Standards and Implementations Tested To Date
Previous plugfests have focused on self-consistent simultaneous use of the following cloud standards, as identified in the US NIST Cloud Standards Inventory and the EU-funded SIENA Cloud Standards Roadmap Project:
  • Open Cloud Computing Interface (OCCI) from OGF
  • Cloud Data Management Interface (CDMI) from SNIA
  • Cloud Infrastructure Management Interface (CIMI) and Open Virtualization Format (OVF) from DMTF
Participants in past Cloud Plugfests have made use of the following implementations for integration and testing. Core frameworks utilised to date are:
  • rOCCI & OpenNebula. You can read more about the rOCCI framework in this blog post.
  • OCCI & OpenStack. You can read more about the OpenStack OCCI work in this blog post.
  • Many other OCCI related libraries that can be found at the OCCI website.
  • CDMI Reference Implementation.*
  • CDMI implementation of NetApp StorageGrid
  • VCDM an open source CDMI implementation
  • R2AD Android and JavaFX CDMI/OCCI/OVF clients
* This working draft CDMI Reference Implementation has been released so that developers can get started with integrating CDMI into their products and applications. Its current target is the publicly available CDMI v1.0. As the SNIA Cloud Storage Technical Working Group (TWG) continues to create additional functionality, subsequent releases of the CDMI Reference Implementation will be made available.

Further implementations of these and other cloud standards-based API protocols can be found on the web pages of these and other related software projects linked here.

An approach to cloud interoperability put forward by previous Cloud Plugfest participants was detailed in an article on InfoQ.com and contained information on how standards can be combined -- for example, how OCCI attributes could be mapped to OVF ones. Since then, much work has been carried out in implementing this approach in the context of the OpenStack, OpenNebula, and DeltaCloud open source software projects, and a demonstration of EC2 interface capability has been carried out to demonstrate the flexibility of open standards-based approaches to incorporate interfaces to other popular APIs.

As the series progresses, participants intend to fold in, substitute, augment, test and enhance implementations of these and other new and emergent cloud computing industry standards.  Participation is welcome from any organization or group that wishes to test cloud standards implementations in this setting, governed by the Participation Agreement.

A wide variety of other relevant framework projects, implementations and efforts are also being pursued by the community.  Please join our general mailing list and/or see the list of participant tools for more information.
