IT executives, industry analysts, and othersspeaking at an Interop roundtable on the con-sumerization of IT generally agreed that bothbusiness unit leaders and end users are provi-sioning their own applications. However, oneanalyst didn’t see it that way: “Are you seri-ous?” he asked. “Are users even capable of pro-visioning their own apps?” I think they are. With Millennials—those tech-

nology natives now entering the workplace—it’s not surprising that someone who gets hiredin marketing or sales might be able to config-ure an application. Web apps aren’t rocket sci-ence. It’s not as if these folks are doing devops.Consumerization is banging down the door

of IT, but IT isn’t always answering. “When areCIOs going to get it?” one vendor wondered ina side conversation. Well, the CIOs I talk with do

get it, but they’re vastly outnumbered by theirstaff members, who don’t necessarily get it yet.CIOs must take the time to educate staff inwhat consumerization is, why it’s not goingaway, and how it may even make their liveseasier and better. What if IT pros could actuallyfocus on business problems and apps insteadof spending so much time on infrastructure?During a discussion of the risks of consumer

devices and cloud computing adoption, I men-tioned the “helicopter parent” comparison weused in our recent Trifecta Of Change: 2011 EndUser Device Survey InformationWeek Analyticsreport. The question was: Does IT actually elim-inate risk with its smothering control, like a hel-icopter parent, and can IT ever eliminate risk?Maybe IT should chill out a bit and be open toaccepting some risk when business owners saythe benefits are huge. The group also discussed whether qualifica-

tion criteria for sensitive documents is practi-cal. That is, can data be classified in such a waythat inappropriate data isn’t shared outside ofthe organization? There wasn’t a tremendousamount of consensus on this point, which

makes me think it’s going to be an ongoing is-sue. An attendee said the cloud “might forceIT to at least look at data that needs protec-tion.” Indeed.The discussion quickly moved to security. En-

terprise security model changes might includelayering, risk mitigation, and segregating anddividing data. “Find out what really matters andsecure that,” one attendee said, implying thatin this brave new world, perhaps not everythingcan be fully secured. It might be as much about“risk acceptance” as “risk management.”I found the discussion about acceptable use

policies excellent. One analyst spoke of helpingcraft policies for companies that let employeesuse their own consumer devices to handle com-pany data but also give employers the right towipe that data and remotely monitor the per-sonal device. If you take this approach, run it byyour attorneys and make sure to get individualemployees to sign off.

Amazon Web Services’ recent outage was amuch discussed topic in the hallways, meetingrooms, and watering holes of Interop 2011.“It’s like an airplane crash. It’s very bad becausea lot of people are hit hard. But you’re actuallysafer in an airplane than in a car,” said SimonCrosby, Citrix Systems’ CTO for data center andcloud, speaking at a panel discussion. “Broadlyspeaking, you are better off in the cloud.”Where people make a mistake with the cloudis thinking it’s anything other than standard ITinfrastructure. “A lot of people think it’s magic,”said panelist Andy Schroepfer, VP of enterprisestrategy at Rackspace, an infrastructure-as-a-service supplier. “People think, ‘They wouldn’tsell me a ser vice that wasn’t backed up.’ ” Instead of that mind-set, customers need tounderstand their cloud service supplier’s archi-tecture, identify weak points, and figure out anacceptable strategy should their section of thecloud data center fail.Amazon’s SLAs didn’t cover the loss of its stor-age and relational database services, noted

panel moderator David Berlind, chief content of-ficer for UBM TechWeb, InformationWeek’s par-ent company. It covers only the running in-stances, not related ser vices, though Amazondid credit customers for the outage, whichlasted three days for some, by offering 10 daysof free service in EC2.“For websites such as Groupon and Reddit.com, is that really enough?” Berlind asked.The damage caused by the outage to an e-commerce site has to be balanced against thebenefits the site gains in the cloud, Schroepfersaid. Most sites do five times their normal busi-ness at the year-end holidays. By being locatedin the cloud, they don’t need to overprovisiontheir data centers with five times the amount ofcomputing needed in the other 11 months.Crosby offered a more pointed response:“Groupon and Reddit.com wouldn’t exist ifthere wasn’t a cloud.” They’re built on low in-frastructure budgets that get the computingpower they need through infrastructure-as-a-service suppliers, such as Amazon, he said.

