Cloud Functions

• Cloud Functions is a serverless computing platform designed to run single-purpose pieces of code in response to events in the GCP environment
• There is no need to provision or manage VMs, containers, or clusters when using Cloud Functions
• Cloud Functions provides the “glue” between services that are otherwise independent

Cloud Functions Execution Environment

• The functions execute in a secure, isolated execution environment
• Compute resources scale as needed to run as many instances of Cloud Functions as needed without you having to do anything to control scaling
• The execution of one function is independent of all others. The lifecycles of Cloud Functions are not dependent on each other
• By default, the functions will time out after one minute, although we can set the timeout for as long as 9 minutes
• Cloud Function Runtimes:
  • NodeJS
  • Java
  • .NET
  • Ruby
  • Python
  • Go
