The Alpakka S3 connector can connect to a range of S3 compatible services. One of them is IBM Bluemix Cloud Object Storage, which supports a dialect of the AWS S3 API. Most functionality provided by the Alpakka S3 connector is compatible with Cloud Object Store, but there are a few limitations, which are listed below.

An example configuration for accessing Bluemix Clooud Object Storage should look like this:
