1. INTRODUCTION
“Dpilot is the delivery of computing resources over the internet instead of your
computer’s hard drive.”
Dpilot is a cloud based data sharing and storage platform. Here, we can store our data in
form of files and can be accessed through any computer using the cloud computing.
Distinct users has their distinct and unique portals which is accessed using login
credentials made by the users only. Dpilot is a combination of cloud computing and
MERN stack development.
1.1 PRE –REQUISITE KNOWLEDGE
1.1.1 CLOUD COMPUTING
As defined...
“An emerging computer paradigm where data and services reside in massively scalable
data centers in the cloud and can be accessed from any connected devices over the
internet.”
Cloud computing is Internet based development and use of computer technology. It
typically involves the delivery of dynamically scalable and often virtualized resources as
a service over the Internet. The term cloud is used as a symbol for the Internet. The basis
of cloud computing is to create a set of virtual servers on the available vast resource pool
and give it to the clients. Any web enabled device can be used to access the resources
through the virtual servers. Based on the computing needs of the client, the infrastructure
allotted to the client can be scaled up or down. One of the key concepts of cloud computing
is that as and when the amount of data increases, the cloud computing services can be used
to manage the load effectively and make the processing tasks easier. Typical cloud
computing services provide common business applications online that are accessed from
a web browser, while the software and data are stored on the server.

2
Types of Cloud Computing:-
In practice, cloud service providers (CSP’s) tend to offer services that can be grouped into
three categories: software as a service, platform as a service, and infrastructure as a
service.
Software as a Service (SaaS):-
1. Provides the same software to different customers via a network, usually the
Internet. It is managed by third party venders.
2. Accessible via any computer without any downloads.
3. Software as a service features a complete application offered as a service on
demand. The most widely known example of SaaS is salesforce.com.
Platform as a Service (PaaS):-
1. Offer an Internet-based platform to developers who want to create services and
application but don't want to build their own cloud. Hence, No need to buy
hardware and software. Servers, storage and networking managed by third party
venders.
2. Someone producing PaaS might produce a platform by integrating an OS,
application software, and even a development environment that is then provided
to a customer as a service. The customer interacts with the platform through the
API, and the platform does what is necessary to manage and scale itself to provide
a given level of service.
Infrastructure as a Service (IaaS):-
1. Allows applications to be run on a cloud supplier’s hardware by allows you to
install a virtual server on their IT infrastructure.
2. No need to purchase servers, or network equipment.
3. Servers, storage and networking managed by venders whereas applications and
updates are managed by users.
Infrastructure as a service delivers basic storage and computing capabilities as
standardized services over the network. Servers, storage systems, switches, routers, and
other systems are pooled and made available to users.

1.1.2 MERN FULL STACK DEVELOPMENT
MERN (MongoDB, Express, React, Node.js) is another popular full stack development. It
is usually considered as an alternative to MEAN stack development. Below is the
architecture of MERN:
I. MongoDB - Database layer
II. Express - Middleware for Nodejs
III. React- front end (User Interface)
IV. Node.js - web server logic
The main difference between MERN and MEAN stack is Angular and React. Both
Angular and React does the job for your requirement. Its personal choice which one to
use. Before learning MERN stack development, we should have knowledge of
HTML/CSS, JavaScript, React JS, Node JS.

2. FEASIBILITY STUDY
The most important step in any project is determining the viability of the idea. This is called
Feasibility Study. Feasibility study is used to assess the strengths and weaknesses of a
proposed project and present directions of activities which will improve a project and
achieve desired results. The nature and components of feasibility studies depend primarily
on the areas in which analysed projects are implemented. Feasibility literally means
whether some idea will work or not. It knows beforehand whether there exists a sizeable
market for the proposed product/service, what would be the investment requirements and
where to get the funding from, whether and wherefrom the necessary technical know-how
to convert the idea into a tangible product may be available, and so on. It is a process for
making sound decisions and setting direction. A feasibility study is designed to provide an
overview of the primary issues related to a business idea. The purpose is to identify any
"make or break" issues that would prevent your business from being successful in the
marketplace. In other words, a feasibility study determines whether the business idea makes
sense. A feasibility study looks at the following major areas:
i. Market Analysis.
ii. Technical Analysis.
iii. Financial Analysis.
iv. Economic Analysis.
v. Legal Analysis.
2.1 Market Analysis
A market is the arena for interaction among buyers and sellers. From seller’s point of view,
market analysis is primarily concerned with the aggregate demand of the proposed
product/service in future and the market share expected to be captured. Success of the
proposed project clearly hinges on the continuing support of the customers. The cloud
services market in India is forecast to grow at over a CAGR (Compound Annual Growth
Rate) of 22% during 2015-2020. Rising availability of cloud services at economical price
models and the ease of implementation are the major growth drivers for cloud services in
India. In addition, increased government spending on new e-governance projects based
on cloud technology is likely to drive the market for cloud computing services in India over
the coming years. Software-as-a-Service (SaaS) emerged as the leading market segment
holding majority market share in 2014 in India. Application hosting and E-mail remained
the leading services to utilize cloud technology extensively in India. Growing at over a

