AWS Endpoints/URLs with a Greengrass IoT Device

Question

In the case of an AWS Greengrass Core Device (V2) that has components which perform the following:
 - Downloading from AWS S3
 - Subscribing to AWS IoT MQTT Topics + receiving messages
 - Posting to AWS IoT MQTT Topics
 - Uploading to S3 buckets
 - Downloading container images from ECR as part of a Greengrass component

where each of these operations is carried out in a component, being permitted via the TokenExchangeRole,
which AWS endpoints are being used?

In the case of the S3 operations, this page (https://docs.aws.amazon.com/general/latest/gr/s3.html) lists a number of endpoints for our region, which ones of these would be used in the case of a greengrass component interacting with S3?

Answer

The standard AWS SDK is used which means that for S3 the URL would be s3..amazonaws.com.

Hope this helps
