Sometimes you might need to check connectivity between the CDRS and CDRA, and not always you are able to connect to it using SSH. There is an option to use REST API to test connectivity using Swagger UI:
This can be useful, for example, to test connectivity between the CDRA to the CDRS or to an AWS S3 bucket, as every bucket has a public URL in the following format: bucketname.s3.region-code.amazonaws.com,
For example:
my-bucket.s3.us-west-2.amazonaws.com
And get a response of connected or not_connected.
