Functions lifecycle
Reviewed on 12 July 2023 • Published on 13 April 2022
The Serverless Functions runtimes are the environment in which your code runs. We currently support five languages:
- Javascript (NodeJS runtime)
- Python
- Go
- PHP
- Rust
Runtime lifecycle
New runtimes are added periodically, based on user demand.
| Status | Description |
|---|---|
Beta (beta) | The runtime has been released recently, users can test it and provide feedback, but it is not yet suitable for a production environment. |
General Availability (available) | The runtime is available to be used in a production environment. |
When runtimes are no longer supported, they pass through different phases:
| Status | Description |
|---|---|
Deprecated (deprecated) | The runtime is still available, but a warning announcing the upcoming End Of Support displays when a new function is created. |
End Of Support (end_of_support) | 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 (end_of_life) | Functions that use this runtime will still be working, but it is no more possible to update them. |
Runtime upgrade
To modify a runtime version, you simply need to change the runtime value.
For example, to migrate from node18 to node20, change the runtime field and redeploy your function. Deployed runtimes are forward compatible, but not necessarily backward compatible.
Once a function is in a deprecated, end_of_support or end_of_life status, you are invited to upgrade your ongoing runtime to take advantage of new features, better performance and security fixes.
