What is a Virtual Machine
- A virtual Machine is created on the Physical machine by using a software which is called as Hypervisor.
- While creating a VM from a physical server (Host) we need to assign
- CPU & RAM to the virtual machine
- Storage space which will act as virtual hard disk to the VM
- VM can be started, stopped or removed. While VM is running it consumes
- CPU & RAM
- Storage Space
- When the VM is stopped it consumes only storage space.

- AWS also gives us a way to create VMs which is called as EC2.
- While creating a VM it is referred as EC2 instance.
- To select
- CPU and RAM, AWS gives instance size
- Virtual Disk, AWS gives EBS
- While EC2 instance is running, AWS will charge for instance type and EBS and when the EC2 instance is stopped, we will be charged only for EBS
