Keeping Containers Warm

By default, Beam is serverless, which means your applications will shut off automatically when they’re not being used.

You can control how long your containers are kept alive by using the keep_warm_seconds flag in your deployment trigger.

For example, by adding a keep_warm_seconds=300 argument to an endpoint, your app will stay running for 5 minutes before shutting off:

from beam import endpoint


# Container stays alive for 5 min before shutting down automatically
@endpoint(keep_warm_seconds=300)
def handler():
    return {}
