Roman Coedo implemented Amazon Glacier support. Implementation of this provider presented challenges due to its long retrieval times and archive storage semantics. jclouds 1.8.0 includes Glacier support.
Bhathiya Supun implemented Google Cloud Storage support. This provider has long been requested by the community and completes jclouds support for all major object stores. jclouds 1.8.1 will include GCS support.
It was my pleasure to mentor both students this summer and look forward to working with Roman and Bhathiya in the future. Special thanks to Andrew Phillips and Ignasi Barrera who helped with code reviews and troubleshooting and to Google for running the Summer of Code. We hope to participate next year!
