Abstract
Computers have turned into a vital piece of life. We require computers
everywhere, be it for work, research or in any such field. As the utilization of
computers in our everyday life expands, the computing resources that we need
also go up. For companies like Google and Microsoft,`

Cloud computing is a paradigm shift in which computing is moved away from

personal computers and even the individual enterprise application server to a
‘cloud’ of computers. Which can give the distinctive registering assets of their
customers? Clients of this framework require just be worried about the computing
resources administration being requested. The fundamental points of interest of
how it is accomplished are avoided the client. The data and the services provided
reside in massively scalable data centers and can be ubiquitously accessed from
any connected device all over the world. Google, Microsoft, and Amazon, Alibaba
Rackspace has started providing cloud computing services. Amazon is the pioneer
in this field.

CHAPTER 1: INTRODUCTION
1. Introduction
Cloud computing is a growing technology which could change traditional IT systems. Cloud computing
makes it feasible for an organization IT to be more flexible, save costs and process information and data
faster than with traditional IT. The problem though lies in the riskiness of this new technology.

Cloud computing has recently emerged as a new paradigm for hosting and delivering services over the
Internet Cloud computing is attractive to business owners as it eliminates the requirement for users to plan
ahead for provisioning, and allows enterprises to start from the small and increase resources only when
there is a rise in service demand. However, despite the fact that cloud computing offers huge opportunities
to the IT industry, the development of cloud computing technology is currently in its infancy, with many
issues still to be addressed.

Cloud computing has gained a lot of publicity in the current world of IT. Cloud computing is said to be the
next big thing in the computer world after the internet. Cloud computing is the use of the Internet for the
tasks performed on the computer and it is visualized as the next generation architecture of IT [1].

2. Motivation
I was highly motivated science I got my fist class on cloud computing at BITM. Course coordinator was an
expert cloud professional. He gave us a good overview and told us the future of cloud computing. The most
important things are:

Scalability – Cloud computing is highly scalable. Use scalability we can scale up and down our cloud
resources. A cloud-based IT infrastructure is more versatile – notably in terms of scalability – that is local,
intranet-based infrastructure.

Reliability – Cloud computing service providers provide stable and reliable resources. They provide up to
99.99 % uptime. They make multiple copies of our resources and our data and spread them multiple regions.

Virtualization – Because cloud-based IT infrastructure can be virtualized and geographically dislocated,

startups are freed from having to consider the physical location of its IT infrastructure and data centers in
business operations decisions.

Affordability – Under traditional infrastructures, startups may not receive – or have the financial
wherewithal to purchase – certain features that are often offered to cloud computing customers at
substantial discounts. How do these benefits pass on to startups and other small companies? Because the
marginal cost to the cloud computing provider of many features (such as enhanced security) may be very
low (or even negligible), otherwise unaffordable services may be offered for free to startups using cloud
computing options.

3.3.2 Elastic Compute Cloud (EC2)

Overview

EC2 stands for Elastic Compute Cloud. EC2 is a virtual machine. Where we can create and develop our own
web server/web applications. We can create our instance by choosing specific Availability Zone [4]. Figure
3.3.2 showing how ec2 works.

Figure 3.3.2.: How EC2 works

Launch an Instance

Step1: At first, we have to go to https://console.AWS.amazon.com/ec2/. Here we will see EC2 dashboard

with details about EC2.
Step2: Select Launce Instance. Process shown at figure 3.3.2

 lOMoARcPSD|22583867

Figure 3.3.2: Select Amazon Machine Image (AMI)