Randy Rowland, senior VP of product devel-opment at Terremark, now part of Verizon Busi-ness, said cloud customers should negotiatethe SLAs they need with their cloud suppliers.”We define the SLA up front to meet a com-pany’s goals,” he said. Terremark and supplierssuch as Savvis aren’t known as low-price sup-pliers. They provide assigned account man-agers, guarantees that are higher than Ama-zon’s 99.95% uptime, and special recoveryservices, and that all comes at a higher price.Customers’ exposure to failure will be basedon the type of cloud suppliers they choose andthe relationship they build with those suppliers. “You’ve got to develop the relationship. Ifthere’s an outage and you don’t know who tocall, there is no relationship,” said Schroepfer.

The coolest thing on the Interop floor wasn’tthe Lamborghini or mechanical bull. It was theOpenFlow Interoperability Lab, where 16 ven-dors—Big Switch, Broadcom, Brocade, Citrix, Dell,Extreme, Fulcrum, HP, IBM, Juniper, Marvell, NEC,Netgear, Net Optics, Opnet, and Pronto—wererunning products, nearly all proofs of concept.It’s that kind of innovation that reminds IT prosexactly why we do what we do. And, in an erawhen standards events tend to be closed-dooraffairs for fear of bad press, a public lab shows arefreshing commitment to transparency.OpenFlow is an open standard that, when in-stalled on Ethernet switches, routers, and wire-less access points, separates the control planefrom the forwarding plane. The switch still doesthe forwarding, but the path through the net-work is determined by a controller. The Open-Flow protocol defines communications be-tween the edge devices and the controller.Network managers are no longer beholden toSpanning Tree, and can do new and interestingthings with routing and switching using inno-vative applications built on top of OpenFlow. A

major proof of concept will come in the formof the OpenFlow-based Network Developmentand Deployment Initiative, launched by Inter-net2 and several universities to support globalscientific research. The spec is supported by thenonprofit Open Networking Foundation, whichcounts some big names among its 34 mem-

bers, including Facebook, Google, HP, IBM, Mi-crosoft, and VMware. Cisco signed on to theONF just before Interop, a move that surprisedmany, given the organization’s goal of “soft-ware-defined” networking. “Ultimately, the vision here is that you’d actu-ally buy your components from a lot of differentvendors and stitch them together yourself, soyou can do a best-of-breed type of thing,” said

Big Switch Networks co-founder Kyle Forster inan interview at Interop. Forster says OpenFlowempowers IT in three main areas: virtualization,advanced forwarding, and programmability. “A highlight is these incredibly simple APIsthat you can start tying to your applications,”he said. “Rather than doing Radius, you can godirectly to Active Directory. Really simple.”Forster’s company is a member of the ONFand is based around the concept of networkvirtualization, the idea that OpenFlow will en-able IT to easily mix and match edge gear fromany number of vendors and manage the net-work as one big switch—thus the name. ThinkVMware for the network. For switch vendors, the protocol raises fearsof the dreaded “white box” effect. “If we’re using OpenFlow controllers andswitches to do the same stuff that switches dotoday, this is going to commoditize switching,”said Forster. “The real opportunity is to make thenetwork do more than what it does today; thenI believe that margins will stay just fine.”

Better VM Management The Best Of Interop overall honors went toVMware’s vCenter Operations Standard 1.0. Itboldly combines the data center disciplines ofsystem configuration, performance manage-ment, and capacity management into one man-agement tool and applies it to the private cloud.Granted, vCenter Operations, which also

took top honors in our cloud computing andvirtualization category, is aimed at virtual ma-chines, not hardware devices, and that’s the

departure point from its systems manage-ment predecessors. But the virtual world hasneeds that the physical world of systemsmanagement is ill equipped to handle, suchas relating the configuration of a VM to the ca-pacity—or lack of it—on a set of host serversand then managing those VMs as they movearound. VCenter Operations shows thatVMware has the vision, breadth, and grasp ofwhat’s needed. VMware already has tools, such as vCenter

and vSphere, to get VMs provisioned, run-ning, and moved around. VCenter Opera-tions draws information out of them andfeeds it into a powerful analytics engine.VCenter Operations can compare currentoperations to baseline statistics, de finingwhat’s normal for its complex environment.Instead of issuing alerts and cryptic mes-sages, it assigns green, yellow, or red sym-bols to indicate whether a server is work-ing properly, having problems, or unusablein three categories: workload, health, and capacity. VCenter Operations can detect when per-

formance has fallen below a norm. It can lookinside a host to see how each VM is perform-ing, and it can detect whether the host isoverloaded. If we’re moving toward a userself-provisioning environment, tools likevCenter Operations are going to be needed.