5
CAGR of 50%, private cloud dominated cloud computing ecosystem in India during 2010-
2014. Improved data security features and exclusive control remain the key factors
contributing to growth of private cloud in India. However, private cloud adoption is largely
restricted to large enterprises in present times. This is due to the fact that higher initial
investment discourages small and medium enterprises to opt for private cloud deployment.
According to the analysis, there is a very large scope for adaption of cloud computing in
India.
2.2 Technical Analysis
It is based on MERN Stack development, hence based on the latest technical platforms.
Backend is based on the Node.js and IDE used is WEBSTORM which is user-friendly
whereas frontend is based on the react on the same IDE. Both are the latest technologies,
Hence, anyone who knows the basics of these can easily amend the app if needed.
MongoDB is used for the data management which has its unique features – it does not
have pre-defined schemas i.e., we have dynamic schemas. It uses JSON (JAVA SCRIPT
OBJECT NOTATION). Also, it has unique object IDs which makes it more reliable and
easy for the data manipulation. It is also powered by a chat bot namely CabinCrew which
is made using MICROSOFT AZURE BOT SERVICE and MICROSOFT QNA MAKER
which makes sure that user does not get stuck in between and also helps user to make
the intermediate queries resolved in an effective manner.
2.3 Financial Analysis
The objective of financial analysis is to ascertain whether the proposed project will be
financially viable in the sense of being able to meet the burden of servicing debt and
whether the proposed project will satisfy the return expectations of those who provide the
capital. At present, we are offering Dpilot for free of cost with all the services but after a
limited period it will cost a minimal amount to its users. But, we are not expecting much
return as Dpilot available free of cost in the first year.
2.4 Economic Analysis
The emergence of cloud computing brings many benefits which are shifting the economics
of IT. Cloud technology standardises and pools IT resources and automates many of the
maintenance tasks performed manually today. Cloud architectures facilitate elastic
consumption, self-service, and pays-as-you-go pricing. Cloud also allows core IT
infrastructure to be brought into large data centres that take advantage of significant
economies of scale.

6
2.5 Legal Analysis
Cloud computing is a way to conduct business. Although, there is no country whose current
laws specifically deal with cloud computing, the legal climate in UK and Singapore appears
to be favourable for the purpose of its regulation. There is no general prohibition under
Swiss law to conduct business using cloud computing providers. As cloud computing
implies the outsourcing of certain tasks in different locations or jurisdictions, certain
limitations may be imposed or additional requirements may need to be satisfied. Such
limitations will depend on several factors.

4. SOFTWARE REQUIREMENT
SPECIFICATIONS (SRS)
4.1MERN STACK DEVELOPMENT:
4.1.1 MongoDB: MongoDB is a free and open-source cross-platform document-
oriented database program that provides persistence for your application data and is
designed with both scalability and developer agility in mind. MongoDB is written in C++.
Instead of storing data in rows and columns as one would with a relational database,
MongoDB stores JSON documents in collections with dynamic schemas. MongoDB's
document data model makes it easy to store and combine data of any structure, without
giving up sophisticated validation rules, flexible data access, and rich indexing
functionality. Our application will access MongoDB via the JavaScript/Node.js
driver which we install as a Node.js module.
4.1.2 ExpressJS: Express is the web application framework that runs your back-end
application (JavaScript) code. Express runs as a module within the Node.js environment. Express
can handle the routing of requests to the right parts of your application (or to different apps running
in the same environment). In this project, we have used Express to perform two functions:
A. Send the front-end application code to the remote browser when the user browses
to our app.
B. Provide a REST API that the front-end can access using HTTP network calls, in
order to access the database.
4.1.3 ReactJS: React JS is a JavaScript library developed by Facebook to build
interactive/reactive user interfaces. Like Angular, React breaks the front-end application
down into components. Each component can hold its own state and a parent can pass its
state down to its child components and those components can pass changes back to the
parent through the use of callback functions. Complex React applications usually require
the use of additional libraries for state management, routing, and interaction with an API.
4.1.4 NodeJS: Node.js is a JavaScript runtime environment that runs your back-end
application (via Express). Node.js is based on Google's V8 JavaScript engine which is used
in the Chrome browsers.Third party modules, including the MongoDB driver, can be
installed, using the npm tool. Node.js is an asynchronous, event-driven engine where the