Step 4: After that, we have to select Instance Type. I am using AWS free account that’s why I have some
limitation. I choose t2.micro instance which consists 1 vCPU, 1 GB Memory(EBS Elastic Block Storage) and 1
network card. Then select Configure instance.
Step 5: Now we will set a number of instances we need, set Virtual Private Cloud(VPC), subnet. Public IP,
IAM role. Then select add storage.
Step 6: Here we set how many root volume we need. Here we will set 8 GB of General Purpose Storage.
Then select Add Tag.
Step 7: In this section, we will add tag name “DaffodilEC2_1”. Then select Security Group.
Step 8: Here we have to create a security group for our EC2 machine named “DaffodilSG”. We will add HTTP
and https rules and which rules we want for our instance. Then click a Review and Launch. After checking
all is ok we launch the instance then AWS tell us to create a private key, AWS will save the public key. When
we will log into our instance this key will be needed? Otherwise, we won’t able to log in. So this key very
Important. After that, we will Launch the Instance. Now we can see our instance in the Instance section. By
selecting an instance we can the details overview of that instance, process shown at figure
3.3.2.
After that, we have to log in our instance through Putty. We need to fill out Public IP, username and our
Private key that we saved while we were launching our instance.

RDS stands for Relational Database Service. RDS is a SQL database service that provides a wide range of
SQL database options to select form.

SQL options include:

• Amazon Aurora
• MySQL
• MariaDB
• PostgreSQL
• Oracle
• Microsoft SQLServer
There are two main types of databases in the world:

• Relational Databases known as SQL

• Non-Relational Databases known as NoSQL

Figure 3.3.4: How RDS works

In this section, we will see how to create an RDS database and access that database through our EC2. Figure
3.3.4 showing everthing. At first, we will create a SQL RDS database then connect.

 lOMoARcPSD|22583867

Create RDS

Step 1: At first, we need to go to https://console.AWS.amazon.com/rds/. Then we have to create a subnet

group “Daffodilsubgrooup” for our database. In this section, we will set DB Subnet Group name, Description,
VPC ID, Available Zone, Subnet ID. Then create, figure 3.3.4 showing processes .

Figure 3.3.4: Create DB Subnet Group

Step 2: Now we have to go back to our RDS Dashboard instance. Then Launched DB instance. A new section
will appear in front of us. Then we can choose either Amazon Aurora or MySQL or MariaDB or PostSQL or
Oracle database. After that, we have to select Dev/Test MySQL. Now we have to set some configuration
such as DB name “MySQL”, version, DB Instance Class “t2.micro”, storage type, storage size, DB instance

3.3.5 Virtual Private Cloud (VPC)

VPC stands for Virtual Private Cloud. Where we can create our own virtual network. We can create more than one VPC at a time. In this
VPC we can set up web application or database. Amazon AWS has twelve regions and every region has more than three availability
zone. VPC is a private sub-section of AWS that we control, in which we can place AWS resources, for example, EC2 instance or database,
in figure 3.3.5 we see our VPC with resources. We have full control over who has access to the AWS resources that we place inside
our VPC [7].

Figure 3.3.5: Virtual Private Cloud

In VPC Section We Have

• Internet Gateway
• Route Table
• Network Access Control List (NACL)
• Subnet
• Availability Zone

Internet Gateway
IGW or Internet Gateway is a combination of hardware and software provides our private network with a route to the
world (meaning the Internet) of the VPC.
To create an IGW steps are:
Step 1: Go to VPC section select Internet Gateway.
Step 2: Create Internet Gateway
Step 3. A pop-up window will appear. Add tag name “DaffodilIGW”.
Note:

Downloaded by Pralin Khaira (pralin.khaira.1903@gmail.com)

 lOMoARcPSD|22583867

1. Only 1 IGw can be attached to a VPC at a time.

2.An IGW cannot be detached from a VPC while there are active AWS resources in the VPC. Route
Table

The route table is set of rules named routes. Where admin determine where network traffic is to go. Ever VPC needs a
route table. Without a route table network traffic won’t work properly.

To create a Route table:

Step 1: Go to VPC section select Route Tables.

Step 2: Create Route Table
Step 3: A pop-up window will appear. Set a tag name” DaffodilRT”
Step 4: Select a VPC, in which our route table will work. At late yes create
Note:
1.Unlike an IGW, we can have multiple active route tables in a VPC.
2.we cannot delete a route table if it has dependencies. Network
Access Control List (NACL)

In a simple sentence, NACL is a security layer for our VPC, which works like a firewall for control data/packets in or out
through our VPC. We can set inbound and outbound rules in NACL. Rules applied based on rule # from lowest to highest
[7].

