VIRTUALIZATION BRIEF HISTORY

Слайд 4

Virtualization Brief History
What is Virtualization?
Key concept: Virtualization is the creation of

a virtual (rather than actual) version of something, such as an operating system, a server, a storage device or network resources.

Слайд 5

Virtualization Brief History
The Beginning

Слайд 6

Virtualization Brief History

Слайд 7

Virtualization Brief History

Слайд 8

Virtualization Brief History
Virtualization was first implemented in the 60-ies of XX

century by IBM as a way to logically partition mainframe computers into separate virtual machines. These partitions allowed mainframes to “multitask”: run multiple applications and processes at the same time. Since mainframes were expensive resources at the time, they were designed for partitioning as a way to fully leverage the investment.
IBM M44\44X was the first computer system that used the “virtual machine” concept . It was based on IBM 7044 mainframe.

Слайд 9

Virtualization Brief History
In 1999, VMware introduced virtualization to x86 systems to

address many of these challenges and transform x86 systems into a general purpose, shared hardware infrastructure that offers full isolation, mobility and operating system choice for application environments.
VMware delivered its first product, VMware Workstation, in May 1999 and entered the server market in 2001 with VMware GSX Server (hosted) and VMware ESX Server (hostless).

Types of virtualization
Hardware virtualization
In computing, hardware virtualization is a virtualization of

computers or operating systems. It hides the physical characteristics of a computing platform from users, instead showing another abstract computing platform.
Hardware virtualizations splits in different types:
Full (Hypervisor) Virtualization
Paravirtualization
Partial Virtualization

Слайд 14

Types of virtualization
Hardware Virtualization is not the same as Hardware-assisted
Virtualization
In hardware-assisted

virtualization, the hardware provides architectural support that facilitates building a virtual machine monitor and allows guest OSes to be run in isolation.
The most famous technologies are:
AMD virtualization (AMD-V)
Intel virtualization (VT-x)

Слайд 15

Types of virtualization
Full (Hypervisor) virtualization
This model uses a virtual machine monitor

(hypervisor) that mediates between the guest operating systems and the native hardware.
The biggest advantage of full virtualization is that an operating system can run unmodified.
VirtualBox, Vmware Workstation

Слайд 16

Types of virtualization
Paravirtualization
This method uses a hypervisor for shared access to

the underlying hardware but integrates virtualization-aware code into the operating system itself.
Paravirtualization offers performance near that of an unvirtualized system.
XEN, VirtualBox

Слайд 17

Types of virtualization
Software virtualization
Operating system-level virtualization
This technique virtualizes servers on top

of the operating system itself. This method supports a single operating system and simply isolates the independent servers from one another.
OSL virtualization requires changes to the operating system kernel, but the advantage is native performance.
Virtuozzo, OpenVZ, Jail (FreeBSD)

Слайд 18

ADVANTAGES OF VIRTUALIZATION

Слайд 19

Advantages of Virtualization
Advantages of Virtualization
More efficient use of computer processing power
Less

energy consumption (a) Run ONE physical server instead of several (b) Less air conditioning usage to keep the environment intact (c) Less power backup resources required
End of endless hardware purchases and upgrades (a) All the hardware is virtualized so no need to purchase controllers (b) Hardware upgrades are on software level (memory, processor, or any controller) (c) No need to physically install hardware
Safer, faster backups and restore (a) Ability to take live snapshots while OS is running (b) You can schedule snapshots of OS (c) Less time to recover the whole OS
Reduced IT overhead.
Simplified IT Management from a remote location (from anywhere in the world using an Internet connection).
Ability to use Thin Clients (low-cost centrally managed computers devoid of diskette drives, CD players and expansion slots, and which require no hardware maintenance).
Ability to use existing computers for remote desktop connection to virtual machines located on the main server.
Faster server/client connection speed through a virtual switch.

Слайд 20

Advantages of Virtualization
Advantages of Virtualization for testers
Virtualization tools allow software testers to

quickly and easily set up and maintain testing environments, and to rapidly restore testing environments to their original state when required.
Ease of application deployment
It’s good for testing a virtual network. This would allow you to test out networking protocols.
Configuration testing, installation testing (different sets of OS’s and applications)
Experiment with potentially incompatible applications.
Perform testing with different user profiles.
Access / security / vulnerability / etc. testing with no effect to the normal working environment.
When finding a bug, a tester can simply save a system state, where the bug appears, to a snapshot and continue testing of the system. If it is necessary to reproduce the bug, the virtual machine can be given to a developer who can work with it without fear to damage tester’s environment. Besides, resources become available for further testing: the tester can continue working and not wait till the developer finishes with the test environment.

