The hypervisors general role is to provision, spin up, and retire the virtual machines as needed. Solution 2: us-west-2a with six EC2 instances, us-west-2b with six EC2 instances, and us-west-2c with no EC2 instances. Every physical machine has a hypervisor running on it. The Role of Hypervisor Technology. For example, if production, marketing, and customer support teams run their workloads on individual physical servers, it can result in idle resources. Portions of the EC2 instance memory are reserved and used by the virtual BIOS for video RAM, DMI, and ACPI. It replaces the host operating system, and the hypervisor schedules VM services directly to the hardware. Hypervisors are the underlying technology behind virtualization or the decoupling of hardware from software. As for a definition, a vCPU represents a portion or share of the underlying, physical CPU that is assigned to a particular virtual machine (VM). Each virtual machine is capable of executing its own programs. With the simple web service interface of Amazon EC2, you can obtain and configure capacity with little effort. The Amazon EC2 host system emulates some or all of the underlying hardware that is presented to the guest.
