Setting Up and Testing a Web Server

This assignment focuses on setting up and testing a basic web server using Nginx on a cloud platform. It involves updating package sources, installing Nginx, configuring network security groups to allow web traffic on port 80, and finally verifying the web server's functionality by accessing its default webpage using the server's public IP address.

1. Comparing three Cloud Service Providers
In this section, three cloud service providers that is Amazon Web Services (AWS),
Microsoft Azure and Google Compute Engine is compared based on the different criteria such as
Service features, IPv4 and IPv6 addressing along with Redundancy and Backup.

2. Account with an IaaS virtual server hosting provider
2.1 Creating a virtual server instance
Step 1: Creating a new virtual machine

5LINUX SERVER ADMINISTRATION
Step 2: Search for version of Linux (Ubuntu)
Step 3: Select the version of Ubuntu Server (Ubuntu Server 16.04 LTS has been chosen)

6LINUX SERVER ADMINISTRATION
Step 4: Creating the instance of Linux server
Step 5: Choosing the appropriate size and features for the server (DS1 Standard has been chosen

7LINUX SERVER ADMINISTRATION
Step 6: Directed to server instance for configuration
2.2 Configuring the virtual server
Step 1: Configuring Availability set

8LINUX SERVER ADMINISTRATION
Step 2: Deployment of Server
Step 3: Purchase and Deployment of server

9LINUX SERVER ADMINISTRATION
Step 4: Deployment of Ubuntu Server in progress
Step 5: Installed instance of the Linux Server

10LINUX SERVER ADMINISTRATION
2.3 Testing the server using SSH and checking of processes
Step 1: Connecting to the server using SSH
Step 2: Logging into the server using SSH
Connect using ssh kiran-vm@13.75.142.37
Now enter password as kiran-VM 2017
Now connection has been established with the server as below:

11LINUX SERVER ADMINISTRATION
Step 3: Checking of processes running on the server

12LINUX SERVER ADMINISTRATION
List of all processes running on the server
3. Configure and test a Web server
3.1 Installing and configuring a web server
Step 1: Connect to server using SSH

13LINUX SERVER ADMINISTRATION
Step 2: After connection to the server using SSH  Update package source with the command
as below:
sudo apt-get -y update
Step 3: Now install NGINX package with the following command:
sudo apt-get -y install nginx

14LINUX SERVER ADMINISTRATION
Step 4: Now exit the SSH session and open port 80 for web traffic
Click the name of resource group
Now select network security group

15LINUX SERVER ADMINISTRATION
Clicking the network security group opens the configuration window as below:
Now click on Inbound Security rules on the left hand menu

16LINUX SERVER ADMINISTRATION
Next click on Add and set the configuration as below:
Now after clicking ok a message will be that security rule created successfully as shown below:

17LINUX SERVER ADMINISTRATION
Now default webpage can be seen by accessing the Public IP address of the server as below:
3.2 Testing the operation of web server
The IP address for the server is 13.75.142.37
