Motivation for Federation

• Heterogeneity of cloud platforms:
  • Cloud manager: StratusLab, OpenStack, OpenNebula...
  • Resources.
  • Quota.
• Geographical distribution.
• Interoperability:
  • Resource migration and redundancy: downtime of the Cloud due to failure or upgrade/update.
  • Disk image contextualization.

Federation of French Cloud infrastructure in the academic framework: FG-cloud

• Sites:
  • OpenStack: @LAL, @CCIN2P3, @IPHC, @LUPM, @Lille, @LPC Clermont
  • CloudMIP: OpenNebula@IRIT
• Sites in agreement with EGI-cloud (European Grid Infrastructure) : @IPHC
• Goals:
  • Common disk image catalogue.
  • Distributed persistent storage.
  • Interware (between user and infrastructure): VM-DIRAC and SlipStream.