VideoconferencingOn The Go VidyoMobile extendshigh-quality videoconfer-encing to mobile users whowill increasingly demand it.Especially as we move intoa 4G world, video is goingto be one of the most im-portant mobile applica-tions, and Vidyo’s ability todeploy its client directly oniOS and Android smart-phones and tablets repre-sents a powerful rec og ni -tion that enterprise video isgoing mobile. VidyoMobile,the Best Of Interop collaboration winner, is animportant step toward enabling enterprisemobility.One of the biggest challenges to mobile

video is the potential for in-consistent quality. Here, too,VidyoMobile takes a com-mendable step forward.Vidyo’s Adaptive Video Layer-ing architecture delivers high-definition 720p video onsmartphones and tablets. Thisis critical, especially in busi-ness environments, wherelower-quality video and au-dio constrain widespreadadoption.In short, VidyoMobile will

let companies quickly andefficiently deploy a high-quality, bandwidth-efficient

video client to smartphones and tabletsacross the enterprise, helping to drive adop-tion of mobile video.

Network Design Rethought The NEC ProgrammableFlow switch, theBest Of Interop winner in the infrastructurecategory, advances networking technology ininnovative ways. It incorporates OpenFlow, aprotocol that lets a centralized controller ma-nipulate the forwarding tables on switchesand routers. Centralized control radicallychanges the way networks are designed andmanaged by reducing the number of routingand switching protocols in use. OpenFlow alsoenables new techniques like easily managingphysical and virtual machine mobility.The PF5240 is a hybrid switch that supports

both OpenFlow and native switching androuting simultaneously so administrators cansegment a portion of the switch ports toOpenFlow control and the remainder to na-tive control. With this hybrid approach, Open-Flow can be used for switch ports when itmakes sense and for traditional switchingand routing otherwise. The real power of theProgrammableFlow switch becomes appar-ent when, through a controller, you can virtu-alize the topology of Layers 2 and 3 regard-less of the underlying physical layout andvisualize the network paths. The OpenFlownetwork can be further segregated to accom-

modate multiple tenants, each of whom canmanage their own virtual network.OpenFlow and PF5240 improve on band-

width reporting of traffic trends. Unlike flow-based monitoring, they report vital stats onflows rather than just a sampling, providing amore accurate picture of network and appli-cation behavior.PF5240 is a 48-port 10/100/1,000-Mbps

switch with four 10-Gbps SFP+ uplinks. It hasall the switch functions you’d expect to see ina top-of-rack switch, including redundantpower supplies, remote management, routingfeatures, and IPv6 support. —Mike Fratto

Data Center BlueprintAlcatel-Lucent is clearly exploiting its dec -ades-long history as a telecom and ISP sup-plier in developing its data center switchingblueprint, which includes an innovative edgenetwork mesh and companion switch for anMPLS-compatible core coupled with manage-ment software designed for today’s virtual-ized workloads.Co-finalist Mellanox won the edge-switch

speeds-and-feeds battle with its impressiveSX1036 10/40-Gbps Ethernet device, but Alca-tel-Lucent prevailed by providing plenty of 10-

Gbps edge capacity, an edge mesh supportingmore than 200 server ports, a “pod” architectureextensible to more than 14,000 ports at multiplesites, and a management stack with virtual net-work profiles that can bind network configura-tion to virtualized applications and follow themas they migrate throughout the infrastructure—both within and between data centers. The pod design lets network managers start

small, with a mesh of six Omniswitch 6900edge devices, and grow into a multisite fabricusing Alcatel-Lucent’s OS 10000 core routers.Because it uses Shortest Path Bridging and is

compatible with MPLS WANs, the fabric canspan multiple data centers and even publicISPs and cloud providers. This incremental, modular architecture is an

important factor distinguishing Alcatel-Lucent’sdesign from that of the other co-finalist, Ju-niper’s QFabric. While both provide flat, high-performance, massively scalable networks,QFabric seems more appropriate for a whole-sale data center redesign, as it requires a greaterarchitectural, hardware, and budgetary commit-ment to deliver on the promise of a single, flat,yet highly scalable network. —Kurt Marko

