Functions lifecycle

Reviewed on 13 April 2022Published on 13 April 2022

The Serverless Functions runtimes are the environment in which your code runs. We currently support three languages:

  • NodeJs
  • Python
  • Go

Runtime lifecycle

New runtimes are added periodically, based on user demand.

BetaThe runtime has just been released, users can test it and provide feedback, but it is not yet suitable for production environment.
General AvailabilityThe runtime is available to be used in a production environment.

When runtimes are no longer supported, they pass through different phases:

DeprecatedThe runtime is still available, but a warning announcing the upcoming End Of Service displays when a new function is created.
End Of Service (EOS)It is no longer possible to create a new function with this runtime; however, functions that already use it can still be updated. A message with the date of End of Life is displayed.
End Of Life (EOL)Functions that use this runtime will still be working, but it is no more possible to update them.
