  • 1. ODCA U: INTEROP ACROSS CLOUDSCa therine S pence, Intel ITPankaj Fichadia, National AustraliaBa nk
  • 2. AGENDA Interop Usage Models• Interoperability Across Clouds• VM Interop• PaaS Interop• Long Distance Migration (LDM)• SaaS Interop• Commercial Framework Key Take-aways Information and assets Questions2
  • 3. INTEROP USAGE MODELS1. InteroperabilityAcross CloudsIaaS:Moving SystemsPaaS:Moving AppsSaaS:MovingCapabilities4. Long Distance Migration(LDM)2. VM Interop 3. PaaS Interop 5. SaaS Interop6. Commercial Framework3
  • 4. 1. INTEROPERABILITY ACROSS CLOUDS Cloud apps & services must co-exist and interactwith one another and non-cloud systems, for:• Rapid adoption of cloud services by cloud subscribers• Ability to combine cloud services from multiple providers Perspectives:• Portability = serial process of moving from one environment to another• Interconnectability = parallel process to communicate and interact4
  • 5.  Key points:• Requires an open and complete transportation path – reserve resources at target• Sufficiently like environment at target & source to effect the transfer• UM contains MoSCoW prioritization of requirements• Providers must support common standards, and subscribers must understand and alignto these standards (and ask for them)2. VM INTEROP Scenarios:• Check interop• Move/copy between 2 clouds• Leverage common operation Relevant Standards:• Packaging - DMTF OVF• Catalog - CIMI• Provisioning – SMPL, OASIS CIMIMigrate live or with downtime5
  • 6. 3. PAAS INTEROP Scenarios:• Rapid app on-boarding• Configure PaaS environment• App scalability (auto scale)• Operation & monitoring• App porting Key points:• No modification of the app is required to execute it within PaaScontainers as the app is deployed to multiple providers• PaaS is constrained to deploying a single application developed for aspecific programming language within a hosted application container• Assumes data as a service or database as a service is in effect6
  • 7. 4. LONG DISTANCE MIGRATION (LDM) Groups of usagescenarios:• Relocate• Extend• SustainLayer Scope RelevantStandards3.

  • 8. 5. SAAS INTEROP Scenarios:• Service configuration• Bulk data transfer• Real time data access• Service aggregation• Service transfer Key points:• Service Catalog & self-service provisioning/configuration• Automation & web services to enable data exchange• Subscriber owns their data and can export via self-service• Porting involves end of life at source and new service at target• No relevant industry standards for service transfer8
  • 9. 6. COMMERCIAL FRAMEWORK Scenarios:• Cloud service provider selection• Contract negotiation• Ongoing use and transfer• Termination and reversetransition Key points:• Contractual obligations should consider specific drivers:• Service and Data Location• Intellectual property• Software Entitlement ManagementBusinessrequirementsRegulatorydriversCommercialdriversCommercial FrameworkServices Agreement/ Contract• Control environment• Data management, movement, return• Security, Privacy, Availability, Recoverability9

Growing need for open, multi-vendor and interoperablesolutions for all Cloud Computing service modelsCollection of ODCA usage models describe interoperability &cloud service selection, negotiation, use and terminationlifecycleInteroperability includes portability and interconnectabilityperspectivesBig opportunity for standards and automationsolutions, especially moving up the stack with morecomplex IaaS, PaaS and SaaSKEY TAKE-AWAYS FROM THESE UM’S10
