4. 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

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 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

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 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

7. 4. LONG DISTANCE MIGRATION (LDM)
 Groups of usage
scenarios:
• Relocate
• Extend
• Sustain
Layer Scope Relevant
Standards
3. Migration Protocol
Procedures, 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

1. Application &
System Management
Software binaries, PaaS application stack, Cloud Broker service or
appliance, monitoring, logging, auditing, licensing, support
CIMI, SPML,
SCIM
0. Base Runtime
Virtual appliance including system configurations, additional metadata,
session related data
OVF

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 transfer
8

9. 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
Regulatory
drivers
Commercial
drivers
Commercial Framework
Services Agreement/ Contract
• Control environment
• Data management, movement, return
• Security, Privacy, Availability, Recoverability

10. 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