9
application makes a request and then continues working on other useful tasks rather than
stalling while it waits for a response. On completion of the requested task, the application
is informed of the results via a callback. This enables large numbers of operations to be
performed in parallel which is essential when scaling applications.
4.2 PHP: PHP is an acronym for PHP: Hypertext Processor. PHP is a server side
scripting language that is embedded in HTML. It is used to manage dynamic content,
databases, session tracking, even build entire e-commerce sites. PHP is a widely-used, free,
and efficient alternative to competitors such as Microsoft's ASP.PHP can send and receive
cookies .PHP can add, delete and modify data in your database. PHP can be used to control
user-access. PHP can encrypt data.
4.3 Azure Bot Service: Azure Bot Service provides tools to build, test, deploy,
and manage intelligent bots all in one place. Through the modular and extensible
framework provided by the SDK, developers can leverage templates to create bots that
provide speech, language understanding, question and answer, and more. A bot is an app
that users interact with in a conversational way using text, graphics (cards), or speech. It
may be a simple question and answer dialog, or a sophisticated bot that allows people to
interact with services in an intelligent manner using pattern matching, state tracking and
artificial intelligence techniques well-integrated with existing business services.
4.3.1 Microsoft QNA Maker: QNA Maker enables you to power a question and
answer service from your semi-structured content like FAQ (Frequently Asked Questions)
documents or URLs and product manuals. An easy-to-use graphical user interface
enables you to create, manage, train and get your service up and running without any
developer experience.
1. A complete no-code experience to create a FAQ bot.
2. No more network throttling. Pay for hosting the service and not for the number
of transactions.
3. Scale as per your needs. Choose the appropriate SKUs of the individual
components that suit your scenario. See how to choose capacity for your QnA
Maker service.

10
4. Full data compliance. The data and runtime components are deployed in the user's
Azure subscription and within their compliance boundary.

11. TEST TECHNIQUES
10.1 Introducing Selenium:
Selenium is a robust set of tools that supports rapid
development of test automation for web-based applications.
Selenium provides a rich set of testing functions specifically
geared to the needs of testing of a web application.
Selenium operations are highly flexible, allowing many
options for locating UI elements and comparing expected
test results against actual application behavior.
10.1.1The Seven Basic Steps of Selenium Test:
There are seven basic steps in creating a Selenium test script, which apply to any test case
and any application under test (AUT).
1. Create a WebDriver instance.
2. Navigate to a Web page.
3. Locate an HTML element on the Web page.
4. Perform an action on an HTML element.
5. Anticipate the browser response to the action.
6. Run tests and record test results using a test framework.
7. Conclude the test.
10.1.2Selenium Architecture:
Selenium has a client-server architecture, and includes both client and server
components Selenium Client includes:
1. The WebDriver API, which you use to develop test scripts to interact with page
and application elements.
2. The RemoteWebDriver class, which communicates with a remote Selenium server
Selenium Server includes a server component, to receive requests from Selenium
and Client's RemoteWebDriver class.
3. The WebDriver API, to run tests against web browsers on a server machine.
Fig. 11: Selinuim Logo

18
4. Selenium Grid, implemented by Selenium Server in command-line options for
grid features, including a central hub and nodes for various environments and
desired browser capabilities.
10.2 Selenium IDE:
It is an integrated development environment for Selenium scripts. It is implemented as a
Chrome and Firefox extension, and allows you to record, edit, and debug tests.
Fig. 12: Snapshot of Selenium IDE
10.3 Selenium Server:
Selenium Server receives Selenese commands from test program, executes them, and
reports back the results of running those tests. When a test program opens the
browser Selenium Core is automatically injected into it allowing Selenium server to control
it. Selenium core is a JavaScript program that executes Selenese command using browser's
JavaScript execution engine.
10.4 Selenium-WebDriver:
The WebDriver was introduced in Selenium 2.0 version it provides a simpler programming
interface with well-designed object-oriented API. It directly calls to browser using
browser’s native support for automation and features they support depend on browser you
are using. If your browser and tests will all run on same machine and your tests only use
WebDriver API, then you do not need to run Selenium-Server.

