3. Why use virtualization? It can save you $$$.
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

5. Who’s using server virtualization & when did you start using it?
#SPICECORPS

6. How much more efficient is your server room with virtualization?
How much $$$ have you saved?
#SPICECORPS

7. Let’s cover some basics…
#SPICECORPS

8. 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 that behaves like a physical machine capable of hosting an OS and apps
A hypervisor is software that creates and runs virtual machines

11. Let’s (virtually) dig deeper…

12. What’s a virtualization guest and host?
Virtualization “guest” Guests are VMs that you run on your virtualization platform of choice. Some admins call the host & guest the parent and child.
Virtualization “host” If you’re using a bare metal Virtualization platform like Hyper-V or ESXi, the host is the Hypervisor.
If you are using a Type-2 Hypervisor like VirtualBox, the host is the OS.

13. Guests Guests HostOS Host Machine
There are 2 main types of hypervisors, which allow for abstraction of physical hardware resources from the OS
Type 1 (bare metal or native)
hypervisor runs directly on hardware
without the need for an OS
Type 2 (hosted) hypervisor runs on
top of a conventional OS (the host)

14. Who are major virtualization players?
Type 1 (native) hypervisors
VMware ESXi
Microsoft Hyper-V 
Citrix XenServer
KVM
Oracle VM
Type 2 (hosted) hypervisors
Parallels
VMware Player, Fusion
Microsoft XP Mode
Oracle VirtualBox
#SPICECORPS

15. (What about Xen and KVM?)
What hypervisor do you use and why?
Why VMware? Why Hyper-V?

MIGRATED VM
Live Migration – moving a virtual machine between 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 & High Availability - switching to redundant or standby servers, VMs, hardware components, or networks upon failure or termination

18. Provisioning – preparing a server with everything it needs for operation like memory, storage, compute, and network resources & setting up / installing software, drivers, identity information, etc.
Thin Provisioning – “as needed” provisioning that can increase virtualization efficiency
Self-service provisioning - allowing users to create their own VMs using software such as vCloud Director or MS App Controller
Self Checkout
#SPICECORPS

19. Snapshot – file-based copies of the state, disk data, configuration of a VM at a specific point in time.
Chargeback / Showback – tracking how many IT resources different departments or customers consume
Orchestration - automated arrangement, coordination, and management of complex computer systems & workloads
Infrastructure as a service (IaaS) - service model that delivers computer infrastructure (usually in the form of VMs). Hybrid models can run workloads on premises or with a cloud provider OS
APP VM
