About ZK Research • Founded by 10+ year veteran industry analyst Zeus Kerravala • Exclusive focus on network and communications technology that are in market transitions • Background on Kerravala • 10+ years as a Yankee Group Analyst and remains an Affiliate of YG • 10+ years in corporate IT and consulting • Holds many technical certifications
ICT Defined • The integration of Information Technology and Communications • Historically these have been separate operations within companies • ICT is being driven by current IT megatrends “Virtualization, cloud and mobility are transforming every part of IT. To maximize the potential of virtualization, the network must also transform.”
The CIO Mandate is Changing “… need a solution that enables us to respondto customers within hours instead of days” “I need to achieve greater cost efficiencyandincreased IT agility…an elusive combination…” “At the end of the day, I just want to simply, confidentlysay “yes”to my business.”
A Perfect Storm is Underway Consumerization of IT Device Evolution ICT Virtualization and Cloud Wireless Advancements Growing Mobile Workers Tablet Computing
Computing is Becoming More Network Centric Network Value Mainframe Client/Server Internet Mobile/Cloud 1960-1980 1980-1995 1995-2010 2010+ • Each Wave of Computing: • Increased the value of the network • Lowered the cost of computing • Increased the integration of the network and IT infrastructure Cost of Computing
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 BYOD Cloud Computing Endpoints on the network MDM Mobile Apps Complexity Chasm Virtualization UC Wireless Access IT Budgets Building blocks of IT
The Current State of IT is Not Scalable 90% 37% of IT projects are delivered late or cancelled of network downtime is due to human error 75% 83% of problems are identified by end users, not through the IT department of a companies network budget is used to “keep the lights on”
Consumerization Drives the Market to ICT What is your Company Attitude on the Use of Consumer Technologies No Tolerance 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 High Acceptance
End User Toolkit Then and Now Toolkit Then Toolkit Now
BYOD Increases Productivity In the context of workplace productivity, please rate your agreement with the following statements. • 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 Survey of NA based corporate workers
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.
ICT Enables True Mobility • The IT perfect storm leads to true mobility • Applications become context aware, intelligence delivered from the network • ICT puts the network at the center of IT strategy
Key Trends Impacting the Data Center Reduce Cost and Raise Productivity IT as a service Applications availability Green IT—power, cooling and space Server virtualization — higher performance Network and storage convergence VM-Level awareness Workload provisioning
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 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 • 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
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 • Inconsistent or poor user experience • Wireless overlay has a high total cost of ownership • Wireless network needs to take on “wired” characteristics • Access network is optimized for wired connectivity • Wireless is for convenience, not continuous access • No integration with wired network
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
Wireless LAN Evolution 4thGen WLAN Integrated Wireless 100K+ devices 3rd Gen WLAN Wireless Overlay 10K+ devices 2nd Gen WLAN Enterprise standard fat APs Hundreds of devices 1st Gen Devices Supported 1st Gen WLAN Ad Hoc Deployment Tens of devices
Benefits of Integrated Wireless LAN • Lower TCO • Deployment flexibility • Secure solution • Green solution • Centralized control • Better asset 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
