What is happening to IT spending?

Forrester now exp ects a 10.6% decl in e in the global tot al

of business ' and gov ernments ' purch ases of comp uterand communicat ions equipm ent, sof tware, IT consul t ing

and integrat ion s erv ices, and IT outsourc ing in 2009 over

2008. Global purchases of com puter equipm ent wi l l be

dow n by 13.5%, and comm unicat ions equipm ent buying

wi l l dro p by 12.4%.June 29, 2009*

The US Department of Commerce data showed a 13%

drop in b usiness investment in routers, switch es, PBXes,

and other network equipment in Q1 2009, wh ich w as a

steeper decline th an the -4% grow th r ate in Q4 2008. The

vendor d ata showed an even bigg er 20% decl ine in

revenues from sales of these produ cts.

In January we forecasted a 3% decline IT purchases in US dollars;

we now are saying its a 10.6% decline for 2009

Why the worse outlook?

Q1 and Q2 2009 cuts in tech purchases were much deeper than we

expected, due in part to deeper recessions, but also due tobusinesses in the US, the UK, and several other markets cutting

capital investment way back.

How Are CIOs Reacting?

Most are facing budget and staff cuts

They are implementing projects to save money andimprove efficiency:

Server centralization, data center consolidation, server anddesktop virtualization

Unified communications (UC), IP videoconferencing, mobilityapplications

What do all these projects have in common?

Communications? Yes, but try again . . .

Much greater WAN bandwidth needs!

Stringent WAN performance requirements!

The Impact?

In 2009 network traffic is growing at 30% to 70% per annum


8/19


Applications Users

Server virtualization

Corporate network

Remote backups

New real-time applications

New, dynamic content

Data center consolidation

Major IT initiatives are stressing the

network causing a decrease in

performance and potential bottleneck

between apps and users

!

The result is both WAN cost escalation andapp performance problems

Internet


9/19


The solution? WAN optimization

WAN optimization technology can: Make the best use of your existing bandwidth

and solve your application performance problems

But first

You cant manage what you cant measure most

enterprises have under-invested in performance

monitoring

Start by understanding your WAN performanceeither use an in-house monitoring tool or buy a

service from your telco, then deploy WAN

optimization


10/19


WAN optimization helps with three keyfinancial benefits

Bandwidth

optimization

Free up bandwidth by reducing

data and eliminating

unnecessary roundtrips1

Infrastructure

consolidation

Consolidates branch services in

datacenters by accelerating

traffic from centralized locations2

Reduce

capital outlay

Allows shift of capital by

consuming application (SaaS)

and hardware (cloud) services3


11/19



Bandwidth

optimization

Free up bandwidth by reducing

data and eliminating

unnecessary roundtrips1

Avoid private WAN upgrades

especially on international links

Leverage lower speed links

where higher rate bandwidth iscostly or unavailable

Facilitate the migration to

cheaper Internet links

Examples

of savings


12/19



Centralize infrastructure services

like domain controllers, DHCP,

DNS, file, and print servers

Provide flexibility to consolidateapplication and remote storage as

a second tier

13/19



Shift expensive application

infrastructure and maintenance

costs to off-premise model

Consume on-demandinfrastructure on a utility model

like tier three storage/backup

Examples

How should you implement WANoptimization?

WAN optimization can:

Reduce bandwidth and optimize existing resources

Improve application performance

Solve problems resulting from data centerconsolidation, server centralization, Web servicesdeployment, etc.

Produce a return on investment in 8 15 months

But:

To impIement it in-house requires CAPEX, skilledimplementation resources, and ongoing management


15/19


The alternative? Look at WANoptimization managed services

No CAPEX

No implementation resources

No ongoing management

Choice of technologies

Available from all major telcos

May come with an application SLA


16/19


Why telco services make sense

Leverage telcos expertise in: WAN performance measurement & monitoring

Experience in choice of the best WAN optimization kit

Experience in WAN optimization implementation

Economies of scale

The result:

Using telco consulting and managed services you can

buy monitoring and optimization as a flexible service


17/19


What to look for in choosing a vendor - whatquestions should you ask?

WAN management service. Does the service offering includenetwork performance monitoring, performance reporting, andtraffic analysis?

WAN optimization service. Is the service customer premisesequipment (CPE)-based or network service-based, or both,

and which vendors' equipment do they support for theirstandard and custom services?

Device management, monitoring, and SLAs. Are theirdashboards integrated into their customer portals, and do theyoffer application-level SLAs?

Revenues, clients, and pricing. What are their currentrevenues, and how many clients do they have?

Global Reach. Can the service provider meet your geographiccoverage needs?


18/19


Recommendations

Dont ignore WAN optimization it works for almostall networks

WAN optimization will help you make the most of

your existing network bandwidth

Dont neglect tools and services for performance

monitoring and troubleshooting

Take a look at WAN optimization consulting and

managed services leverage the expertise of yourservice provider!
