History of Virtualization


Slide 4

IBM Introduces

Virtualization of

Mainframes

1960s

In the mid-1960s. IBM introduces the virtualization of mainframes. IBM implements virtualization as a way to divide the resources of a single mainframe computer into many smaller, independent virtual machines. This allows mainframes to run multiple applications and processes simultaneously. At a time when mainframes cost millions of dollars to own and operate, virtualization becomes a way to maximize computing resources and increase the Return on Investment (ROI).


Slide 5

1980s and 1990s

Internet

x86 Computers

Dominate

During the 1980s and 1990s, x86 computers dominate. During this time, the development of inexpensive x86 computers and the spread of the Internet lead to distributed computing as a dominant architecture. However, unlike mainframes, x86 computers were not designed to be virtualized and their operating systems didn’t, and still don’t, run densely stacked applications very well. What happens as a result of the x86 platform’s popularity? The popularity of the x86 platform results in the widespread adoption of a one-application-per-server architecture. However, this becomes increasingly wasteful of resources as the power of x86 computers continues to grow by leaps and bounds.


Slide 6

VMware Begins

1998

In 1998, VMware Begins. VMware was established in 1998 with the revolutionary idea of bringing virtualization and its benefits from the mainframe to the x86 computer. That same year, VMware files its first patent, "System and Method for Virtualizing Computer Systems."

1999

In 1999, VMware releases the first product ever to virtualize the x86 platform. VMware introduces Workstation 1.0 for Windows and Linux, creating a milestone not just for VMware but for computing as a whole.

VMware technology has now made it possible to run multiple virtual machines on a single x86 workstation for the first time.

In this way, VMware has dramatically increased resource utilization and the Return on Investment for the x86 platform, as virtualization had done for mainframes 30 years before.

Today,VMware has continued to be the principal pioneer in 21st century virtualization, expanding this technology to all levels of computing. Today, VMware is the global leader in x86 virtualization, with our technology powering 99% of the Fortune 1000 and 97% of the Global 500 companies. While others are just now jumping on the virtualization bandwagon with immature technology, VMware's flagship product is a 5th generation virtualization platform called vSphere. vSphere provides the ability to build and manage entire virtual infrastructures, with hundreds of interconnected physical computers and storage devices providing the resources for many thousands of virtual machines, including virtualized servers and desktops. All these form a virtual cloud of computing power that can potentially provide resources anywhere, anytime to many different kinds of devices. Cloud computing is a virtual technology that today is taking the world by storm, but VMware has been pioneering the technology for over ten years, and it continues to lead the virtual revolution.

How Does Virtualization Work?


Slide 13

What is a Virtual Machine?I am a

What is a virtual machine? A virtual machine is an isolated software container that runs its own operating system and applications as if it were a physical computer. It behaves exactly like a physical computer and contains its own virtual motherboard with a bios, serial ports, CD/DVD drive, CPU, RAM, hard disks, and network interface cards (NICs). An operating system loaded in a VM can’t tell the difference between a virtual machine and a physical machine, nor can applications or other computers on a network. Even the virtual machine thinks it is a “real” computer. Nevertheless, a virtual machine is composed entirely of software and contains no hardware components whatsoever.


Slide 14

On top of x86

hardware

On top of the operating

system

VMware Virtualization works by inserting a thin layer of software, either directly on top of the x86 hardware or on the operating system. This software generates virtual machines, supplying them with all the hardware resources they need.

set of files

Advantages

Encapsulation

A virtual machine (VM) is essentially a software computer with a complete set of virtual hardware, as well as an operating system and all its applications… …contained or encapsulated inside a discrete set of files. These files are kept in a directory on local, SAN, or NAS-based storage. They are stored in this directory when the VM is powered down and read when the VM is run. Encapsulation makes virtual machines incredibly portable and easy to manage. For example, you can move a virtual machine from one location to another, or clone it, just by copying its files, or you can backup a virtual machine on any standard data storage medium, from a pocket-sized USB flash drive to an enterprise storage area network (SAN).


Slide 17

Advantages

Isolation

VMs remain completely isolated

from each other.

=

Although virtual machines share the physical resources of a single computer, they remain completely isolated from each other as if they were separate physical machines. If, for example, there are three virtual machines on a single physical server and one of the virtual machines crashes due to a bug, the other two virtual machines remain available. This isolation also avoids the resource conflicts that cause performance problems when you start stacking demanding applications on a commodity operating system. Isolation is an important reason why the availability and security of applications running in a virtual environment can be equal to or better than applications running in a traditional, non-virtualized system.


Slide 18

Advantages

Compatibility

Virtual machines are completely compatible with all

standard x86 operating system and applications.

Operating System

Virtual Machine

Operating System

Applications

Just like a physical computer, a virtual machine hosts its own guest operating system and applications, and has all the components found in a physical computer. As a result, virtual machines are completely compatible with all standard x86 operating system and applications, so you can use virtual machines to run all the same software that you would run on a physical x86 computer. No modifications are required.


Slide 19

Advantages

Hardware Independence

VMs are completely

independent from their

underlying physical hardware.

You could move a VM from an

HP computer to a Dell and

expect the VM to run without

any modification.

