Google Cloud Functions

 

  • A pay-as-you-go function as a service (FaaS) to run your code with zero server management.

Features

  • There is no need to provision, manage, or upgrade servers.
  • Cloud Functions can be written using:
    • Node.js
    • Python 3
    • Go
    • Java
  • Automatically scales based on load without thinking about the infrastructure.
  • Built-in security at role and per function level based on the least privilege principle.
  • Allows you to trigger your code from Google Cloud, Firebase, and Google Assistant or call it directly from any web, mobile, or backend application via HTTP.
  • To act on events, you shall define a trigger. Binding a function to a trigger enables you to act on events. The most common triggers are:
    • Google Cloud Storage 
    • Supported HTTP request types like: POST, PUT, GET, DELETE, and OPTIONS.
    • Pub/Sub

Pricing

  • Cloud Functions is priced according to:
    • how long your function runs
    • how many times it is invoked
    • how many resources you provision for the function

Google Cloud Identity and Access Management

  Create and manage permissions for your Google Cloud resources with Identity Access Management (IAM). Provides a unified view into your organization’s security policy with built-in auditing to ease compliance purposes.

Permissions are represented in the form of  service.resource.verb Can map job functions into groups and roles. With IAM, users only get access to what they need to get the job done. Cloud IAM enables you to grant access to cloud resources at fine-grained levels, well beyond project-level access. You can leverage Cloud Identity to easily create or sync user accounts across applications and projects. IAM lets you set policies at the following levels of the resource hierarchy: Organization level The organization resource represents your company. IAM roles granted at this level are inherited by all resources under t...
