Virtual Machine components

• Image for a virtual machine is essential for hard disk contents
• CPU and RAM are provided from the size selected
• Disk size and type can be selected during vm creation
• VM will get a network interface and an option to select public ip if required
  
• Credentials:
  • Linux:
    • Username and Password
    • Username and key
  • Windows:
    • username and Password

EC2 instance (Virtual Machine) creation in AWS

• In AWS by default there is a network available.
• For screenshots refer classroom
• AWS supports only key based authentication by default.
• AWS Free tier for ec2
  • 750 hours of t2.micro or t3.micro

Linux VM

• Create the ec2 instance as discussed in the class
  
• SSH Command
  • password based authentication: ssh username@ipaddress
  • key based authentication ssh -i <path to pem> username@ipaddress
    
    
• To delete the instance
  

Windows VM

• Windows instances use remote desktop connections
• AWS allows us to generate password based on pem file
• Command to connect to windows mstsc -v <ip address>

Azure VM Creation

• In Azure by default there is a no network.
• For screenshots refer classroom
• Azure supports both password and key based authentication.
• Azure allows to set username while creation
• Azure Free tier for VM
  
• Azure resource have to be part of a resource group. This helps in managing multiple resources.
• For creational steps refer classroom video
• Windows VM Quick Start
• Linux VM Quick Start
  
  
  
• Exercise: Create a free tier windows vm in Azure
