• Designed an architecture that facilitates sharing of resources without the need for repeated authentication during task delegation among multiple Openstack cloud deployments that are used for IaaS . This project was done in collaboration with EMC2.
• Understood in detail ,the authorization and authentication component of Openstack ,i.e, Keystone.
• Incorporated the RAT (Resource acquisition token) in keystone, the authorization and authentication component, which issues it to the user of the home cloud once verification by the foreign cloud is complete and enables access to resources until the user deactivates his account or after a preset time period
• Tested the architecture using the home cloud’s threshold resource values and observed delegation of work on the foreign cloud’s resources through Openstack Dashboard statistics.
• Wrote a paper on this project along with team members which was submitted to Springer’s Conference, November 2014.
• Future work includes addressing the issue of portability and interoperability of the code using an upcoming API called Deltacloud, a flexible platform that allows for writing code using generic APIs, which in turn converts it into the cloud specific APIs.
