The goal of SLM is to maintain and improve
IT service quality through a constant cycle of
agreeing, monitoring, reporting and reviewing
IT service achievements (Maestranzi
et al.
, 2002,
Gatial et al., 2008). The SLM process is respon-
sible for ensuring the service level agreements and
any underpinning operational level agreements
(OLAs) or contracts are met, and for ensuring that
any adverse impact on service quality is kept to
a minimum. The process involves assessing the
impact of changes upon service quality and SLAs,
both when changes are proposed and after they
have been implemented. Some of the most impor-
tant targets set in the SLAs will relate to service
availability and thus require incident resolution
within agreed periods.
of business opportunities, mutual understanding
and trust among service recipients and providers.
Using the utility computing model, grid aims
at provisioning the virtualized services, that must
adhere to the set of standards ensuring interoper-
ability, access and common acceptance within
the community of beneficiaries of IT resources'
virtualization. The benefits of virtualization cover
more effective utilization of common IT resources,
common access to more resources with unique
capabilities, increase of efficiency of IT resources
utilization, and cost efficiency of IT.
Grid computing or private cloud computing
are about controlled sharing. Resources owners
want to enforce policies that constrain access
according to group membership and abilities to
pay. The grid computing and cloud computing
are technologies not yet mature. That innovations
development should be accompanied by the focus
on business models to support management of the
virtualization processes.
For the last few years, focus on environmen-
tal sustainability issues influences on green IT
concepts, emphasizing the reducton of the envi-
ronmental impact of doing business and the IT
development. Therefore more control over user
activities, cost savings reporting are necessary,
however at first pro-ecological approach should
be implemented in the business strategy manage-
ment process.
FUTURE RESEARCH DIRECTIONS
AND CONCLUSIONS
Sustainability exemplifies the new problem field
for managers and corporate leaders: an emerging
network-based organizational world where busi-
ness units must maintain consistency of purpose
and identity, although they must be flexible enough
to interact and compete in conditions of constant
change, to share IT resources and to add new
capabilities, to reduce energy consumption and
emissions of harmful substances.
The factors influencing on sustainability are
competences, resources, project management, IT
management, organizational integration, policy
and regulatory framework, business strategies and
conflict resolution abilities. In the IT resources
virtualization networked approach partners (who
may compete in other areas of marketplace) join to
share the resources in the value creation process.
Participating in an IT resources virtualization
network is an increasingly strong motivator for
accessing required capabilities. The customers,
taking into account the observed benefits, are able
to emphasize their requirements concerning the IT
