on all Firebase pricing plans, including our free tier. The free tier allows you to quickly experiment and try out integration with other Firebase products. For our Blaze plan, you only pay for what you use. Blaze customers also receive a monthly allotment of free usage for Cloud Functions.

Pricing. Cloud functions in general are very cost-effective . It’s difficult to compare pricing of cloud providers, but I can say that based on my experience, Firebase Cloud Functions have been ridiculously cheap. It’s hard to believe Google is making any money out of this.
