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 Application
Google 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?

 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.

 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.

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.

 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.

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!

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 conferencing
E-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

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. 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 don’t need to use the same computer to access data nor do they have to carry around
physical storage devices.
 Cloud is secure form accidential erasure or hardware crashes because it is duplicated across multiple
physical machines.
 Virtual resources in the cloud are typically cheaper than dedicated physical resources.
 Cloud storage providers balance server loads and move data among various datacenters, ensuring that
information is stored close—and thereby available quickly—to where it is used.
3. What are the risks of storing data in the cloud?
 Large enterprises might have difficulty with vendors like Google or Amazon, because they are forced
to rewrite solutions for their applications and there is a lack of portability.
 The biggest deal-breakers when it comes to cloud storage seem to be price and reliability.
 This is where you have to get your vendor to ensure you’re getting a good deal with quality service.
4. What are the features of online file storage and sharing services?
 Sync Folders, Schedule Offsite Backups
 View / Edit Documents and Pictures Online
 Photo Slideshows, Video and Audio Streaming
 Secure
Online storage services employ robust security measures such as SSL encryption when files are
transferred, password-protected accounts and multi-level security.
 Offer Ample Storage Space at reasonable price
 Ease of Use
 Help&Support
Troubleshooting and technical resources are available, including tutorials, FAQs, user manuals and
community forums.
 Easy accessibility that helps to view and share files from anywhere, anytime.
