Different regions for the same service

[ryno1234]

Hypothetically, if I wanted to use the IAmazonS3 / AmazonS3Client, but had different regions I needed to access, how would one go about doing that?

I know I could create a new instance of AmazonS3Client as needed, but I have to pass it credentials, i.e. new AmazonS3Client(awsCredentials);, which skates around the built in credential lookups specified here https://docs.aws.amazon.com/sdk-for-net/v3/developer-guide/creds-assign.html and requires me to know much more about how the credentials are configured (credentials file? IAM role? etc).

If I were to use the recommended way to configure the service, i.e. services.AddAWSService<IAmazonS3>(), I don't have control to configure multiple regions.

A solution here would be to allow some way to resolve AWSCredentials using the same lookup sequence mentioned in the link I just provided, however this doesn't seem to be exposed in the AWS .Net SDK. I thought the AWSCredentialsFactory would be what I was looking for, but turns out that has a different purpose.

@ryno1234 Good afternoon. If you use new AmazonS3Client() or new AmazonS3Client(RegionEndpoint) without credentials, the SDK would try to resolve the credentials automatically using the resolution order mentioned in Credential and profile resolution. If you would like to manually resolve the credentials using the same order, you could use Amazon.Runtime.FallbackCredentialsFactory.GetCredentials() (although this manual step is not required since new AmazonS3Client(RegionEndpoint) would have credential resolution done automatically). Please advise if this answers your question.

Thanks,
Ashish
