computing, will be the core and essence of success after the introduction of cloud computing.
In order to establish more effective governance models, enterprises and organizations
should stand ready to respond to the changes and challenges in the cloud environment:
1.
Change of decision-makers and decision-making
:
The mechanism of IT decision-making in an enterprise or organization aims to solve
two problems: “What decisions need to be made?” and “Who should make them?”
The ownership and responsibility of decision-making is often relying on different
stakeholders, as well as depending on various types of decision-making entities,
including business-oriented, IT-oriented, decentralized, centralized, and IT
business balanced. Different from the traditional distributed and centralized IT
decision-making models, the decision-making in a cloud framework is separated
based on operation characteristics, information applications, and demands of
information resources. As to how to separate the decision-making to ensure the
compatibility of the cloud computing infrastructure and IT decision-making
mechanism is the key consideration for enterprises migration to the cloud.
2.
Cost of Migrating to the cloud
:
Though lowering costs is the key incentive of moving to cloud computing, it may
mean that there is a short-term cost increase. Some of the costs are difficult to predict
at an early stage, especially the hidden costs, such as the direct and indirect costs
replacing the existing system to public cloud. There is a need to consider operation
application requirements and the agility as well as relevance of cloud services, to
assess if all systems are suitable for cloud computing, and to evaluate the costs and
benefits including its hidden costs in system integration. At this time, integrating the
software from different cloud service providers is still challenging. These migration
costs may not reduce the value of enterprise cloud computing applications, but it will
affect the overall cost-effectiveness of the short and long-term cloud services.
Therefore, enterprise using cloud computing to reduce costs must pay more attention
to issues like cloud data, applications, and system integration.
3.
Framework of cloud computing
:
To ensure solid cloud implementation, beyond the equipment and resources to
establish the cloud infrastructure, the wants and needs of the clients and users should
be the first priority. The need for individualization in enterprises and organizations is
intensifying. But relatively speaking, cloud service providers’ differentiation capability
is weak and is lacking of customized features. Thus, how to balance the personalized
applications for the enterprise and organizations to the needs of the centralized
resource/platform; how to address the cloud computing IT resource utilization and
system implementation, data and application integration; how to facilitate the
