Status Accounting on

inter-organizational

Service Management

Level

• IT Service Management Perspective

- Specification of inter-organizational IT Service Management (ITSM)

processes influences possible service states, e. g. io-Problem

Management -> State “problem”

- ITSM on intra- and inter-organizational level needs to be aligned

- Orientation on standards like ITIL or ISO 20000 could ease alignment

because of widespread international degree of familiarity

- FM could be modeled according ITIL for CDMB and io-CMDB

• Proposed Standards are developed “Stand-alone”, thus holistic integration

efforts necessary

• Emergence = complex patterns and systems might arise out of a

multiplicity of relatively simple interactions:

- Observable in inter-organizational service scenarios?

- Small cause might have large effect: root cause analysis has to be done

now inter-organizational

• MDR versus CMDB: replace or integrate decision for any MDR necessary

Open Issues

• To enable Status Accounting for hybrid cloud deployments corresponding

tools must enable modeling of organizations (OM), information and it’s

relationships (IM), communication (CM) and functional (FM) aspects

Status Accounting on inter-organizational

Service Management Level

• DMTF’s Virtualization Management (VMAN) standard

- Set of specifications for the management lifecycle of a virtual

environment.

- Open Virtualization Format (OVF): Standard format for

packaging and describing virtual machines and applications for

deployment across heterogeneous virtualization platforms

- VMAN profile: standardize many aspects of the operational

management of a heterogeneous virtualized environment

• DMTF’s Configuration Management Database Federation

(CMDBf) standards:

- Facilitates sharing of information between configuration

management databases (CMDBs) and other management

data repositories (MDRs)

- Enables to federate and access information from complex,

multi vendor infrastructures.

- Simplifies the process of managing related configuration data

stored in multiple CMDBs and MDRs

• UN/CEFACT’s Modeling Methodology (UMM)

- UN/CEFACT = United Nations Center for Trade Facilitation

and Electronic Business

- Information modeling of business requirements of inter-

organizational business processes

- Platform independent

- Core Components Library (CCL): Definition of reusable

building blocks

Challenges:

• Composition of services necessitates multiple different input types for each

service manager.

• Service Asset and Configuration Management for hybrid cloud services

requires Status Mapping both across organizations and across the different

service management levels.

Our Approach: Standards form the basis on all levels

Consolidated life cycle of service

parts:

- Inter-organizational (io) Service

Management Perspective

- Type of states depend on

specified io-Service

management processes, e. g. io-
