Cloud standards interoperability: status update on OCCI and CDMI implementations
1 like1,310 views
This document provides a status update on implementations of the Open Cloud Computing Interface (OCCI) and Cloud Data Management Interface (CDMI) standards. It discusses several active OCCI and CDMI client and server implementations from various organizations. It also describes the SNIA Cloud Plugfest events which bring together vendors to test interoperability between their OCCI and CDMI implementations. The document outlines the goals of further advancing the standards based on implementation experience and expanding testing of combined OCCI, CDMI, and OVF capabilities.
Cloud standards interoperability: status update on OCCI and CDMI implementations
- 1. Service Computing Group/ITMC CLOUD STANDARDS INTEROPERABILITY: STATUS UPDATE ON OCCI & CDMI IMPLEMENTATIONS Florian Feldhaus TU Dortmund
- 2. Service Computing Group/ITMC Overview OCCI • RESTful API for Service Management (IaaS and more) • consisting of 3 parts (OGF proposed recommendations) • Core – defines the OCCI model • Rendering – defines RESTful rendering using text/plain or text/occi (JSON and XML in next version) • Infrastructure – defines IaaS resource parameters • compute • storage • network • easily extendible by • linking to new or external objects and services • adding new attributes to existing objects • very flexible API • active development and existing implementations
- 3. Service Computing Group/ITMC Overview CDMI • RESTful API for Cloud Data management • developed by SNIA • main concepts • object storage • support for legacy storage • containers for grouping • metadata • simple management
- 4. Service Computing Group/ITMC SNIA Cloud Plugfest • purpose is for vendors to to bring their implementations of CDMI and OCCI to test, identify, and fix bugs in a collaborative setting • organised by Storage Networking Industry Association • 1st plugfest April 2011 at SNIA Technology Center • 2nd plugfest July 2011 at SNIA Technology Center • 3rd plugfest will be Sep. 19 – Sep 22. 2011 in Santa Clara • 4th plugfest will be spring 2012 in Europe • remote participation encouraged • implementations and test instances will be collected in a wiki • http://plugfest.sniacloud.com/wiki/index.php
- 5. Service Computing Group/ITMC Status OCCI Implementations • OCCI 1.1 Client / Server frameworks • OCCI for OpenNebula – Ruby framework, OpenNebula, SLA@SOI • occi-py – Python Framework, developed by OGF (Ralf Nyren) • occi4java – Java Framework, developed by TU Dortmund University • pyocci – Python module, part of Service Sharing Facility developed by Platform Computing • OCCI Client libraries • R2AD-Cloud-Client – JavaFX + Android implementation developed by R2AD • jClouds integration – soon to be released by SLA@SOI EU project • OCCI Verification Suite • developed by OGF OCCI WG to verify standard conformity • more implementations and information: • http://occi-wg.org/community/implementations/

Service Computing Group/ITMC Status CDMI Implementations • SNIA CDMI Reference Implementation • reference implementation & installation with OCCI / CDMI support • developed by SNIA • NetApp CDMI Server • developed as closed source by NetApp, but testing instance available to Plugfest participants • CDMI-Proxy • CDMI proxy server for public cloud backends e.g. AWS, Azure • developed as part of VENUS-C EU project under BSD license • CDMI client libraries • Python – developed by VENUS-C, BSD license • Java – developed by VENUS-C, BSD license • Ruby (under dev.) – developed by OpenNebula, Apache 2.0 license

- 16. Service Computing Group/ITMC Outlook • several active OCCI and CDMI implementations • progressing well into production ready solutions • integration of OCCI and CDMI works well • OVF integration under active development • SNIA Cloud Plugfest important for testing interoperability • next steps: • advance standards using exerpience from implementations • write implementation experience guides • develop combined OCCI / CDMI / OVF verification suite • stress/scaling testing • interoperability testing • extending OCCI with monitoring / reservation capabilities
