Virtualization

What Is Virtualization ?

• Virtualization is a Technology that transforms hardware into software.

• Virtualization allows to run multiple operating systems as virtual machines.– Each copy of an operating

system is installed in to a virtual machine.

Types of Virtualization

Full Virtualization

Full virtualization uses a special kind of software called a hypervisor. The hypervisor interacts directly with the physical server's CPU and disk space. It serves as a platform for the virtual servers OS.

Para Virtualization

The para-virtualization approach is a little different than the full virtualization

technique, the guest servers in

a para-virtualization system are

aware of one another.

Virtualization Allows Transformation of a Server for Multiple Applications

Server Virtualization

Server Virtualization

• The VMs created on one physical server can be run another physical server.

• Failure in one physical server will not effect the VMs installed on that.

Storage Virtualization is the next frontier in Storage Advances that aims to provide a layer of abstraction to reduce complexity

Storage Virtualization

Software virtualization is

the virtualization of applications or computer

programs

Cloud VirtualizationTechnology

INTRODUCTION Virtualization represents the logical view of data representation- the power to compute in virtualized environments.It is a technique that has been used in large mainframe computer for 30+ years. It is used to manage a group of computers together- instead of managing resources separately.

Cloud Virtualization Technology

Virtualization DefinedVirtualization is an abstraction layer that decouples the physical hardware from the os to deliver greater IT resources utilization and flexibility.Virtualization can bring the following benefits ● save money● increased control● simplify disaster recovery

Cloud Virtualization TechnologyBenefits

1. Traditional benefitsa) server consolidationb) “Green IT” - reduced power and cooling2. Additional Benefitsa) increased availability/business continuity

and disaster recoveryb)efficient application and desktop

software deployment andMaintenancec) dynamic and extensible infrastructure to rapidly address new business requirements

Current Virtualization InitiativesHere is a list of different virtualization initiative actively pursued in industry Today● Virtual Networking● Virtual Disk● Consolidated management● Vmotion● Svmotion● Dynamic load balancing● Zones

Cloud Virtualization Technology Virtual Machine

Often called Virtual environment or container. A Virtual machine is a server environment that does not physically exist but is created within another server.For user interacting with a VM is seen or presented as a physical machine providing access to an operating system and machine resources like CPU memory, hard disk and network.

Cloud Virtualization TechnologyVirtualization Technologies

Two major types of virtualization technologies widely used are● Hardware Virtualization ○ virtualizes the server hardware● OS virtualization ○ virtualizes application environment

Cloud Virtualization Technology Hardware based Virtual Machine

(HVM)

● Hardware based Virtual Machine or Hardware assisted Virtualization ( HAV) is done possible by using new features developed by Intel and AMD● These new features include Intel Virtualization Technology (VT-x) and AMD’s AMD-V

OS Level Virtualization

An OS-level virtualization

approach doesn't use a hypervisor

at all. Instead, the virtualization

capability is part of the host OS,

which performs all the functions of a fully virtualized

hypervisor

Detailed DesignIt introduces many changes into theenvironment, and ensures that the platform can co-exist and interact with existing infrastructure.The purpose of detailed design to set naming and security standards, define the disk and network structure. It includes the following● Security and Administrative Model● Back up methodology● VMware service console configuration● implement tables and configuration setting

Summary

This focuses on cloud virtualization and also covers other flavours of

virtualization. It also covers software components used for

managing virtualization process entirely…….
