Where is the endpoint for receiving metrics when launching InfluxDB Cloud from AWS marketplace

1

From my understanding, metrics need to be sent to an endpoint so that InfluxDB could store those data.
My question is:
If I launch InfluxDB Cloud from AWS marketplace AWS Marketplace: InfluxDB Cloud.
Where will be the endpoint located? Within my AWS account through a private url? or outside my AWS account through a public url?
Where could I find architecture diagram such deployment
