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.

Q 1 What are the services of cloud computing? Explain.

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):

Cloud-based applications—or software as a service (SaaS)—run on distant computers “in the cloud” that are owned and operated by others and that connect to users’ computers via the Internet and, usually, a web browser.

Q2 Write a note on “Software as a Service.

Answer: Software as a Service (SaaS) is a software distribution model in which applications are hosted by a vendor or service provider and made available to customers over a network, typically the Internet.

SaaS is becoming an increasingly prevalent delivery model as underlying technologies that support Web services and service-oriented architecture (SOA) mature and new developmental approaches, such as Ajax, become popular. Meanwhile, broadband service has become increasingly available to support user access from more areas around the world.

Q3 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.

Q4 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.

Q5 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 sharing resource. The consortium is based in Chicago, Illinois, and is managed by the 501(c)3 Center for Computational Science Research.

Partnerships and engagements:

Q6 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 - and free

Animoto - Video software:Turns still photos, music and videos into video presentations; similar to VoiceThread

Blogger - Google blogging software:Blogging is about more than
