Functions lifecycle
Reviewed on 15 January 2024 • 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 longer 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.
