Cloud Computing Assignment 2: Azure VM Creation, SSH & Key Generation

This document presents a comprehensive solution to a cloud computing assignment focused on creating a virtual machine (VM) in the Azure portal. The assignment involves generating SSH keys using PuttyGen, creating a resource group with a specific naming convention, and deploying an Ubuntu Server 18.04 LTS VM. The solution details the process of key generation (RSA, 2048 bit), saving private and public keys, and creating the resource group in Azure. It addresses troubleshooting encountered during resource group creation and VM deployment. Furthermore, the solution covers the steps involved in connecting to the VM via SSH using PuTTY, including loading the private key for authentication and logging into the Ubuntu environment. The document also describes different VM power states and obtaining the private and public IP addresses of the created VM. Finally, the solution demonstrates logging into the Linux VM using Putty with the private key and passphrase for secure access.

CLOUD COMPUTING

Key Generation using Putty_Gen
Visited https://www.ssh.com/ssh/putty/download
Downloaded putty and installed it in my windows desktop.
Now my putty folder got puttygen.exe, psftp.exe, pagent.exe. putty.exe, pscp.exe,
1

Installed Putty_Gen in my windows system.
SSH-2 RSA with 2048 bit key size is selected and created public and private key pair
2

Saved the private key as myprikey.ppk and the pass phase for my private key file is
“PPKPASS”
Saved the public key as mypubkey.txt
The files are attached here.
Resource Group Creation in Azure
3

Faced some problems in my credit card and hence used my relative’s credit card with his user
name “arumugam”. Resource group is created in my First Name “Aravind” and my student ID
“41534”.
Opened Azure
Found Example/Link in the top right corner
Opened https://shell.azure.com
4

Got Cloud Shell
Created resource group

6

Created another resource group using "az group create" command
az group create --name Aravind1_41534 --location eastus

Ubuntu 18.04 LTS VM Creation
For creation of VMs, VM Images are needed.
Used "AZ VM image list" command to see all the available images.

9

az vm image list --output table
10

Got the following table that shows the vm images.
Got the full list by adding -all argument
az vm image list -all --output table
Here Ubuntu 18.04 LTS vm image is needed.
So I used the filter to see the availble ubuntu images.
az vm image list --offer ubuntu -all --output table
I noted down & copied the following URN column
