3. TOPIC & UM BACKGROUND
The ODCA Contributor organisations have created this UM to collaboratively identify how
cloud services should be considered for interoperability, and so as to then provide this as
a clear framework to the Cloud Provider and ISV community, and to share with the
general Cloud consumer.
The Interoperability UM’s address:
1. Concept
2. Usage Scenario’s
3. Important enabling elements
4. Categorisation of service qualities in context of the UM
Applicable Usage Models (UM’s)
1. VM Interoperability
2. Long Distance Migration

4. UM CORE – KEY ELEMENTS
USAGE
SCENARIOS
Define the specific usage scenario, and the associated parameters to take
into account
IDENTIFY THE
INTEROP
ELEMENTS
Functional: System, Network, Storage, Access
Non-functional: SLA’s, KPI’s, Compliance, Responsibility, Service transfer or
share
STANDARDS &
SPECIFICATIONS
Identify applicable standards & specifications at each layer to package for
interoperation
CATEGORISE
SERVICES
Categorise service requirements – bronze, silver, gold, platinum
Categorise service offering via catalogue – bronze, silver, gold, platinum

2. Tooling (Enterprise vs Public tools)
3. Used 2012 Software versions = point in time baseline (approximately 25% success against UM)

9. OWNERSHIP &
RESPONSIBILITY
Ownership, Service Transfer Point, Federated responsibility
DATA
MANAGEMENT
Master record management & co-ordination
SECURITY Bridging cloud providers and your enterprise security
KPI’S
Target service selection and measuring (cost, quality, functionality,
comparability, business requirements), Usage Scenario related
measurements, Carbon credits
UM CORE – IMPORTANT CONSIDERATIONS
Forecast 2013 VMInterop & LDM U-Track | 9
10. Identify and integrate standards into tooling: OVF (Open Virtualisation Format) , CIMI,
(Cloud Infrastructure Management Interface ), SPML (Service Provision Markup Language),
SCIM (System for Cross Domain Identity Management ) , TOSCA (Topology and
Orchestration Specification for Cloud Applications). The current OVF Specification does not
enable Service Providers to establish mature interoperability
STANDARDS &
SPECIFICATIONS
NEUTRAL TOOLING Niche for Neutral ISV’s to create interop tooling
CONSIDER ODCA
UM’S
Use the ODCA UM’s when developing products – the ISV’s are “generally” still establishing
their products, and in the defensive development phase. Participating in UM creation is a
chance to influence that development
CATEGORISE
PRODUCTS &
SERVICES
Categorise the functionality of products and services – gold, silver, bronze, platinum
KEY INDUSTRY ACTIONS (STANDARDS AND MORE)
Forecast 2013 VMInterop & LDM U-Track | 10
11. KEY TAKE-AWAYS FROM THESE UM’S
Brokers require proprietary agents at source and target – limits options
and locks services in
Be clear on Business requirements and objectives – define service
parameters very clearly
The industry is developing fast, but at an early stage – each product
mostly works as advertised (products and services) – those features not
advertised, don’t work
Consumer has overall responsibility – splitting workloads and migrating
systems emphasize this
