    You can stream logs from the command line by running:
    $ gcloud app logs tail -s default

    To view your application in the web browser run:
    $ gcloud app browse

By default, the new application is publicly accessible.

There are many ways to protect web applications from unauthorized access. On Google Cloud, BeyondCorp Enterprise is an enterprise scale zero trust platform that enables customers to define fine-grained access level policies leveraging security signals from a variety of data sources including device, user identity profile, network and third-party security solution.
