2 Marks Q & A

UNIT I

1. List out the advantages and disadvantages of cloud servicedevelopment.

Advantages of Cloud Service Development:

One of the advantages of cloud development is that of economy ofscale.

The application can utilize the full resources of the cloud, if neededwithout requiring a company to invest in similar physical resources.

Instead of purchasing or licensing physical copies of software programs

(one for each desktop), cloud applications are typically rented, priced

on a per-user basis. All management activities are managed from a central location rather

than from individual sites or workstations.

For developers, its also easier to upgrade a cloud application than withtraditional desktop software.

Disadvantages of Cloud Service Development:

Web-based applications have long been considered potential securityrisks. For this reason, many businesses prefer to keep their applications,data, and IT operations under their own control.

There have been few instances of data loss with cloud-hostedapplications and storage.

Another potential disadvantage is what happens if the cloud computinghost goes offline.

2. Classify Cloud Service Development

Software as a service(SAAS)

Infrastructure as a service(IAAS) / Hardware as a service(HAAS)

Platform as a service(PAAS)

Database as a service(DAAS)

3. Define Software as a service.

With SaaS, a single application is delivered to thousands of users from

the vendors servers.

Customers dont pay for owning the software; rather, they pay for usingit. Users access an application via an API accessible over the web.

2/24

4. Define Platform as a service.

The development environment is offered as a service.

The developer uses the building blocks of the vendors developmentenvironment to create his own custom application.

Its kind of like creating an application using Legos; building the app ismade easier by use of these predefined blocks of code, even if theresulting app is somewhat constrained by the types of code blocksavailable.

5. Define Hardware as a service.

Hardware as a Service (HaaS) is the next form of service available incloud computing.

Where SaaS and PaaS are providing applications to customers, HaaSdoesnt. It simply offers the hardware so that your organization can putwhatever they want onto it.

Rather than purchase servers, software, racks, and having to pay for

the datacenter space for them, the service provider rents thoseresources.

6. Define Database as a service. The idea behind DaaS is to avoid the complexity and cost of running

your own database.

The database can be integrated with your other services to providemore value and power. For instance, you can tie it in with calendars,email, and people to make your work more powerful.

7. Define Web service.

A web service is an application that operates over a networktypically,over the Internet. Most typically, a web service is an API that can be

accessed over the Internet. The service is then executed on a remote system that hosts the

requested services.

8. What is meant by On Demand Computing?

On-demand computing packages computer resources (processing,storage, and so forth) as a metered service similar to that of a publicutility.

In this model, customers pay for as much or as little processing andstorage as they need.

Clients of on-demand computing services essentially use these servicesas offsite virtual servers. Instead of investing in their own physicalinfrastructure, a company operates on a pay-as-you-go plan with acloud services provider.

9. List out Cloud Service Development Tools.

Amazon

Google App Engine

IBM

Salesforce.com

10. Define Cloud Computing.

The cloud is a large group of interconnected computers. Thesecomputers can be personal computers or network servers; they can bepublic or private.

Example, Google hosts a cloud that consists of both smallish PCs and

7/28/2019 CC 2 Marks Unit 1 - 5

3/24

larger servers. Googles cloud is a private one (that is, Google owns it)that is publicly accessible (by Googles users).

11. What is not Cloud Computing?

Cloud computing isnt network computing. With network computing,applications/documents are hosted on a single companys server andaccessed over the companys network. Cloud computing encompassesmultiple companies, multiple servers, and multiple networks.

Cloud computing also isnt traditional outsourcing, where a company

farms out (subcontracts) its computing services to an outside firm.While an outsourcing firm might host a companys data or applications,those documents and programs are only accessible to the companysemployees via the companys network, not to the entire world via theInternet.

12. List six key properties of cloud computing according to Google'sperspective.

Cloud computing is user-centric.

Cloud computing is task-centric.

Cloud computing is powerful. Cloud computing is accessible.

Cloud computing is intelligent.

Cloud computing is programmable.

13. List out some examples of Cloud Computing ApplicationGoogle family of applications

Google Docs & Spreadsheets

Google Calendar

Gmail

Picasa.

14. What is meant by Cloud Storage?

With cloud storage, data is stored on multiple third-party servers, ratherthan on the dedicated servers used in traditional networked data storage.

When storing data, the user sees a virtual serverthat is, it appears as ifthe data is stored in a particular place with a specific name. But thatplace doesnt exist in reality.

In reality, the users data could be stored on any one or more of thecomputers used to create the cloud.

15. What is meant by Cloud Services?

Any web-based application or service offered via cloud computing is

called a cloud service.

Cloud services can include anything from calendar and contactapplications to word processing and presentations.

With a cloud service, the application itself is hosted in the cloud.

16. Who benefits from cloud computing?

Collaborators.

Road warriors. Cost Conscious user.

Cost conscious IT departments

User with increasing needs.

17. Who shouldn't use cloud computing?

7/28/2019 CC 2 Marks Unit 1 - 5

Social issues

19. What are the three sizes of virtual server offered by Amazon?

Small, which offers the equivalent of a system with 1.7GB ofmemory,160GB of storage, and one virtual 32-bit core processor.

Large, which offers the equivalent of a system with 7.5GB of

memory,850GB of storage, and two 64-bit virtual core processors.