Enterprise Access For iPhone, iPadAs mobility sweeps through the enterprise,users are demanding access to key applicationsusing an ever-widening array of smartphonesand tablets. It’s this trend that Citrix hasplugged into with its Receiver for the iPhone, afourth-generation iOS application that sup-ports both iPhone and iPad access. It took tophonors in our Best Of Interop mobile and wire-less category. This release complements Citrix Receivers

for other mobile platforms, including An-droid, BlackBerry, and Windows Mobile. It’s aneasy-to-install application that delivers se-cure, seamless, and consistent on-demand ac-cess to corporate data, business apps, and

desktops. All Receiver imple-mentations share a similar lookand feel.The Citrix Receiver for the

iPhone gives Apple users theability to access Citrix’s virtualdesktop and any Windows,Web, and software-as-a-serviceapp. It offers one-tap connect toread, create, and share docu-ments, and it provides a rangeof useful features, including anon-screen virtual track pad and,if used with iOS, the ability to use a separateiPhone as an external track pad via Bluetooth. The interface automatically adjusts for con-

nection bandwidth, whether you’reusing it over Wi-Fi, 4G, 3G, or eventhe slower Edge network. To ensuresecurity and regulatory compliance,no data is stored on the mobile de-vice itself, since the apps are oper-ated remotely at the data center.The Citrix Receiver for the iPhone

was chosen for its consistent, simpleimplementation across this andother platforms, and its ability tofoster business mobility. It can bedownloaded for free from the

iTunes store or from any private app store youoperate through a mobile device manage-ment system. —Mike Finneran

WAN Performance For LessWhile WAN performance is a top priority formost businesses, price is also part of theequation. The Talari Networks Mercury T750can help frugal IT shops cut costs by lettingthem move off private WANs and onto securepublic Internet connections without taking aperformance hit.The winner in the Best Of Interop perform-

ance optimization category, the T750 com-bines multiple sources of inexpensive public

Internet connectivity to deliver reliable, busi-ness-class performance, drastically reducingWAN costs.The T750 operates public Internetconnectivity in parallel, letting companies tapinto inexpensive bandwidth that was previ-ously unusable because of performance andreliability concerns. As a result, WAN businesscustomers gain 30 to 100 times the band-width per dollar, can reduce monthly WANservice costs by 40% to 90%, and get more re-liable and predictable application perform-

ance than existing private WANs that use sin-gle-provider frame relay or MPLS.Talari can continuously monitor the state

of available networks, using all the band-width most of the time and redirecting traf-fic to alternate paths in less than a second.Customers end up using public WAN band-width in a way that achieves performanceand predictability equal to or better thanthat of private WAN bandwidth.

Security For EveryoneSecurity technology seldom fits right. Manytools are designed for consumers, while oth-ers are geared for Fortune 1000 businesseswith deep pockets. Companies in the mid-dle—that is, most companies—end up havingto shoehorn security products to fit theirneeds or provide a lot of extra padding. Enter Barracuda Flex, our security winner. It

provides a package of products companiescan tailor to their technological and budget-ary needs. The technologies offered aren’t rev-

olutionary, but there’s some genius in the waythey’re packaged and delivered.Flex is a real find for small and midsize busi-

nesses that don’t have the time or expertise tobuy and implement these products separately.It features malware protection and content fil-tering, including antivirus, anti-spyware, behav-ior analysis, intrusion detection, antispam, emailfiltering, policy management, data leak preven-tion, bandwidth management, rules manage-ment, traffic monitoring, application control,and botnet protection—in a single package.

