collaboration of upstream and downstream industry chain; and how to distinguish the
boundary of public and private clouds, are the facets that require serious
considerations when enterprises or organization decide to move toward the cloud.

Changes in management process
:
The application of cloud computing is bound to impact the traditional IT management
model. The degree of influence will vary depending on the extent of the use of cloud
applications. The impact is not limited to the IT department but span the organization,
positions, responsibilities, processes, mechanisms, and technologies. For example,
the originally internally controlled elements such as the service on-line time, response
time, and troubleshooting time, will need to be defined and assured in the cloud
service SLA. Therefore, when migrating to the cloud environment, enterprises or
organizations should conduct comprehensive management process impact
assessment to all departments.

Security issues in cloud service
:
Security issue is a great concern when migrating to the cloud. Currently, the security
concerns are present when the enterprise or organization outsources its IT resources
and service applications to the cloud service provider. It is almost impossible for it to
monitor the details of the IT resources and application services. When using the cloud
service provider, the security of the data of the enterprises or organizations, or their
users or clients cannot be guaranteed. The cloud service providers, in protecting their
own trade secrets and security, are shielding the enterprises or organizations from
getting critical security information. Except for the “Personal Data Protection Act”
launched in Taiwan and the “Information security related regulations for the
government agencies” released by the office of the National Information and
Communication Security Taskforce (NICST), no concrete laws and regulations related
to cloud computing operation management were introduced by both sides of the Strait,
thus responsibilities are difficult to be accounted for. Therefore, the enterprises or
organizations, based on their own needs, should assess the potential security risks
brought on by cloud computing applications.

Continuity and migration issues of cloud services
:
There is a significant difference in the continuity and migration of the software asset
management between cloud and traditional services. When an enterprise or
organization discontinues the use of cloud services or changes cloud service
providers, issues will be present in how to continue cloud applications and services,
and extending the data generated by cloud services. For example, how to retrieve the
data generated in the duration of cloud service, which is the asset of the enterprise or
the organization? When retrieved, how to use the data without a cloud platform, or
how to transfer the data onto another cloud service platform. These are all issues
