Transcript of "All about virtualization spiceworks - slideshare"

  1. 1. All About Server Virtualization Virtually everything you need to know Peter Tsai, Spiceworks IT Content Guru @supertsai
  2. 2. Presented by Spiceworks http://spiceworks.com/webinars
  3. 3. All About Server Virtualization What is virtualization? Why go virtual? Who are the players? How do I get started? Where can I learn more? What are other types of virtualization?
  4. 4. With Special Guest Bill Kindle Network/Systems Administrator - Dayton, OH 10 years in IT
  5. 5. What is Server Virtualization? Virtualization allows you to run multiple operating systems on a single physical computer inside of virtual machines (VMs) A virtual machine is a software implementation of a computer running an operating system that behaves like a physical machine A hypervisor is software that creates and runs virtual machines      1 processor core 10 GB storage 4 GB memory 2 network adapters Windows 2008 R2 VM VM VM APP APP APP OS OS OS Virtualization Layer HERE BE HYPERVISORS YARR!! Hardware Layer
  6. 6. What is Server Virtualization? Hypervisors are the enabling Guests Guests technology of virtualization & cloud. They allow abstraction of physical hardware resources from software Type 1 (bare metal or native) hypervisor runs directly on hardware Host without the need for an OS Machine Type 2 (hosted) hypervisor runs on top of a conventional OS (the host) Host OS Hypervisor Chart Image Credit: Wikipedia Commons
  7. 7. Why? Benefits of Virtualization Save Money More fully utilize your hardware resources Increase server density Power and cooling advantages Quick provisioning / allocation of resources Application isolation Redundancy / Failover / Disaster Recovery Increased uptime Workload flexibility and the Cloud Run legacy apps
  8. 8. Who is using Server Virtualization?
  9. 9. What are Virtualization concepts? Provisioning – preparing a server with the necessary resources it needs for operation such as allocating memory, storage, compute, network resources & setting up / installing software, drivers, identity information, etc Thin Provisioning – “as needed” provisioning Self-service provisioning - allows users to create their own VMs through software such as (vCloud Director or MS App Controller) Self Checkout
  10. 10. What are Virtualization concepts? Live Migration – moving a virtual machine between different physical machines or hosts without disconnecting clients or the application Load Balancing – distributing workloads evenly across multiple hosts so that resources are utilized efficiently Failover - switching to a redundant or standby computer server, system, hardware component or network upon failure or abnormal termination VM VM APP APP OS OS 95% 70% load Virtualization Layer Hardware Layer VM FAILOVER VM MIGRATED VM APP APP OS 45% 70% load APP OS OS Virtualization Layer Hardware Layer
  11. 11. What are Virtualization concepts? Snapshot – file-based copies of the state, disk data, configuration of a virtual machine at a specific point in time. Chargeback – billing departments based on IT resources consumed Orchestration - automated arrangement, coordination, and management of complex computer systems – simplifies processes VM VM APP APP OS OS
  12. 12. Who are the major virtualization players? Type 1 (native) Hypervisors VMware ESXi Microsoft Hyper-V Citrix XenServer Red Hat Enterprise Virtualization Oracle VM Type 2 (hosted) Hypervisors Parallels VMware Workstation, Player, Fusion Microsoft XP Mode Oracle VirtualBox KVM
  13. 13. What are other kinds of Virtualization? Virtual Desktop Infrastructure (VDI) decouples the workstation / desktop from the physical machine. Storage virtualization hides physical storage from the user and presents them with logical volumes. Network virtualization allows multiple physical networks to be consolidated into a single logical network, or a single physical network can be segmented into separate logical networks.
  14. 14. How do I get started with Virtualization? Determine your virtualization needs ◦ What are your main criteria? Research the options available Evaluate software (free versions / trials) Consult your peers / network
