Boto3 Client Specify Region
When the client gets a request to a bucket a central lookup service could determine the bucket region and send the request there. That however creates a single point of failure. You could work around that by running the lookup service in every region, and having all the endpoints in the client, but that's more code, more configuration, more services to run, more services taking CPU. Kms = boto3.client('kms', regionname='us-west-2') or you can have a default region associated with your profile in your /.aws/config file as in: default region=us-west-2 or you can use an environment variable as in: export AWSDEFAULTREGION=us-west-2 but you do need to tell boto3 which region to use. Client = boto3.client( 'autoscaling', awsaccesskeyid=AWSACCESSKEY, awssecretaccesskey=AWSSECRETKEY, ). NoRegionError: You must specify a region. Turn out you can set the region by passing regionname.
