3/45



Why virtualization ?

Its fun.

It gets a lot of papers published.

Its going to change everything. Eventually.

But the customer benefits boil down to just two things


4/45



Customer BenefitsVirtualization can help to manage cost

Virtualization enables distributed, automated system management Virtualization allows resources to be managed as abstract entities

Independent of physical instantiation, location even existence

Physical servers host multiple virtual servers

Virtual servers are objects that hide underlying complexity

Presents a common interface and architecture

Simplifies OS and system maintenance

Hardware abstraction

Virtual resources can be allocated and managed dynamically

Enables more efficient use of existing resources Manage such things as cost, QoS, power,floor space, cooling and security

Enhances scalability while controlling costs

Virtualization is the fundamental enabling technology for utility computingand utility services, both of which will reduce costs


5/45



Customer BenefitsVirtualization can help to manage risk

Virtual servers run in secure compartments Isolation is comparable to separate physical servers

Failures, even user and kernel errors, cannot propagate to other virtual servers

Individual applications can be mapped to separate virtual servers

Enhances security and separation

Avoids application incompatibility problems

Separation of virtual and physical resources facilitates availability

Transparent hot-swap component replacement and upgrades

Live virtual server migration for load management and maintenance

Low-cost redundancy

Virtualization provides a risk buffer for capacity planning

Under-provisioning to reduce expenses

Over-provisioning to ensure adequate capacity

Dynamic resource management can mitigate these risks


6/45



Example: Data Center Dilemma

Data center has physical constraints Fixed sized, fixed power, fixed cooling, etc Often physical constraints are cost prohibitive to change

Data centers have excess capacity Volume servers (Intel ISS) 10-15% utilized, mid / high 30-40% (>4 socket)

Customers comfortable with single application server One application per OS instance optimal unit of management, control, etc. Application stacking to consolidate on a single OS viewed as higher risk and

often more expensive Need a new service, deploy a new server / storage (ie VM warehouse model)

Dilemma Can no longer afford current paradigm

Cant afford the $10 million server or storage controller that translates intoa new data center or expansion

Cant afford continual increase in number of administrators or cost / time todeploy new services

Cant afford power and thermal management e.g. Annual electric bill for Googles 200K servers greater than cost of

all server hardware

8/45



Multiplex one machine into different Virtual Machines VMs; allows running differentisolated guest Operating Systems with different applications on same physicalhardware.

Allows a Guest OS to run

under control of a supervising

master program that is called:

Hypervisor or Virtual Machine Monitor (VMM). Hypervisor / VMM Functionality:

Virtualizes System Resources

Provides Scheduling of host/guests

Intra-guest communication

Common grounding

'Host' also often referred as 'dom0' and/or HyperVisor

'Guest' also known as 'domU'

Hypervisor/VMMHardware
