Google Cloud Storage not only a store space... You can use Cloud Storage as you static web server. Put your page right now!
Create a bucket called yourdomain.com that will be your page's domain in the future. Create your index.html, error.html and other resources then upload to your domain named bucket.
Add a CNAME mapping from yourdomain.com to c.storage.googleapis.com to
finish the setting.
Mapping destination: c.storage.googleapis.com
