IBM Cloud Functions Improves Performance for Python 3.7 Actions

What’s happening with IBM Cloud Functions and Python?

I’m excited to announce that IBM Cloud Functions Python 3.7 runtime has been optimized for latency. The updated Python 3.7 runtime leverages a new web proxy built with Go that replaces the previous Python web proxy. The web proxy allows action invocations to respond faster by providing lower latency for blocking calls.

Ready to try it out?

  1. Create the following Python file.

    def main(args):
    name = args.get("name", "IBM Cloud")
    greeting = "Hello, " + name + "!"
    return {"body": greeting}
  2. Create the helloPython action.

    ibmcloud fn action update helloPython hello.py --kind python:3.7 --web true
  3. Invoke the action.

    ibmcloud fn action invoke helloPython -r
    {
    "body": "Hello IBM Cloud!"
    }
  4. Get the URL for the web action.

    ibmcloud fn action get helloPython --url
  5. Open the URL in your browser.

How much faster is Python 3.7?

Python 3.7 is much faster than previous versions of Python, as you can see in the graph below comparing warm invocation performance. Start new projects by using Python 3.7 or migrate any existing actions.

How do I learn more?

To set up a project and deploy your Python 3.7 action, check out the IBM Cloud Functions documentation.
