Note: Answer all questions. Kindly note that answers for 10 marks questions should be approximately of 400 words. Each question is followed by evaluation scheme.

1 List and explain the services of cloud computing.

Answer: Cloud computing, often referred to as simply “the cloud,” is the delivery of on-demand computing resources—everything from applications to data centres—over the Internet on a pay-for-use basis. Cloud computing is a recently evolved computing terminology or metaphor based on utility and consumption of computing resources. Cloud computing involves deploying groups of remote servers and software networks that allow centralized data storage and online access to computer services or resources. Clouds can be classified as public, private or hybrid.

Software as a service (SaaS):

2 List the areas of the organization which has the effect of cloud computing and explain any two.

Answer: Cloud computing is more than an advance in technology. It represents transformation for your entire organization — people, processes, and systems.

Finance — Identifying cloud services and analyzing accounting models will help your organization determine how to proceed most efficiently and effectively with activities such as research and development and revenue recognition.

Internal audit — In order to accommodate the move to cloud computing, cloud service providers will need to modify, upgrade, or replace systems to process, measure, and control use. This will also be critical for billing. Providers should have the right SLAs in place, and a process to monitor those SLAs. Buyers of cloud services must give themselves the same control and monitoring environment in the cloud that they did on internal networks and servers. This is much more challenging, as your organization no longer controls hardware. Methods of application management may change significantly.

3 Explain the different Software clients.

Answer: There is different software clients discussed below:

Shareware: This software is downloadable from the Internet. Licenses differ, but commonly the user is allowed to try the program for free, for a period stipulated in the license, usually thirty days. At the end of the trial period, it must be purchased or uninstalled. Some shareware incorporates an internal clock that disables the program after the trial period unless a serial number is supplied. Other shareware designs continue to work with "nag" screens, encouraging the user to purchase the program.

4 Explain the different types of data controls in cloud.

Answer: Controls on data in the cloud computing environment include the governance policies set in place to make sure that your data can be trusted. The integrity, reliability, and confidentiality of your data must be beyond reproach. And this holds for cloud providers too.

For example, assume that you’re using a cloud service for word processing. The documents you create are stored with the cloud provider. These documents belong to your company and you expect to control access to those documents. No one should be able to get them without your permission, but perhaps a software bug lets other users access the documents. This privacy violation resulted from a malfunctioning access control. This is an example of

5 Explain (a) Open Cloud Consortium (OCC) (b) Open Grid Forum (OGF).

Answer:

(a) Open Cloud Consortium (OCC) :The Open Cloud Consortium (aka OCC) is a 501(c)(3) non-profit venture which provides cloud computing resources to support "scientific, environmental, medical and health care research." OCC manages and operates resources including the Open Science Data Cloud (aka OSDC), which is a multi-petabyte scientific data

(b) Open Grid Forum (OGF): The Open Grid Forum (OGF) is a community of users, developers, and vendors for standardization of grid computing. It was formed in 2006 in a merger of the Global Grid Forum and the Enterprise Grid Alliance. The OGF models its process on the Internet Engineering Task Force (IETF), and produces documents with many acronyms such as OGSA, OGSI, and JSDL.

The OGF has two principal functions plus an administrative function: being the standards organization for grid computing, and building communities within the overall grid community (including extending it within

6 What are the most popular cloud applications?

Answer: Cloud computing, often referred to as simply “the cloud,” is the delivery of on-demand computing resources—everything from applications to data centres—over the Internet on a pay-for-use basis.

Adobe Connect - Video conferencing software:Adobe Connect, one of the Acrobat.com services, is a great way to share ideas, discuss details, and complete work with others - all online. There's no installation required, so getting started is easy
