    • The Fundamentals of Virtualization
      Virtualization 101
      What is it?
    • The Fundamentals of Virtualization
      Traditional Computing
    • The Fundamentals of Virtualization
      Computing in a Virtualized Environment
    • The Fundamentals of Virtualization
      Type 1 – Hypervisor (Bare Metal)
    • The Fundamentals of Virtualization
      Type 2 – Hypervisor (Hosted)
    • The Fundamentals of Virtualization
      Type 1 Hypervisors
      VMWareESXi
      Citrix XenServer
      Microsoft HyperV
    • The Fundamentals of Virtualization
      Type 2 Hypervisors
      VMWare Workstation/Player/Fusion
      VirtualBox
      Parallels
      Microsoft Virtual PC
    • The Fundamentals of Virtualization
      Features of Virtualization
    • The Fundamentals of Virtualization
      Transparent sharing of resources
      Memory, CPU, Network, Disk
      Hardware is decoupledfrom operating system
      Underlying hardware becomesa pool of resources
    • The Fundamentals of Virtualization
      Live Migration
      Virtual servers can be moved between physical hardware while running
      Allows for maintenance on hardware without downtime
    • The Fundamentals of Virtualization
      Management
      Single point of management for all of your virtual machines
      Allows for building of custom templates for rapid deployment
      Snapshotting technologies allow for block level rollbacks in event of failure
    • The Fundamentals of Virtualization
      High Availability
      Virtual Servers can be set to boot on alternate server in event of hardware failure
      Two instances of same virtual server can be running on multiple hosts
    • The Fundamentals of Virtualization
      Why Virtualize?
    • The Fundamentals of Virtualization
      Server Sprawl
      On average, physical servers run between 5-20% utilization.
      The power, space, and cooling costs can’t justify the servers workload.
    • The Fundamentals of Virtualization
      How to mitigate Server Sprawl?
      Server Consolidation
      Host multiple operating systems and environments on single piece of hardware.
    • The Fundamentals of Virtualization
      Consolidation Ratios
      Consolidation ratios for physical to virtual machine migrations can range from 10:1 up to 30-40:1.
    • The Fundamentals of Virtualization
      Significant Cost Savings
      Power
      Cooling
      Space
      Hardware costs for new servers
      Operational efficiency
    • The Fundamentals of Virtualization
      Server Downtime
      Keep your organization running optimally leveraging the features of virtualization.
