IntroductionIntroduction

Server

machine that host file and application.

Usually dedicated to an application.

Server VirtualizationServer VirtualizationAllows multiple operating instances to

run concurrently.

Creating multiple logical server OS instances on one physical piece of hardware

TypesTypesFull virtualization

Para virtualization

OS-level virtualization

Full VirtualizationFull Virtualization• It uses special kind of software called HYPERVISOR.•It runs multiple applications simultaneously.

Para VirtualizationPara Virtualization• every guest is aware of other guests server’s.

Fig: Para virtualization

OS level VirtualizationOS level Virtualization• No hypervisor used here.•Has a homogeneous environment.

ApplicationsApplications

Virtual Private Server.

Parallel OS environments.

Virtual Private Server.Virtual Private Server.• Running different guest on the same physical server.• Cost Effective• Less expensive

Fig: Virtual private server

Single Physical Server

Parallel OS environments.Parallel OS environments.Can run different OS services independent of

the server used.

Linux Server

Windows Server

SharePoint Server

Parallel OS Environments

LimitationsLimitationsNot suitable for application

requiring high processing power

Not suitable for limited disk space hard drives

Migration is another problem for different processors

ConclusionConclusion

Server virtualization is a strategic direction for managing servers.

It reduces the cost of hosting and managing servers

Managing a pool of identical servers simplifies operating procedures.
