Use Google Cloud Armor as a WAF layer along with Apigee. Use reCAPTCHA Enterprise for user authentication and authorization, which helps you avoid bots from accessing your application or API. You can also use it to prevent spamming of forms on your website or web app by spammers who try to submit the same form multiple times using different email addresses.

Use Cloud CDN for caching

Cloud CDN is an effective way to cache static content such as images, videos, CSS files, JavaScript files etc., so that they are served faster than if they were loaded directly from the origin server (your back end)
