GCP Cloud Function Instance lifetime

Question

I've worked with the AWS environment for 4 years, mostly with Lambdas. From my experience, I know that an "instance" of a Lambda function will live aprox for 2 hours.

Now I'm going to work for a project with GCP and their Cloud Functions: is there any information about how much time a CF "instance" will live?

I generally need to know that in order to better understand how frequently we will face a cold start.

This can get complicated since Cloud functions can be multi-regional and scale up and down as your apps need, from our experience it was about a 30-minute cooldown.

To quote the documentation:

The environment running a function instance is typically resilient and reused by subsequent function invocations, unless the number of instances is being scaled down (due to lack of ongoing traffic), or your function crashes.
