UNIT I

1. List out the advantages and disadvantages of cloud service development.

Advantages of Cloud Service Development: One of the advantages of cloud development is that of economy of scale. The application can utilize the full resources of the cloud, if needed—without 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, it’s also easier to upgrade a cloud application than with traditional desktop

software.

Disadvantages of Cloud Service Development: Web-based applications have long been considered potential security risks. 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-hosted applications and storage. Another potential disadvantage is what happens if the cloud computing host 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 vendor’s servers. Customers don’t pay for owning the software; rather, they pay for using it. Users access an

application via an API accessible over the web.

4. Define Platform as a service. The development environment is offered as a service. The developer uses the “building blocks” of the vendor’s development environment to create

his own custom application. It’s kind of like creating an application using Legos; building the app is made easier by use of

these predefined blocks of code, even if the resulting app is somewhat constrained by the types of code blocks available.

5. Define Hardware as a service. Hardware as a Service (HaaS) is the next form of service available in cloud computing. Where SaaS and PaaS are providing applications to customers, HaaS doesn’t. It simply

offers the hardware so that your organization can put whatever they want onto it. Rather than purchase servers, software, racks, and having to pay for the datacenter space

for them, the service provider rents those resources.

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 provide more 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 network—typically, 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 public utility. In this model, customers pay for as much or as little processing and storage as they need. Clients of on-demand computing services essentially use these services as offsite virtual

servers. Instead of investing in their own physical infrastructure, a company operates on a pay-as-you-go plan with a cloud 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. These computers can be personal

computers or network servers; they can be public or private. Example, Google hosts a cloud that consists of both smallish PCs and larger servers.

Google’s cloud is a private one (that is, Google owns it) that is publicly accessible (by Google’s users).

11. What is not Cloud Computing? Cloud computing isn’t network computing. With network computing, applications/documents

are hosted on a single company’s server and accessed over the company’s network. Cloud computing encompasses multiple companies, multiple servers, and multiple networks.

Cloud computing also isn’t traditional outsourcing, where a company farms out (subcontracts) its computing services to an outside firm. While an outsourcing firm might host a company’s data or applications, those documents and programs are only accessible to the company’s employees via the company’s network, not to the entire world via the Internet.

12. List Six Key properties of cloud computing according to Google's perspective. 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, rather than on the

dedicated servers used in traditional networked data storage. When storing data, the user sees a virtual server—that is, it appears as if the data is stored in

a particular place with a specific name. But that place doesn’t exist in reality. In reality, the user’s data could be stored on any one or more of the computers 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 contact applications 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? Security conscious Internet impaired Offline workers Anyone married to existing application.

18. What are the barriers to use and adopt web based applications? Technical issues. Business model issues Internet issues Security issues Compatibility issues 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 of memory,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 of memory,1.7TB of storage,

and four virtual 64-bit core processors.

20. List out the features of Google App Dynamic web serving Full support for all common web technologies Persistent storage with queries, sorting, and transactions Automatic scaling and load balancing APIs for authenticating users and sending email using Google Accounts.

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

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 globally accessible resource grid.

22. List out the features of Sales.force.com. Salesforce provides its own Force.com API and developer’s 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 private applications accessible only by authorized companies or clients.

UNIT-II

1.What is the use of web based scheduling? Everyone places their schedule in the cloud, which then enables the meeting’s organizer to easily

see who’s available when. The cloud-based app finds the best time for all involved and schedules the meeting. Web-based scheduling programs schedule both in-person meetings and teleconferences with

attendees from multiple locations. It allows to work with the schedules of people around the country and even in different firms.

2.List out some of the web based scheduling applicationsgoogle calendaryahoo calendarwww.appointmentquest.comwww.hitappoint.comwww.schedulebook.com

3.List the benefits of web based contact management Through web based contact management a large list of contacts from any location can be

accessed. It allows to customize the program so that the user can be automatically flagged each day with a list

of accounts to contact (and for what purposes). Some communication can even be automated, via the use of scheduled emails.

The key is that everything is stored and managed in the cloud so that user and their sales manage can access important contact information from anywhere at any time.

4.List out web based contact management application hosted in the cloud.www.bigcontact.comwww.highrisehq.comwww.salesforce.com

5.List out some of the functions useful in the management of group projects in cloud The management of group projects is made easier with the use of a web-based project management

application. Project members can log in from any location to access the project’s master file. they can add or

delete tasks, mark tasks as complete, enter detailed billing information for individual tasks, and so forth.

Many project management applications include additional functions useful in the management of group projects. These features may include group to-do lists, web-based file sharing, message boards, time and cost tracking, and so on.

The most robust of these apps lets manage multiple project simultaneously; users can schedule their time across multiple projects and make sure they’re not doing two things at once.

6. What are the most popular web based project management applications? www.onproject.com

7.How cloud computing is useful for collaborating on marketing materials? When it comes to creating marketing materials, the best approach is to use a combination of web-

based applications. Web-based email facilitates communication between departments. 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 separate spreadsheets that are later

consolidated by creating a single budget document 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 need to slash certain expenditures,

those changes are immediately reflected in the sections or pages for each individual department. Online budgeting can be accomplished with a simple web-based spreadsheet, such as Google

Spreadsheets ,etc...

9.How cloud computing is useful for collaborating on preparation of reports and expense reports?

Collaborating on reports: With one of the applications like google docs or zoho writer, everyone contributing to the report can

access the same master document, online and 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 in to the master document via

their web browsers. When all the individual sections are complete, the project leader then looks at the document as a whole, editing for consistency and making sure that all appropriate data is included.

