INTEROP USAGE MODELS
1. InteroperabilityAcross Clouds
IaaS:Moving Systems
PaaS: Moving Apps
SaaS:Moving
Capabilities
4. Long Distance Migration (LDM)
2. VM Interop 3. PaaS Interop 5. SaaS Interop
6. Commercial Framework

1. INTEROPERABILITY ACROSS CLOUDS Cloud apps & services must co-exist and interact with 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 interact
4
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 align
to 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 CIMI
Migrate live or with downtime
5
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 PaaS
containers as the app is deployed to multiple providers• PaaS is constrained to deploying a single application developed for a
specific programming language within a hosted application container• Assumes data as a service or database as a service is in effect

4. LONG DISTANCE MIGRATION (LDM)Cloud
Subscriber (Consumer)
Source Cloud Target Cloud
Service MovementDistance >20km
Source Cloud Provider
Target Cloud Provider
System System
Groups of usage scenarios:• Relocate• Extend• Sustain
Layer Scope Relevant Standards
3. Migration ProtocolProcedures, processes, methodologies and checklists including Start/Halt/Ack/Stop/Failure/Finish
None
2. Business; Non-functional
Appliance metadata, disaster recovery, high availability, advance security configurations, compliance requirements, automated scaling parameters, carbon footprint requirements
TOSCA
1. Application & System Management
Software binaries, PaaS application stack, Cloud Broker service or appliance, monitoring, logging, auditing, licensing, support
CIMI, SPML, SCIM
0. Base RuntimeVirtual appliance including system configurations, additional metadata, session related data
OVF

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 transfer
8
6. COMMERCIAL FRAMEWORK
Scenarios:• Cloud service provider selection• Contract negotiation• Ongoing use and transfer
• Termination and reverse transition
Key points:• Contractual obligations should consider specific drivers:
• Service and Data Location• Intellectual property• Software Entitlement Management
Business requirements
Regulatorydrivers
Commercialdrivers
Commercial Framework
Services Agreement/ Contract
• Control environment• Data management, movement, return• Security, Privacy, Availability, Recoverability

Growing need for open, multi-vendor and interoperable solutions for all Cloud Computing service models
Collection of ODCA usage models describe interoperability & cloud service selection, negotiation, use and termination lifecycle
Interoperability includes portability and interconnectability perspectives
Big opportunity for standards and automation solutions, especially moving up the stack with more complex IaaS, PaaS and SaaS
