Virtual Infrastructure in AWS

  • In AWS we work on virtual machines & virtual storages.


  • Virtual Machines are created on Physical Servers. The Disk of the Virtual Machine can be attached from
    • Same Physical Server => Instance Store
    • Different Physical Server in the Same AZ => EBS
  • In AWS, for VM (EC2) the operating system disk (os disk/root disk) will always be EBS
  • User will get options of Instance Store only for additional disks (Only for some instance types)