Collaborating on Expense Reports: A better solution offered by web based application is that many companies have employees from any

location can access the website to enter their expense. The web-based expense report gets electronically circulated to everyone who needs to approve it . Another benefit is that user can quickly and easily ensure that all employees follow the company’s rules

and regulations by adding the own rulebase into the applications management console, and employees will have to follow the company’s policies when entering their 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 a single presentation document. User need not worry about consolidating information from multiple documents as that the document

is located in the cloud, any contributor can 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 Google Presentations,Preezo,Zoho Show.

This, in turn, facilitates group collaboration which is what large projects are all about.

23. How web based word processors work? Microsoft Word is a software program that is installed on our computer’s

hard disk. Web-based word processors, in contrast, are hosted in the cloud, not on your hard

drives are the documents you create with these applications. And these web-based applications mimic the key features of Microsoft Word, so you don’t give up

much in the way of functionality.

24. What are the benefits of online word processors? Documents can be accessed wherever we are, from any PC. We’ll never discover that the document you need is located on your office PC when you’re at

home or away. Can easily share our documents with other. We can’t lose your work theoretically. Everything we do is saved

on the web. Web-based applications are free as in it costs zero dollars, unlike the ever increasingly expensive

Microsoft Office suite. Being free makes it easy to take for a test drive, and even easier to add to our bag of

applications. These cloud services can perform nearly all of Word’s basic functions, which makes them

perfect for corporate and small business environments.

Live or Streaming video - where full motion webcam, digital video camera or multi-media files are pushed to the audience. VoIP (Real time audio communication through the computer via use of headphones and speakers) Web tours - where URLs, data from forms, cookies, scripts and session data can be pushed to other participants enabling them to be pushed though web based logons, clicks, etc. This type of feature works well when demonstrating websites where users themselves can also participate. Meeting Recording - where presentation activity is recorded on the client side or server side for later viewing and/or distribution. Whiteboard with annotation (allowing the presenter and/or attendees to highlight or mark items on the slide presentation. Or, simply make notes on a blank whiteboard.) Text chat - For live question and answer sessions, limited to the people connected to the meeting. Text chat may be public (echo'ed to all participants) or private (between 2 participants).

7. What is a web conference tool? In a world where we now communicate and collaborate mainly via the Internet, it’s important to have

the right tool available. Not only do you need something that is dependable and works properly, but you also want a tool that is easy for all of your collaborators to use. Having a lot of features is nice, but if the

people you’re trying to communicate with can’t figure out how to join you, more than likely you’ll end up alone!

8. List out most popul ar web conferencing tools. 1.WebEx 2.Tinychat 3.Yugma 4.Twiddla 5.Sync.in 6.Vyew

9. What is best way to talk in online? Why? There are multiple ways to communicate online. The following are some of the best way of talking online.

E-mail Instant messaging Web conferencingE-mail: Email is better than instant messaging for communicating longer,more complex, and more formal messages.Instant messaging: Instant messaging is ideal for very short, very immediate messages. In fact, most instant messaging systems limit the length of the messages you can send through their systems. If we want to compare each method of online communication with its offline equivalent, email is the online version of written letters and instant messaging is the online version of paging.

Web conferencing: Web conferencing tool is the online equivalent of a group meeting. It’s not a one-to-one communication, but rather a one-to-many presentation or many-to-many conversation. Web conferencing is a way to facilitate communications among all the members of the group even if the group is spread out between a dozen or more locations.

10. What value do the social network hold for business? Social networks connect people at low cost; this can be beneficial for entrepreneurs and small businesses looking to expand their contact bases. These networks often act as a customer relationship management tool for companies selling products and services. Companies can also use social networks for advertising in the form of banners and text ads. Since businesses operate globally, social networks can make it easier to keep in touch with contacts around the world

11. What value do the social network hold for community group? Social network groups are especially useful for community groups. We get enough functionality to keep everyone in touch with each other, at no cost to anyone involved. No IT support is necessary, nor do we have to lease web hosting space; the social network site maintains all the servers and technology. And, of course, all of these sites are easy to join and easy to use.

12. What value do the social networks hold for family? Social network makes the family easily re-connect and strengthen family bonds. No matter what computer experience one have, it’ll easily help the family build and secure it's history and memories. We can share important dates and events on the family calendar. Post photo galleries in minutes. Upload streaming videos of family to share online with relatives in complete privacy.

19. What is a blog in terms of organization?A blog is a collection of individual posts or messages. The posts are arranged in reverse chronological order, with the new post at the top which makes it easy to keep track of the latest developments. The older posts are relegated to the blog archives which are generally accessible via a link in the sidebar column and at the end of each post we can find a link to comments where the blog readers can register their own personal comments about any given post.

20. How do you collaborate via blogs?A blog need not be the work of a single author it can include posts from multiple contributors as well

as comments on each of those posts. This makes a blog useful for keeping track of group project. We can create a blog and host it in the web or the company's server and assign membership to your team members so that they can initiate new posts and comment on other's posts.

21. List out some of the blog hosting communities.www.Blogger.comwww.TypePad.comwww.WordPress.com

22. What is wiki?Wiki is a collection of web pages where any users can contribute or modify content.

Wikis enables all users not only to write new articles, but also to comment on and edit existing articles

23. What is the use of wikis?1. Anyone can edit.2. Easy to use and learn.3. Wikis are instantaneous so there is no need to wait for a publisher to create new edition.4) No need to install HTML authoring Tools.5) Minimal Training may be needed.6) Wikis can work wonders as project management tools

UNIT V

1. What is cloud storage?Cloud storage involves exactly storing the data with a cloud service provider rather than on a local

system. The data stored on the cloud, hosted on third party servers, can be accessed via an Internet link. Hosting companies operate large data centres, 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 can themselves use to store files or data objects.
