    Study Notes

    Virtual Layer

    • Virtualization is the logical abstraction of physical computing resources including compute, network and storage resources
    • Enables a resource to appear larger or smaller than it actually is
    • It enables a multitenant environment to improve the utilization of physical resources
    • Benefits include optimized utilization, reduced cost and complexity, faster deployment and more flexibility
    • The virtual layer enables the resource pooling and rapid elasticity characteristics of cloud infrastructure
    • The virtual layer contains virtualization software, resource pools, and virtual resources

    Virtualization Process and Operations

    • Virtualization software deployed on:
      • Compute systems
      • Network devices
      • Storage devices
    • Create resource pools from:
      • Processing power and memory
      • Network bandwidth
      • Storage
    • Create virtual resources such as
      • Virtual machines
      • Virtual networks
      • LUNs (Logical Unit Number)

    Compute Virtualization Software

    • A hypervisor is software installed on a compute system to enable multiple operating systems (OS) to run concurrently
    • The hypervisor kernel acts like an OS kernel designed to run multiple VMs concurrently
    • Each VM is assigned a Virtual Machine Manager (VMM) which abstracts hardware

    Types of Hypervisors

    • Bare-metal hypervisor:
      • Installed on bare-metal hardware, an OS
      • Requires certified hardware
      • Suitable for enterprise data centers and cloud infrastructure
    • Hosted Hypervisor:
      • An application installed on an OS
      • Relies on the OS, running on physical machines for device support
      • Suitable for development, testing, and training purpose