Слайд 21

Advantages of Virtualization
Disadvantages of the Virtualization Technology
Impossibility of emulation of all

devices. At the current moment, all main devices of hardware platforms are supported by vendors of virtualization systems. But if some controllers or devices, which are not supported, are used, we have to refuse the virtualization of such environment.
Virtualization requires additional hardware resources. Existing virtualization technologies make it possible to bring performance of virtual machines to real. But to start some definite configuration with a number of machines, we need a physical host to allow this.
Equipment conflict. Drivers used by a virtualization system can conflict with drivers of tested equipment.
In case of low disk space on the hard disk of the virtual machine, we cannot increase it if the virtual machine contains snapshots.
We should perform final testing of the developed software on real machines because no virtual environment can completely replace the real one.
There are training costs on work with virtual machines.
When a virus is detected on one of snapshots, it is hard to define on which stage it appeared. We have to check all snapshots because the antivirus that can detect and delete viruses on all snapshots of the virtual machine isn’t developed yet.
Single destruction point. If a virtualization system fails, it is impossible to start virtual machines till the reason of failure is found and system is recovered.

VirtualBox
Oracle VM VirtualBox is an virtualization software package, originally created by

software company innotek GmbH (initial release January 15, 2007), purchased by Sun Microsystems, and now developed by Oracle Corporation as part of its family of virtualization products. It is installed on an existing host operating system; within this application, additional guest operating systems, each known as a Guest OS, can be loaded and run, each with its own virtual environment.
Latest versions of VirtualBox:

Network Address Translation (NAT)
If all

you want is to browse the Web, download files and view e-mail inside the guest, then this default mode should be sufficient for you, and you can safely skip the rest of this section.
In computer networking, network address translation (NAT) is the process of modifying network address information in datagram (IP) packet headers while in transit across a traffic routing device for the purpose of remapping one IP address space into another.

Слайд 41

Virtual Machines: Create VMs in Virtual Box
Bridged networking
This is for more

advanced networking needs such as network simulations and running servers in a guest. When enabled, VirtualBox connects to one of your installed network cards and exchanges network packets directly, circumventing your host operating system's network stack.
Bridging is a forwarding technique used in packet-switched computer networks. Unlike routing, bridging makes no assumptions about where in a network a particular address is located. Instead, it depends on flooding and examination of source addresses in received packet headers to locate unknown devices. Once a device has been located, its location is recorded in a table where the MAC address is stored so as to preclude the need for further broadcasting. The utility of bridging is limited by its dependence on flooding, and is thus only used in local area networks.

Слайд 42

Virtual Machines: Create VMs in Virtual Box
Host-only networking
This can be used

to create a network containing the host and a set of virtual machines, without the need for the host's physical network interface. Instead, a virtual network interface (similar to a loopback interface) is created on the host, providing connectivity among virtual machines and the host.
Host-only networking provides a network connection between the virtual machine and the host computer, using a virtual Ethernet adapter that is visible to the host operating system. This approach can be useful if you need to set up an isolated virtual network.
If you use host-only networking, your virtual machine and the host virtual adapter are connected to a private TCP/IP network. Addresses on this network are provided by the product’s DHCP server.

Слайд 43

Virtual Machines: Create VMs in Virtual Box
For each card, you can

individually select what kind of hardware will be presented to the virtual machine. VirtualBox can virtualize the following six types of networking hardware:
AMD PCNet PCI II (Am79C970A);
AMD PCNet FAST III (Am79C973);
Intel PRO/1000 MT Desktop (82540OEM);
Intel PRO/1000 T Server (82543GC);
Intel PRO/1000 MT Server (82545EM);
Paravirtualized network adapter (virtio-net)
The Intel PRO/1000 MT Desktop type works with Windows Vista and later versions. The T Server variant of the Intel PRO/1000 card is recognized by Windows XP guests without additional driver installation. The MT Server variant facilitates OVF imports from other platforms.
The PCNet FAST III is the default because it is supported by nearly all operating systems out of the box, as well as the GNU GRUB boot manager. As an exception, the Intel PRO/1000 family adapters are chosen for some guest operating system types that no longer ship with drivers for the PCNet card, such as Windows Vista.

VirtualBox: Snapshot
A snapshot

Слайд 74

VirtualBox: Snapshot
A snapshot is a “point in time image” of a

virtual guest operating system (VM). That snapshot contains an image of the VMs disk, RAM, and devices at the time the snapshot was taken. With the snapshot, you can return the VM to that point in time, whenever you choose. All changes made after the snapshot was taken may be based on that snapshot information (incremental changes). You can take snapshots of your VMs, no matter what guest OS you have and the snapshot functionality can be used for features like performing image level backups of the VMs without ever shutting them down.

By default you can install only workstation-class

OS (Win7, Win8, Win10). To have server OS in VM you need to receive MSDN subscription to be on safe side from licensing point of view.
Oracle Virtual Box added as virtualization tool.
You cannot run a procedure in EPAM office that do not have server farm installed (London, Zurich, Boston, etc).
You cannot run the procedure from outside of office LAN (VPN will not help here).
Procedure is automated and simple enough.
You installed licensed copy of OS and software.
Virtual machine is properly configured and managed, i.e. security updates installed, antivirus running.
