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
Clouds
