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

What is Server Virtualization?Hypervisors are the enabling technology of virtualization & cloud.

They allow abstraction of physical

hardware resources from software

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)

Why? Benefits of VirtualizationSave 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

Who is using Server Virtualization?

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

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

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

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.

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
