Comprehensive Study on Linux Server Administration Practices

The document covers a practical assignment on Linux Server Administration which involves three main sections: comparison of three cloud service providers based on various features; creation and configuration of a virtual server instance using an IaaS provider, specifically focusing on an Ubuntu server setup; and installation and testing of a web server. The first section compares AWS, Azure, and Google Compute Engine across service features, IPv4/IPv6 support, and security. The second demonstrates setting up an Ubuntu-based virtual machine with NGINX web server installation steps included. Lastly, it details configuring the server to allow HTTP traffic and verifying its operation through accessing a webpage via public IP. This assignment is supplemented by bibliographic references for further reading on cloud computing technologies.

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:
