VT OCCI for CMF

General Project Information

• Full title: Providing OCCI support for arbitrary Cloud Management Frameworks
• Leader: Boris Parak, CESNET
• Mailing List: inspire-mp-rocci@mailman.egi.eu
• Status: active
• Start Date: 01/04/2013
• End Date: 31/03/2014

Motivation

The mini-project aims at providing an ability to control the life-cycle of virtual machines at multiple sites of EGI's federated cloud environment using standardized tools. As different cloud management platforms are already actively used at different sites, enforcing a particular platform across all sites at this point is neither practical nor desirable. Therefore there is a need for an interoperability layer to bridge this gap. The OCCI protocol, an OGF standard, has been chosen to provide a uniform interface for the management of virtual machines.

For implementation, the rOCCI framework and the rOCCI-server have been selected to add OCCI support to existing applications and cloud management platforms. By using their existing features, and extending their architecture to include an interoperability layer based on the fog.io abstraction library for cloud services, this project will provide OCCI support for a large number of open source and commercial cloud platforms including OpenNebula, OpenStack, RackSpace, CloudStack and AWS with focus on extended support for cloud platforms used within the EGI Federated Clouds Task Force.

Progress

Only higher-level progress statemets will be listed here. Day-to-day tasks are tracked at Asana.com

• Task 1 (CONTINUOUS)
  • Progress report at EGI TF 13 in preparation
• Task 2 (In PROGRESS)
  • Refactoring finished for practical purposes. Original rOCCI package split into:
    • rOCCI-core
    • rOCCI-api
    • rOCCI-cli
  • Documentation in preparation
• Task 3 (In PROGRESS)
  • Ongoing
• Task 4 (In PROGRESS)
