Virtualization 101

MAKING SENSE OF VIRTUALIZATION

Dale Philips, MCPc Managing Director Converged Networks Group

Introduction

• Virtualization has come a long way but the need remains the same.– IT professionals require controlled, secure and centralized

management of their business-computing environments.

• Technology has become a more integral part of modern business operations.– Companies have incorporated more hardware into their

office environments.

• Processing power has increased and physical units are taking up a disproportionate amount of space, time and money.

Global Perspective #1

“IDC recommends that business leaders and IT professional closely monitor – and perhaps even map – the impact that changing business requirements impose on IT services and assess how rapidly evolving IT technologies and new IT business models (e.g., virtualization, next-generation datacenters, cloud computer and second-generation ERP systems) will be deployed. IDC further recommends they re-evaluate IT investment strategies with an eye to taking advantage of flexible financing options that can preserve precious capital and reduce technology obsolescence.”

Global Perspective #2

“The professional desktop PC market is the most-exposed segment, with alternative architectures such as application streaming, hosted virtual desktops (HVDs) and blade PCs already resetting enterprise expectations of the client computing devices that are permanently connected to their networks. By moving some or all application executions to the data center, enterprises see an opportunity to pursue capital and operation cost savings by buying and deploying thinner, less capable desktop devices. However, deployment of HVDs requires initial high-cost investments in the server and network infrastructure.”

The Need for Virtualization

• Low infrastructure utilization• Increasing physical infrastructure costs• Increasing IT management costs• Insufficient failover and disaster protection• High maintenance end-user desktops

Too Much Complexity in Today’s IT

Cause– Overwhelming

complexity– Reliance on brittle

infrastructure

Effect– More than 70% of IT

budgets are spent on “maintaining” the status quo.

– Less than 30% goes toward innovation and competitive advantage.

So What is This Cloud Thing?

Cloud computing is a way of doing computing

EnterprisesCloud

Service Providers

Bridging

Private CloudOperated solely for an organization, typically within the firewall.

Hybrid CloudComposition of 2 or more interoperable clouds, enabling data and application portability.

Public CloudAccessible over the internet for general consumption.


Cloud Computing• Cloud computing is an approach to computing that leverages

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

Types of Virtualization

• Server• Application • Desktop


Server Virtualization Definition

• Masking of server resources (including the number and identity of individual physical servers, processors and operation systems) from server users.

• Intent is to spare the user from having to understand and manage complicated details of server resources, while increasing resource sharing and utilization and maintaining the capacity to expand later.

Application Virtualization Definition

• Umbrella term that describes software technologies that improve portability, manageability and compatibility of applications by encapsulating them from the underlying operating system on which they are executed.

• A fully virtualized application is not installed in the traditional sense, although it is still executed as if it is.

• The application is fooled at runtime into believing that it is directly interfacing with the original operating system and all the resources managed by it, when in reality it is not.


Virtualize the Applications

• How does it work?– Decouple applications and data from OS– Agent-less architecture– Wide platform and application support– Plug into existing app management tools

• Leverage benefits of isolation, encapsulation and mobility to applications on the desktop


Virtualizing Enterprise Applications

• Exchange• Oracle• SAP• Sharepoint• SQL

Tier 1 Applications can be Virtualized!


Desktop Virtualization Definition

• Server-centric computing model that borrows from the traditional thin-client model but is designed to give system administrators and end-users the best of both worlds: the ability to host and centrally manage desktop virtual machines in the data center while giving end users a full PC desktop experience.

• The user experience is intended to be identical to that of a standard PC, but from a thin-client device or similar, from the same or remotely.


Desktop Virtualization Objectives

• Streamline desktop management and deployment• Deliver built-in business continuity for the desktop• Ensure security with centralized control and

management