To create an NACL:
Step 1: Go to VPC section select Network ACLs.
Step 2: Create Network ACL.
Step 3: A pop-up window will appear. Set a tag name” DaffodilNACL”.
Step 4: Select a VPC, in which our NACL will work. At late yes create.
Note:
1. Rules are evaluated from lowest to highest based on rule #.
2. Any new NACL we create DENY all traffic by default.
3. A subnet can only be associated with one NACL at a time.

Subnet

A subnet, shorthand for subnetwork, is a sub-section of a network. Generally, a subnet includes all the computers in a
specific location. Circling back to the home network analogy we used in the VPC Basic lesson- if we think about our ISP
begin a network, then our home network can be considered a Subnet of our ISP’s network. [7]

To create a Subnet:
Step 1: Go to VPC section select Subnets.
Step 2: Create Subnet.
Step 3: A pop-up window will appear. Set a tag name”Public Subnet 1/Private Subnet 1”.
Step 4: Select a VPC, in which our Subnetwork.
Step 5: Select Availability Zone.
Step 6: set an IPv4 CIDR block “172.16.1.0/20”. Al last yes create.
Note:
1. Subnets must be associated with a route table.
2. A public subnet has a route to the internet.
At Last, We need to connect all thing using configuration tab. Every section has own configuration tab. Just select and
set as we needed.

6. Identity and Access Management (IAM)

Identity and Access Management is the most important part of our security. We can deploy our own security policies in
here. We can create and control our users.
We have several things to do in IAM section such as:
• Multifactor Authentication or 2MFA
• Create Users & Policies
• Setup Group & Policies
• IAM Roles
Multifactor Authentication or 2MFA

MFA is an abbreviation for Multifactor Authentication. It’s an extra layer of security. That’s how we can protect our root
account get hacked. This service provided by a 3rd party company which can be free of paid service. It generates random
six-digit code every couple of second when we want to log into our root account. It works via smartphone or tablet or
used the app: Google authenticator, process shown at figure 3.3.6,

Figure 3.3.6: How Multifactor Authentication or 2MFA works

Setup a Multifactor Authentication

Step 1: Go to IAM section and select Activate MFA on your root account.
Step 2: Select Manage MFA. After that select the type of MFA device to activate. I choose A virtual MFA device. Select
next.
Step 3: New pop-up window will appear. It says If you want to active this feature you have to install an application on
your smartphone or PC or another device. Select next step
Step 4: Now will see a QR code. We need to scan this QR code by our Smartphone authentication. This time I am using
Google authenticator. After that, we will give that six-digit code into authentication code box. Select Active Virtual MFA.
A successful message will appear. All done. Select finish, process shown at figure 3.3.6.

Create Users & Policies

In this section, We will create some user and set permission or policies for those users. Let’s begin:

Step 1: Go to IAM select Users. Select add users top left corner.
Step 2. Set a username. check AWS Management Console Access, check the custom password. Give a password for our
user. Select next
Step 3: In this section, you can add this user in a group. And we are going to attach some policies by selecting attach
existing policies directly. Now policies are shown, I select some policies for example AmazonEC2FullAccess,
Amazons3FullAccess. You can add more or less as your wish. Select next.
Step 4: Here we will see all we have done some time ago just review that everything is ok. And select Create user. Step
5: Now you have to download a CSV file for that user. Where you can find a link to login to AWS. Close the window.

IAM Roles

In this section, we are going to attach two AWS service. Where one AWS service can access another service when needed.
Step 1: Go to IAM select Role. Select create new role top left corner.
Step 2: Set a group name ”EC2”. select next.
Step 3: select an AWS service which is going to attach another service.
Step 4: Now select your desired service I choose AmazonS3FullAccess. Select next
Step 5: just review and create a role. New role created. How role works shown at
figure 3.3.6 below.

Figure 3.3.6: How Role works

3.3.7 Simple Notification Service (Amazon SNS)

SNS is an AWS service that allows us to automate the sending of email or text message notifications, bases on events
that happen in your AWS account. Using SNS service we can track our web application and send push notification
through SNS to our email address, process shown at figure 3.3.7 [8].