Extra large, which offers the equivalent of a system with 15GB ofmemory,1.7TB of storage, and four virtual 64-bit core processors.

20. List out the features of Google App

Dynamic web serving

21. What is blue cloud? IBM is targeting small- and medium-sized businesses with a suite of

cloud-based on-demand services via its Blue Cloud initiative.

Blue Cloud is a series of cloud computing offerings that enables

enterprises to distribute their computing needs across a globallyaccessible resource grid.

22. List out the features of Sales.force.com.

Salesforce provides its own Force.com API and developers toolkit.Pricing is on a per log-in basis. Supplementing Force.com is

AppExchange, a directory of web-based applications. Developers can use AppExchange applications uploaded by others,

share their own applications in the directory, or publish privateapplications accessible only by authorized companies or clients.

23. Distinguish: Public Cloud Vs Private Cloud

Public cloud is used as a service via Internet by the users, whereas aprivate cloud, as the name conveys is deployed within certainboundaries like firewall settings and is completely managed andmonitored by the users working on it in an organization.

Users have to pay a monthly bill for public cloud services, but in private

cloud money is charged on the basis of per Gb usage along withbandwidth transfer fees.

Public cloud functions on the prime principle of storage demandscalability, which means it requires no hardware device. On thecontrary, no hardware is required even in private cloud, but the datastored in the private cloud can only be shared amongst users of an

7/28/2019 CC 2 Marks Unit 1 - 5

organization and third party sharing depends upon trust they build withthem. It is also entirely monitored by the business entity where it isrunning.

UNIT-II

1.What is the use of web based scheduling?

Everyone places their schedule in the cloud, which then enables themeetings organizer to easily see whos available when.

The cloud-based app finds the best time for all involved and schedules the

We can also benefit from web-based project management applications.

The marketing materials themselves can be created using web-based

word processing applications. This puts the draft materials on the web, for everyone on the team to

see, comment on.

8.How cloud computing is useful for collaborating on budgets?

Cloud computing offers a better approach by working on separatespreadsheets that are later consolidated by creating a single budgetdocument for all departments on the web.

Each department head enters his own budget data.

The rolled-up budget is then created in real-time. When the user needsto slash certain expenditures, those changes are immediately reflectedin the sections or pages for each individual department.

Online budgeting can be accomplished with a simple web-based

spreadsheet, such as Google Spreadsheets, etc

Collaborating on reports:

With one of the applications like google docs or zoho writer, everyonecontributing to the report can access the same master document, onlineand in real time.

When someone from one department adds his section to the document,all the other staffers immediately see the update.

The users can then work on their own sections of the report, logging into the master document via their web browsers. When all the individual

sections are complete, the project leader then looks at the document asa whole, editing for consistency and making sure that all appropriatedata is included.

Collaborating on Expense Reports:

A better solution offered by web based application is that manycompanies have employees from any location can access the website toenter their expense.

The web-based expense report gets electronically circulated to everyonewho needs to approve it .

Another benefit is that user can quickly and easily ensure that all

employees follow the companys rules and regulations by adding theown rule base into the applications management console, andemployees will have to follow the companys policies when enteringtheir expenses.

Most popular web-based expense reporting applications include Concur,ExpensePoint, TimeConsultant.

10.How cloud computing is useful for collaborating on presentation?

Cloud computing makes collaborating on presentations by creating asingle presentation document.

User need not worry about consolidating information from multipledocuments as that the document is located in the cloud, any contributorcan edit directly into the master document from any web browser.

The project leader controls the look and feel of the presentation by

applying a universal style or theme.

The most-used web-based presentation program today is GooglePresentations, Preezo, Zoho Show.

There are multiple ways to communicate online. The following are some of thebest way of talking online.

E-mail

Instant messaging

Web conferencingE-mail: Email is better than instant messaging for communicating longer, morecomplex, and more formal messages.

Instant messaging:Instant messaging is ideal for very short, very immediate messages. Infact, most instant messaging systems limit the length of the messages you cansend through their systems.

If we want to compare each method of online communication with itsoffline equivalent, email is the online version of written letters and instantmessaging is the online version of paging.

Web conferencing: Webconferencing tool is the online equivalent of a group meeting. Itsnot a one-to-one communication, but rather a one-to-many presentation or

many-to-many conversation. Web conferencing is a way to facilitatecommunications among all the members of the group even if the group is spreadout between a dozen or more locations.

1. What is cloud storage?

Cloud storage involves exactly storing the data with a cloud serviceprovider rather than on a local system.

The data stored on the cloud, hosted on third party servers, can beaccessed via an Internet link. Hosting companies operate large datacentres, and people who require their data to be hosted buy or lease

storage capacity from them. The data center operators virtualize the resources according to the

requirements and expose them as storage pools, which the customers canthemselves use to store files or data objects.

The resource may span across multiple servers.

2. What are the primary benefits of using cloud storage?

Data stored on a cloud can be accessed from any location via the internet.This makes it especially appealing to road warriors.

Workers dont need to use the same computer to access data nor do they

have to carry around physical storage devices. Cloud is secure form accidental erasure or hardware crashes because it is

duplicated across multiple physical machines.

Virtual resources in the cloud are typically cheaper than dedicated physicalresources.

Cloud storage providers balance server loads and move data among
