3. Conclusion
Introduction
-
Access to a shared pool of configurable computing resources
- Access to needed infrastructure, service, or applications
Brief functions of Cloud Computing
Introduction
-
Software-as-a-Service (SaaS) enables the user to use applications running on a cloud infrastructure from a provider
-
Platform-as-a-Service (PaaS) provides the users with the capability to create their own services and applications
- Infrastructure-as-a-Service (IaaS) uses virtual machine to provide consumers with storage, networks, processing power, and other important computing resources
Three categories of Cloud Computing
Introduction
-
Discuss information systems management issues with cloud computing
-
Point out the directions the issues may take in the coming five years
- Ensure organizations reap maximum benefit from cloud computing

Ethical Issues
Service providers have an ethical duty to protect data and information stored in their data centers
Security Issues
the problem of Confidentiality
Only an authorized person should have access to the sensitive data
Or it will be exposed to a third party
Security Issues
the problem of Privacy
The control of disclosure of personal information should lies with only the information owner
Security Issues
the problem of Integrity
Only the necessary permissions are given to a user to access to read, modify or update data.
Security Issues
solution for Confidentiality, Privacy and Integrity
Authentication
Security Issues
the problem of Availability
The system should continue working without any interruptions
even when there is a breach of security or an internet breakdown
Security Issues
solution for Availability
Improvement of Firewalls and Internet hardware.
Legal and Jurisdictional Issues
problem
There is a possibility of data centers being located in locations with different jurisdiction
solution
Law makers of different countries have been gathered to discuss a standard law pertaining to this problem.
Legal and Jurisdictional Issues
Data lock in
problem
The lack of standardization of API for cloud computing
This may cause users to have a hard time moving data from one service provider to another
solution
Service provider work together towards a standardized API
to help organizeation to migrate their data and applications easily
Data lock in

Energy management,
problem
No standardized resources such as execution time , inbound bandwidth, outbound bandwidth, CPU cores, and processor type
Lack of standardized service level agreements
Users or organizations should be more aware of
the detailed services given by the service providers
This will be solved by the provision of a more holistic
service in the future.
solution
Lack of standardized service level agreements
problem
The desire of pursuing for uniqueness may not be satisfied, as a service provider has more than one client.
Customization
solution
Due diligence on communication and mutual understanding between users and service providers is required
Customization
problem
The upgrading of existing technologies will involve
buying of new ones to replace the old ones
It's hard to strike a balance between being efficient and economical
Technology bottleneck
The upgrading of existing technologies will be cheaper
and easier in the future.
solution
Technology bottleneck
problem
With the emerge of Cloud Computing, the size of IT department will be downsized, which may in turn undermine the morale in the company and the quality of service.
Strategy issues
solution
Organizations will have to trade off and come up with adequate changes

Energy management,
problem
Organization will find it hard to determine which of their data should be moved in the cloud and which should remain on the organisations traditional system
Implementation Issues
Using stardardized API so the in-house data and applications can be merged together.
solution
Implementation Issues
problem
The reputation of an organization will be jeopardized
if it shares the same resources with other organizations with a bad reputation
Reputation Fate Sharing
No solutions so far
solution
Reputation Fate Sharing
problem
Cloud computing will be affected if Internet goes down, and there is no alternative for internet.
Dependence on Internet
solution
Dependence on Internet
No solutions so far
problem
There is no guarantee of the service provider to commit to high quality of service
Quality of Service
Service level agreement(SLA) for cloud computing
should be standardized
solution

problem
Information on could service provider are not disclosed, leading to the loss of customers' trust
Transparency
They should provide their security policies, design, practices, and relevant security measures in their daily operations
solution
Transparency
problem
Data centers consume high amounts of energy, and the cost of powering and cooling is the major expenditure
Energy Management
The use of proper workload management and
energy saving technologies like virtualisation
solution
Energy Management
problem
Data will be lost if a disaster happens
Disaster recovery
Put data backup in place and incorporate it into the SLA
solution
Disaster recovery
problem
Employees of a service provider may cause a security breach, as he or she has access to data or services which may be exposed to an unauthorised third parties
Malicious insider
Service providers should include appropriate remedies in the employment contract
solution
Malicious insider
Conclusion
This paper provides
an overview of management issues with cloud computing, the limitations and the management issues, and the
guidelines to assist management in Cloud Computing