VMs are completely independent from their underlying physical hardware. Their virtual components can be entirely different than the physical components that are present in the underlying hardware. Because of this, you’re free to run whatever OS and applications you’d like inside that VM without concern for its neighbor VMs or the physical host. You could, for example, move a VM from a host computer made by HP to one made by Dell and expect the VM to run without any modification. The VM moves with its virtual components and device drivers intact. Hardware independence gives the complete freedom to move a virtual machine from one type of x86 computer to another without making any changes to the device drivers, operating system, or applications.

The Virtual Infrastructure


Slide 24

THE VIRTUAL INFRASTRUCTURE

Encapsulated, isolated, hardware-independent virtual machines are the fundamental building blocks that form part of a much larger solution offered by VMware: the virtual infrastructure. In a generic sense, a virtual infrastructure lets you share physical computing resources across an entire datacenter and even across an entire enterprise. The idea is to aggregate x86 servers, along with their network and storage resources, into a unified pool that can be utilized by the applications when and where they’re needed. With the virtual infrastructure in place, business needs can now dynamically map the physical resources of the infrastructure to applications—even as those needs evolve and change. A business need can be met anywhere, anytime, and potentially on any computing device, regardless of the operating system or physical resources.

The first step

The virtual infrastructure therefore brings an enormous amount of flexibility in the organization, while producing significant savings in capital and operational costs. And the final result is greater satisfaction for everyone - for the internal customers whose business needs are getting met quickly, for IT whose costs are going down and positive feedback is going up, and for the organization, which is able to respond more rapidly and efficiently to its market. But the virtual infrastructure is only the first step toward the Cloud.

What is a cloud? First it is important to note what it is NOT. In today's world, a Cloud is not just a virtualized infrastructure, or a network where everything has been made virtual. A cloud is a virtualized environment that has been developed to provide self-service. Think of it as a high-tech vending machine where everybody in the company can go to get what they want, anytime, anywhere, from any device Let's say a developer wants a new database server. He goes up to the vending machine, puts in his credit card, presses a button and instantly, he gets the server. He also gets the receipt too, because he's been charged. A department head comes and says her team needs more computer resources--more hard drive space, more memory for their applications. She goes to the machine, presses the button, and instantly, she gets the resources she wants, and she gets the bill as well. No endless meetings between IT and different departments to figure things out for a particular project. No wait time. You go for it, you get it. That is what the Cloud delivers: Self-service for internal customers. Control and Manageability for IT.

PRIVATE PUBLICBridge

There are three main types of clouds: Private, Public and Hybrid. In the Private Cloud, the organization hosts all the hardware and software that produces the cloud. VMware provides all the software necessary to produce the most powerful, efficient and cost-effective private cloud possible. In the Public Cloud, the organization pays a third-party provider to host all the hardware and software that produces the virtual environment. The organization still has complete control over the administration of the environment, the virtual machines, and all the other components of the cloud, but a third party is running the datacenter producing that cloud. VMware has more than 18 partners worldwide who use VMware technology to host clouds for their customers. In the Hybrid Cloud, some parts of the virtual environment are hosted by the company and others by a third-party provider. One recent study has shown that the hybrid cloud will be the most cost-effective approach to IT. VMware technology bridges the public and private cloud to create the optimal hybrid environment, in which applications can be moved in and out of the public cloud as the need arises.

Cloud Services

SERVICES

Resource Pool

Catalog

IaaS

At a high level, there are three basic types of services that cloud technology can offer. Infrastructure as a Service, or I-a-a-S, is when an IT organization uses the virtualized infrastructure to provide pre-provisioned virtual resources through a catalog. Resources can be a server, a database, or an application. Policy-based automation ensures that while resources can be provisioned quickly, there’s no opportunity for human error or security loopholes. And with chargeback, IT can either charge users for resources or just provide reports summarizing the cost of resources used. With all of this together, IaaS allows IT organizations to leverage existing assets to provide resources with high availability, strong security, and excellent reliability.


Slide 33

SERVICES

Applications

PaaS

The next Cloud Service is PaaS, or Platform as a Service. Platform as a Service gives application developers a virtual platform for their programs. This allows developers to code their programs so that they run on the cloud and not on your local computer. The application would be optimized for the cloud, using resources from the cloud. And it would be totally transparent to the user. You could be running the program on your local computer and never realize that it's actually using the storage and memory resources of the Cloud.

The final type of Cloud Service is Software as a Service, or SaaS. In this case, the entire application and its cloud resources are hosted by someone else, and you access that application through a web browser. Google Docs and Amazon Cloud Music are examples of Software as a Service.


Slide 35


Cloud Computing: An approach to computing that leverages the efficient pooling

of on-demand, self-managed virtual infrastructure, consumed as a service.

Controlled

by

IT

We’ve seen how the virtual machines form the basis of the virtual infrastructure, and that this infrastructure provides a first step towards the cloud and all the services that it can provide. Bringing this all together, we can define cloud computing as the following: Cloud Computing is an approach to computing that leverages the efficient pooling of on-demand, self-managed virtual infrastructure, consumed as a service. So in Cloud Computing, the virtual infrastructure evolves into something that is self-managed and completely controlled by IT. Yet it’s entirely on-demand for the user, providing computer resources anytime, anywhere.
