  • 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.
