Introduction

• Access to a shared pool of configurable computing resources
   
• Access to needed infrastructure, service, or applications 

Brief functions of Cloud Computing

Introduction

1. Software-as-a-Service (SaaS) enables the user to use applications running on a cloud infrastructure from a provider
    
2. Platform-as-a-Service (PaaS) provides the users with the capability to create their own services and applications 
    
3. 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

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

Transparency,

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

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
