The hypervisor loads the virtual machine images to create multiple virtual operating systems. Usually done as software although embedded . Each virtual machine has its own operating system and hardware resources such as a CPU, a graphics accelerator, and storage. . what is the underlying hypervisor for ec2 This is true regardless of the underlying hypervisor, and unless the configuration has been fully configured from the ground up with separation of I/O as a design consideration, at one or multiple points there's likely not going to be separation of the I/O workloads. IT administrators can configure, deploy, and manage software applications without being constrained to a specific hardware setup. They allow you to scale computing services efficiently on limited hardware infrastructure. Persistent storage can be provided by Amazon EBS (Elastic Block Storage). The "hypervisor's" field of the describe_instances response will continue to report Xen for all EC2 instances even though they're running under the new hypervisors. A hypervisor abstracts the hardware from the software environment. Many people know that Amazon Web Services are one of the big players in the cloud computing business, and especially their Infrastructure as a Service offering EC2 is becoming increasingly popular.