Create an SNS

Step 1: At first we have to go to Simple Notification Service. Select create topic. Now we are going to create a topic
named “Auto scaling”.
Step 2: Now give a topic name “Auto scaling”. And a display name “Auto scale”. Create topic.
Step 3: Now we need to create a subscription. New pop up appear. Change protocol to Email and give a valid email
address into endpoint section. Then create a subscription.
Step 4: It’s time to verify the submitted email. AWS sent a mail to our mail address. Just click the link Confirm
Subscription. Go back to the SNS and see a subscriber number.

3.3.9 Elastic Load Balancing

Elastic Load Balancer evenly distributes web traffic between EC2 instances that are associated with it. ELB equally
distribute incoming web traffic to multiple EC2 instances which are located in multiple Availability Zones. Fault tolerance
is one of the most vital features of Elastic Load Balancer. When one Ec2 will crash or down then ELB pass web traffic to
another EC2 instance, process shown at figure 3.3.9. That’s how our WEB server or application won’t be offline never
[10].

Auto Scaling

Auto Scaling automates the process of adding or removing EC2 instances based on traffic demand for our application.
Auto scaling is one of the best-awarded Innovation of Amazon AWS. Using this service, we can deploy a minimum

 lOMoARcPSD|22583867

number of the instance at a time because of our system never goes down. Also, we can deploy a maximum number of
the instance when we need those instances will be active shown at figure 3.3.10 below [11].

Figure 3.3.10: How auto-scaling works

Create Auto Scaling

Step 1: At first, we have to go to EC2> Launch Configuration.

Step 2: Select an AMI” Ubuntu 16.04”.
Step 3: Select an Instance Type “t2. micro”.
Step 4: Create Launce Configuration. set a name “auto scaling”. Set a public IP for our instance, process shown at figure
3.3.10 below.

Figure 3.3.10: Launce Configuration of auto scaling

Step 5: Select storage type and add storage if needed.

Step 6: Configure Security Group. I make new one and named “DaffodilSG”, VPC, Subnet, process shown at figure 3.3.10
bellow.

Figure 3.3.10: Create Auto Scaling Group

Step 7: Review your configuration and create.

Step 8: Now we have to create Auto Scaling Group. Give a Group name “DaffodilASG”. Set group size. I set 2. After that,
you have to select a VPC for auto scaling group. Also, need to add subnets. IN advanced option we have to set
“DaffodilELB” into Classis Load Balancer field. And check ELB in health check section. Next
Step 9: Here we have to set minimum and maximum instance we want for auto scaling. After that click adds a new alarm
in Increase Group Size section and set some metrics. Do the same thing for Decrease Group Size. I set some metric
that’s why when EC2 CPU utilization goes over 70% it will create one more instance automatically. And when CPU
utilization goes below 30% one instance will be terminated automatically, process shown at figure 3.3.10 below.

3.4 Challenges
I faced many problems while working in cloud and making this report. I am using AWS free account, so there are many
limitations to using their services. I can only use some basic services to develop a highly available, cost effective, fault
tolerance scalable system. I also used the lucid chart to create UML Diagram and it is also a free account where is some
limitation. I can create only 60 objects using a free account. I made my project angle of Service Providers because of my
company only give those types of services. I made this system for the project only but it was not build based on any
person or organization requested requirements.

CHAPTER 5: CONCLUSION AND FUTURE CAREER

5.1 Discussion and Conclusion
Cloud computing is a newly developing paradigm of distributed computing. Virtualization in combination with utility
computing model can make a difference in the IT industry and as well as in social perspective. Though cloud computing
is still in its infancy but it’s clearly gaining momentum. Organizations like Google, Yahoo, and Amazon are already
providing cloud services. The products like Google App-Engine, Amazon EC2, and Windows Azure are capturing the
market with their ease of use, availability aspects, and utility computing model. Users don’t have to be worried about
the hinges of distributed programming as they are taken care of by the cloud providers [15].
