INTEROP USAGE MODELS

1. InteroperabilityAcross Clouds

IaaS:Moving Systems

PaaS: Moving Apps

SaaS:Moving

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

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

9

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
