No server management
Deploy your code and let Google run and scale it for you.
Cloud Functions abstracts away all the underlying
infrastructure, so that you can focus on your code and
build applications faster than ever before.
Pay only while your code runs
Cloud Functions are ephemeral, spinning up on-demand and back
down in response to events in the environment. Pay only while
your function is executing, metered to the nearest 100
milliseconds, and pay nothing after your function finishes.
Scales automatically
Serve users from zero to planet-scale without even thinking
about any infrastructure. Cloud Functions automatically manages
and scales underlying infrastructure with the size of
workload.
Runs code in response to events
Cloud Functions allows you to trigger your code from Google
Cloud Platform, Firebase, and Google Assistant, or call it
directly from any web, mobile, or backend application
via HTTP.
Connects and extends services
Cloud Functions lets you treat all GCP, Firebase, Google
Assistant, and 3rd-party cloud services as building blocks,
connect and extend them with code, and rapidly move from
concept to production.
Open and familiar
Cloud Functions supports code written in JavaScript (Node.js), Python, and Go.
There are no new languages, tools, or frameworks to learn.
All you need to do is bring code — including native libraries
you bring to the platform.
Supported event sources
Cloud Pub/Sub
You can invoke Cloud Functions in response to messages
published to Cloud Pub/Sub topics. Cloud Pub/Sub is a
globally distributed message bus that automatically scales
as you need it and provides a foundation for building your
own robust, global services.
Tutorial
Cloud Storage
You can invoke Cloud Functions in response to change
notifications from Cloud Storage such as object
addition (create), update (modify), or deletion.
Tutorial
HTTP
You can invoke Cloud Functions directly over HTTP(S).
Each function is given a dedicated domain and a
dynamically generated SSL/TLS certificate for secure
communication. Function execution result is returned
in response to an HTTP request.
Tutorial
Stackdriver Logging
You can invoke Cloud Functions in response to log changes
in Stackdriver Logging. Stackdriver Logging allows you to
store, search, analyze, monitor, and alert on log data
and events from Google Cloud Platform and Amazon Web
Services (AWS).
Tutorial
Firebase
You can invoke Cloud Functions in response to
mobile-related events from Firebase such as changes
to data in the Realtime Database, new user sign-ups
via Auth, and conversion events in Analytics.
Tutorial
Logging, monitoring, and debugging
You can monitor and troubleshoot performance of your
functions using Google Stackdriver suite of tools.
Logging
Logs emitted from your Cloud Functions
are automatically written to Stackdriver Logging

Monitoring
Cloud Functions performance telemetry is recorded in
Stackdriver Monitoring

Debugging
You can investigate your code’s behavior in production
using Stackdriver Debugger

Error reporting
Errors emitted from your functions are automatically
captured and reported in Stackdriver Error Reporting

Developer experience
Building and testing
You can create, manage, and deploy Cloud Functions via
the Cloud SDK (gcloud), Cloud Console web interface, and
both REST and gRPC APIs. Build and test your functions
using standard Node.js, Python, and Go runtimes along with
your favorite development tools.
Learn more
Deploying
You can deploy Cloud Functions from your local machine
or from a source repository like GitHub or Bitbucket.

Automatic dependency resolution
You do not need to package up your entire function
along with its dependencies for deployment. Send us
your source code and your manifest and we will do
the rest.
