Abstract: With the availability for public comments of the "The NIST Cloud Federation Reference Architecture" SP500 draft, we wanted to renew the conversation about the current cloud ecosystem; one in which cloud providers do not interoperate. This has led to a growing recognition that the lack of cloud federation in a landscape of multiple independent cloud providers is a technical and economic challenge. The federation of clouds is essential and necessary enabling technology for the development and translation of innovations in IoT, high-performance computing, distributed big-data analytics, and global scientific collaboration.

Long Description: The current cloud ecosystem is one in which cloud providers do not interoperate. This hinders the service reach, resources, and scalability that can be offered to cloud users and researchers. This has led to a growing recognition that the lack of cloud federation in a landscape of multiple independent cloud providers is a technical and economic challenge. The federation of research clouds is essential and necessary enabling technology for the development and translation of innovations in IoT, high-performance computing, distributed big-data analytics, and global scientific collaboration.

This BoF takes a critical look at some of the current work in cloud federation, standards and how supporting scientific research computing toward a cloud-agnostic approach to federate all sorts of clouds with a focus on the federation of data, identity, security, shared compute and storage; and an interoperable cloud services management platform can be realized.

In 2018, we presented a panel on "Federated Cloud: An Evolutionary Path from Grid Computing". Since then, the work of the Open Research Cloud Alliance and the NIST Public Working Group has continued.

Earlier in July, and after over 20 months of collaboration with talented contributors, the public comments phase of "The NIST Cloud Federation Reference Architecture" draft SP500 document debuted.

As we are continuing the road to cloud federation, we open the conversation to a member of the OpenStack Keystone project, as they are implementing a proof of concept within their own services to support OpenStack cloud to foreign cloud identity techniques.

We intend during this BoF to continue the conversation started at the previous panel, discuss the comments that were introduced to the draft document and continue the conversation toward the development solutions for cloud and research clouds to interoperate.
