In addition, other resources used with Google Cloud Armor might also have quotas.

Google Cloud enforces quotas on resource usage for many reasons. For example, quotas protect the community of Google Cloud users by preventing unforeseen spikes in usage. Google Cloud also offers free trial quotas that provide limited access for projects that are only exploring Google Cloud on a free trial basis.

Not all projects have the same quotas. As your use of Google Cloud expands over time, your quotas might increase accordingly. If you expect a notable upcoming increase in usage, you can proactively request quota adjustments from the Quotas page in the Google Cloud Console.
