The diagram flows don't seem correct. Can you use individual lines to show communication. The only flows in this DA are:

• Event Notifications sends failed events to the COS bucket
• The KMS key is used to encrypt and decrypt data
• Event Notifications send platform metrics to Cloud Monitoring
• The COS bucket sends its metrics to Cloud Monitoring

@Ak-sky why is it using a private bucket endpoint? Thats going to fail after re-platforming. It should be using direct

@ocofaigh, I missed this, will fix now.
Should we also remove private from variable validation?
