ICT Defined

“Virtualization, cloud and mobility are transforming every part of IT. To maximize the potential of virtualization, the network must also transform.”

• The integration of Information Technology and Communications

• Historically these have been separate operations within companies

• ICT is being driven by current IT megatrends


The CIO Mandate is Changing

““I need to achieve greater cost I need to achieve greater cost efficiencyefficiency andand increased IT increased IT agility…an elusive combination…agility…an elusive combination…”

“… “… need a solution that enables need a solution that enables us to us to respondrespond to customers to customers

within hours instead of days”within hours instead of days”

““At the end of the day, I just At the end of the day, I just want to simply, confidentlywant to simply, confidently say say

“yes” “yes” to my business.”to my business.”

Cost of Computing

Each Wave of Computing: •Increased the value of the network •Lowered the cost of computing •Increased the integration of the network and IT infrastructure


IT Complexity is on the Rise

•BYOD is dependent on several IT functions working together raising the bar on complexity

•Access, security, virtualization, UC

•Users expect a seamless, consistent user experience

•Consumer devices remove a significant element of IT control

•IT needs a better operating model to keep up with LOB demands

The Current State of IT is Not Scalable

37%37%of network downtime is due to human error

90%90%of IT projects are delivered late or

cancelled

83%83%of a companies network budget is used to “keep

the lights on”

75%75%of problems are

identified by end users, not through the IT

department


Consumerization Drives the Market to ICT

No Tolerance

High Acceptance

Do not allow any consumer devices

We allow it but provide no support

Consumer devices are allowed with limited support

Allowed with full IT support

BYOD Increases Productivity

• On average, workers use 4 consumer tools in their workday

• Workers believe they are more productivity because of BYOD

• Users also believe consumer devices are better than corporate technology

• Workers are no longer afraid of technology

In the context of workplace productivity, please rate your agreement with the following statements.

The Network is the Foundation for the Connected World

•The network is the most cost effective, scalable delivery platform for services

•Organizations should structure their application and compute strategy around the network

•Consistent user experience is a must across campus, branch and mobile edge

•User experience is network dependent

•The network is the best place to control and secure user sessions and experience

•Leveraging the network allows IT to say “yes” to LOB more often with better results.

Data Center Network is the Virtual Backplane

• Data center resources will be located in virtual pools

• The network is the connectivity fabric between the virtual pools and the application layer

• The network takes on the role of being the “virtual backplane” of the modern data center

• The network can provide orchestration and security services

• Application performance visibility can be gained through the network lens


Limitations of Current Data Center Networks

• Three tier architecture has too much latency to support real time and large workloads

• Spanning Tree Protocol (STP) leads to inefficient network infrastructure usage

• Traditional technology is not designed for virtual or cloud environments

• Poor management tools and high up front cost drive up TCO


Data Center Networks need to be Simplified

Traditional Network

Fabric


Network Fabric Defined

• Flat network• Every port virtually

connected to every other • Active / active switching • High speed network; 10

Gig-E, roadmap to 40 Gig-E and 100 Gig-E

• Operationally simple • Optimized for virtual

traffic and east west traffic flows

• Optimized packet processing


ICT’s Impact on the Data Center

Yesterday Today Tomorrow Clearly defined silos

Forced integration of silos

Converged infrastructure mandates no silos

Low infrastructure utilization (30%)

Improved utilization (50%)

Optimized utilization (70%+)

Virtualization for server consolidation

Virtualization for limited automation

Virtualization enables fully automated data center

No orchestration between servers, storage, network and applications

Script based or “manual” orchestration

Programmable interfaces enables seamless automation

People are 40% of TCO



Provisioning time = months

Provisioning time = days

Provisioning time is instantaneous


ICT Drives the Shift to SDNs• Allows for the network to be in better

alignment with the current data center trends

• Brings a high level of agility to the network

21

• Enables programmability

• Improves application performance

• Abstracts the control layer from the network infrastructure lay

• Compliments fabrics • Creates scalable

network virtualization


OpenFlow Defined

• The communications protocol used at the interface between the control and forwarding planes

• Traffic flows used for control of network • Can provide a common interface between the controller and the physical/virtual infrastructure

• OpenFlow is part of SDNs but not a necessary component


Understanding OpenStack

• One of the competing methods to deliver an SDN

• Collaborative effort of developers and cloud companies to create a single cloud operating system

• Used for orchestration of resources

• Brings compute, network and storage together

• Virtual infrastructure operates better together with OpenStack

Access Edge Trends


ICT Drives Towards a Wireless Edge

•Wireless LAN is moving from an augmentation to the primary network

•Needs to provide the same characteristics of the wired network

•User experience needs to be consistent across the enterprise


Challenges With Current Network Architecture

• Access network is optimized for wired connectivity

• Wireless is for convenience, not continuous access

• No integration with wired network

• Inconsistent or poor user experience

• Wireless overlay has a high total cost of ownership

• Wireless network needs to take on “wired” characteristics


Limitations of Legacy Wireless LAN

Limitations of traditional WLAN

•Overlay to wired network

•Inconsistent policies with wired network

•Shared medium

•Poor performance

•Complex management

•High cost of expansion

•Scale limitations

Legacy Wireless

Benefits of Integrated Wireless LAN• Lower TCO • Deployment

utilization• Moves enterprise

closer to pervasive wireless


The Urgency Around ICT • Network centric computing trends are

raising the strategic value of the network • New buying centers are having influence on

the network – virtualization, compute, line of business, C-Level

• This trend has been noticed by vendors up the stack – Oracle / Xsigo / Acme, VMWare / Nicira, Brocade / Foundry, IBM / BNT, HP / 3Com

• ICT is reshaping IT by removing silos, improving utilizations and enabling new functionality

• The shift is closer than you think


Recommendations

• Embrace the change, don’t fear it – it will happen with or without you

• Learn to speak “up the stack” • The status quo breaks at points of

market transitions – re-evaluate all your vendor relationships

• Integrated solutions can provide faster time to market, with lower risk and better results

• Take a vertical approach to leverage ICT • Use the uncertainty in the market to

break away from competition
