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)
