FROM PHYSICAL TO VIRTUAL

≈ over 9000

History of virtualization

• MIT’s Project MAC

– Batch processing

– Time sharing

– Multiple Access Computer July 1, 1963

History of virtualization

Virtual Machines.

– CP-40/CP-67

• User interaction

• Virtual Machines

– CP/CMS

• Control Program

• Console Monitor System

IBM mainframe -System/360

History of virtualization

Another way.

• A multi-user computer:

– MultiCS

– Multi-user operating systems

History of virtualization

Software PC emulator

SoftPC from Insignia Solutions.

• 1987 - 1st of a kind:– DOS apps on Unix

• 1989 – keep growing:– DOS \ Win apps on Mac

• 1997 – competitors…

SoftPC in 1992

History of virtualization

Followers of SoftPC:

• Apple Virtual PC

• VMWare workstation

• Citrix - Xen

• Microsoft Virtual PC

Vmware Workstation running on MS Windows XPemulate MS Windows NT.

Current state

• Hypervisor - a piece of computer software, firmware or

hardware that creates and runs virtual machines.

Type 1

• Vmware ESXi • MS Virtual PC• Vmware WorkStation• Virtual Box

• MS Hyper-V• Citrix XenServer

Type 2 Type 0

Current state

VM - is a software implementation of a machine (i.e. computer)

that executes programs like a physical machine.

Who is who

• VMware ESXi

• Microsoft Hyper-V

• XenServer

Who is who

VMware ESXi

• Hypervisor type 1

• VM as a bunch of files

– .vmx

– .vmdk

• VM as a process

Who is who

VMware VM Snapshot

Who is who

VMware vCenter:

- Mangement

- vMotion

- HA

- FT

Who is who

VMware ESXi

• Pros

– ease of management

– user/admin friendly

– Scalability

– Stability

– long history

• Cons

– Costs

– Obsolete limitations

Who is who

Simple, isn’t it?

Who is who

Who is who

Who is who

• Microsoft Hyper-V

• Pros

– low prices

– most Enterprise level features are free

– support modern requirements for hardware

• Cons

– part of hypervisor - Windows OS

– CSV

– some daily basics require lot's of PowerShellscripting

Who is who

Where is Xen?

Disasters and recovery

Possible issues and threats

– Hardware issues

– hypervisor issues

– management issues

– Guest OS issue

Disasters and recovery

Pixar studio stories - The movie vanishes

Disasters and recovery

What to do – benefits being virtual.

VM is a bunch of files. We can:

• copy VM files and use them to recreate VM

• collect changes and save them

• Copy only useful files (ex. user data)

Disasters and recovery

VM Backup requirements:• Do not affect production• Fast• Reliable• Easy to restore

One of backup solutions has an ability to help us…

Bad backup

Disasters and recoveryBackup types:

Disasters and recoveryBackup workflow

Disasters and recoveryRestore from backup

– File level restore:

recover an individual file from Guest file system

– VM restore:

restore VM files and register them as VM

Disasters and recovery

Restore from backup

– Instant RecoveryWhy should we restore VM if we can start it directly from backup?

What to next?

Use cases:

– Data analisys

– Hardware independent

– High available apps

– Gaming apps

– Web and Mobile apps

Today’s implementations:• Vmware vCloud Director• Commercial clouds:Google, Amazon, HP
