Conclusion: A majority of organisations around the world and across Australia are implementing or trialling some form of Cloud service whether it be IaaS, PaaS or SaaS. While Cloud services offer many potential benefits to organisations they can increase complexity in a number of areas of IT service management. Organisations may implement a hybrid Cloud model and deliver some services using public or private Cloud.
Business areas may subscribe to Cloud services for the provision of application services with or without the participation of IT. Identifying and managing the schedule of change with a wide variety of providers can be complex but will provide the CIO and the organisation with a clear view of who, what, when, and how changes will be made, the risks involved and the mitigation actions required.