19
10.5 Using the code
Step 1: Setup Selenium WebDriver in your machine
To setup the driver create a folder in your drive say C:WebDriver copy respective driver
EXE(s) to this folder. Now add this folder path to PATH environment variable in your
machine. This is required as WebDriver API will search for the respective EXE to open
web browser.
Step 2: Run the application by providing arguments
Now you have two option to run the application one is to run from Visual Studio go
to Project>Properties>Debug tab provide command line arguments as shown below or
you can go to command prompt, navigate to debug folder and provide the arguments. The
screen shot below shows command line arguments to search for Selenium keyword in
google on Firefox browser.

12. CONCLUSION
Cloud Computing has the potential to be a disruptive force by affecting the deployment
and use of technology. We, as a team, took an opportunity to use this technology for the
purpose of data sharing and storage. Dpilot, presently as a desktop application, is a Cloud-
Based AI powered secured file transfer and storage system which is built upon MERN stack
development to help the on-boarding data to have a safe journey. Dpilot is flexible and also
an user-friendly desktop app which is capable of transferring data in an efficient manner.
Though, having disadvantages like unsecure, requires constant internet connection etc,
Dpilot comes up with a greater use in this modern era. However, there are lot of research
and investment in the area by the Information technology giants like Microsoft, Google,
Cisco, IBM in this area and the day is not far when the cloud will widespread adopted and
all the security and privacy issues will be handled. Cloud computing is a better way to run
your business. Instead of running your apps yourself, they run on a shared data centre.
When you use any app that runs in the cloud, you just log in, customize it, and start using
it. That is the power of cloud computing. It is a new technology that helps to save money
but the information can be attacked by hackers to be used it improperly. We also conclude
that it is very easy to use and is adaptable and has benefits to customers of all sizes.

21
13. LIMITATIONS
We have really worked hard on making Dpilot more successful and reliable but somewhere
it still needs more improvement so that it can compete with other top applications and also,
can give users an experience that they never felt before. Some areas where it needs to have
more improvement:
1. It requires a constant internet connection.
2. It does not work properly with low-speed connections.
3. At present, it cannot be used on android and iOS.
4. Data on cloud is not likely to be secured as cloud provides less security and privacy.
5. Data stored on cloud can be lost.
6. Physical location of the cloud server where the data is stored cannot be known.
7. Files cannot be manipulated locally.

22
14. FUTURE SCOPE
A cloud allows users to access application, information, and data of all sorts on an online
level rather than by use of actual hardware or devices. A company offering reliable cloud
technology allows for computing to be done in a much more shared way, as a cloud
provides a service rather than a product. Users get and share their information in a way that
can allow them to access and give access to the whole world or any groups of people within
their cloud.
i. As of now, Dpilot is a website available. We will provide mobile application which
will support the platform like Android, IOS and Windows Mobile.
ii. Easier hybrid cloud strategies.
iii. Making it more secure and reliable.
iv. Productivity tools and proactive policies.
v. More focus on Internet of Things (IoT).
vi. Managing the time and making it speedier.
vii. Making working of Dpilot offline i.e., we can share data when there is no
connectivity of internet.
viii. Allowing the Dpilot to share the data using WIFI hotspot in the absence of internet.
ix. Range: Making its range wider when running offline.
x. The bot available (additional feature of Dpilot) is QNA bot. Making the bot more
user friendly.
xi. Adding the chat option for the users while sharing the data over the cloud.
xii. Allowing all the formats of the files to be shared over the cloud.
xiii. Time is a valuable thing, hence increasing the speed of data sharing between cloud
and the user.
xiv. Cloud computing is the future for the organizations. Hence, there is large scope for
amendments in the cloud computing and leading to the enhancement of its application.
