  • 1. 1Apache DeltacloudSpeaking EC2 and CIMI to OpenStackDavid LutterkortPrincipal Software EngineerRed Hat, Inc2013-04-18
  • 2. 2Overview● Cloud APIs● What is Apache Deltacloud ?● What is CIMI ?● Deltaclouds EC2 frontend● Using Deltacloud with Openstack● Questions
  • 3. 3Cloud APIs● Wild West – every cloud has one● Material differences● Annoying innovation● de facto standards● EC2: widely used and copied● OpenStack: excellent governance● de jure standards● backed by Standards Developing Organization● CIMI produced by DMTF
  • 4. 4Standard challenges● Build broad community● Allow standards development the open source way● Bring proprietary players into the tent● Governance/licensing● Adaptability● Enable wide range of implementations● Let clients discover variations

  • 8. 8DMTF CIMI● Distributed Management Task Force (DMTF)● Broad industry participation● Produced OVF and CIM● Covers wide range of IaaS objects● Published August 2012● RESTful API● Despite the name, not connected to CIM● CIMI forces Deltacloud to keep state
  • 9. 9CIMI ModelSystems Machines Volumes NetworksCIMI Entry PointSystems Machines Volumes NetworksServers Storage volumesGrouping ofresourcesSystemsMetadata●Flexibility through discovery●Many more supporting resources●including monitoring, events, jobs●Common patterns (Templates, Configs, Images)Networks,routing, ports

  • 12. 12What Deltacloud is doing around CIMI● CIMI frontend● use against various clouds● CIMI client web app● CIMI test suite● CIMI Ruby client (soon)
  • 13. 13Deltaclouds EC2 frontend● Started as POC last spring● Inspired by AWSOME● Used by RHEV-M/oVirt● Basic functionality● Describe images/AZs● Instance lifecycle management● SSH keys
  • 14. 14Openstack support● Nova● Flavors● Regions● Images● Servers/instances● SSH keys● Swift● Cinder● Glance
  • 15. 15Using Deltacloud with Openstack● Start Deltacloud with Openstack driver● Point at Keystone● Users can dynamically switch endpoints● Deployment options● Close to user● Close to Keystone
