The eGTLabs Mu toolkit for unified cloud deployments. This gem contains the Mu deployment interface to cloud provider APIs. It will generate a sample configuration the first time it is invoked. Mu will attempt to autodetect when it's being run in a virtual machine on a known cloud provider and activate the appropriate API with machine-based credentials. Installing this gem on an Amazon Web Service instance, for example, should automatically enable the MU::Cloud::AWS layer and attempt to use the machine's IAM Profile to communicate with the AWS API.