Even more important, users can implementthese capabilities in various ways, including asan on-premises appliance, software as a serv-ice, or a remote agent on mobile and homedevices. Customers can choose the level ofprotection they want to implement them-selves and outsource the rest to a third party. It’s all offered in an affordable pricing

scheme that starts at $1 per user. BarracudaFlex makes security available and affordableto every company, rather than just those withdeep pockets or great expertise. —Tim Wilson

Storage System Startup Doesn’tSkimp Where It CountsSmall to midsize storage systems havebeen popping up everywhere, but securityfor these easily “relocated” systems is oftenan afterthought, if it’s even considered at all.The winner in our startup category, Cipher-tex, may be one of the first SMB storage com-panies to take data security just as seriouslyas price, performance, and data protection.It’s always refreshing when com panies lookat the big picture in developing their prod-uct strategies.Ciphertex came to our attention through

one of its new storage systems, the CX-

Ranger-EX, a portable AES 256-bit hard-ware-based encrypted RAID system witheSATA, FireWire 800, USB 3.0, and USB 2.0connectivity, and as much as 15 TB of stor-age capacity. We couldn’t help but be im-pressed with the thought process that’s be-hind the products and services Ciphertex offers.The company’s top executives are an im-

pressive group of seasoned storage and se-curity pros, and that expertise shows in thedesign of the company’s product matrix.Security and portability don’t come at apremium, either, in Ciphertex storage hard-ware. A quick review of the company’s

products shows a number of reasonablypriced devices and security-based servicesthat deserve further examination.Services listed on Ciphertex’s website

could be directed at any number of verticalindustries that require detailed data securityor forensic data services. However, the com-pany’s secure storage devices are pricedcomparably or even better than other sys-tems that don’t offer security options. It’slikely that Ciphertex portable storage prod-ucts would be a good fit for practically anysmall to medium storage application re-gardless of whether security is a priority.

Survive The Big OneWhat would you do if every single adult inthe United States decided to load your web-site at the same time? Seriously, do you thinkit would survive the onslaught or simply foldlike a grocery bag? Many businesses will never need to find out,

but a growing number regularly deal with ex-tremely high levels of traffic, and they need toknow how resilient they really are before anunforeseen event does it for them. Breaking-Point Systems’ FireStorm Cyber TomographyMachine—the winner in the Best Of Interopnetwork management, monitoring, and test-ing category—may be just what those com-panies need.Companies that run really big systems re-

quire really big testing tools—and brother,the FireStorm CTM is just that. Capable ofemulating 90 million users simultaneously, afully equipped FireStorm chassis takes uponly three rack units of space. Yet it can, andwill, stress your environment right to thebreaking point.The people at BreakingPointSystems take great pride in helping compa-nies find out just when and how their sys-tems will fail, so they don’t have to find outthe hard way.The modular chassis of a FireStorm CTM

starts with a FireStorm control module andsupports up to three four-port, 10-Gbps Eth-ernet modules, bringing its total bandwidthto 120 Gbps of combined throughput. Evenmore impressive, FireStorm CTM doesn’t justfocus on raw infrastructure throughput; it’salso a detailed testing system that provideshighly accurate model-ing templates for 150common, application-specific protocols as wellas more than 4,500 typesof security exploits rightout of the box.What we really like

about the FireStorm isthe simplicity it brings tothe complex science of production model-ing. If you’ve done any performance testing,you know that the most challenging part isdesigning a load matrix that’s even close tothat of a real production environment. TheFireStorm comes preloaded with a largenumber of preconfigured testing templatesyou can easily set up to mirror a variety ofproduction scenarios. From there, you can in-sert any number of potential security threatsto further emulate real-world conditions andgenerate granular reports with the precise

visibility of its 10-nanosecond resolution.Another impressive aspect of this testing

brute is the BreakingPoint Resiliency ScoreLab. This is a simplified, wizard-driven testingoption that lets even nonexpert users initiatea highly detailed test suite that generates averifiable, repeatable, and easy-to-understand

Data Center Resil i ency Score. It’s this combination of

power, sim plicity,flexibility, and turn -key functionalitythat makes Break-ingPoint Systems’Fire Storm Cyber To-mography Machinea worthy Best Of In-terop winner.

But don’t let the six-figure price tag put youoff. When you try to calculate the cost of allthe servers, applications, and networkingtools (not to mention test development time)necessary to come even close to the capabil-ities of a single FireStorm, it starts to look likean amazing bargain. And whatever you do,don’t run it on a system in production!
