The Wireless Office: Don’t Believe the Hype

Michael Morisy Michael Morisy Profile: Michael Morisy

While it might make me a public enemy in some circles, I have to stand by my assertion that we haven’t truly hit the age of the wireless office … yet. Josh Stephens, head geek blogger for SolarWinds, vehemently disagrees however, arguing it’s time to cut the cord.

He makes some decent points about wired vs. wireless security, although I’d argue that while .11n brings some marginal security improvements, it really ramps up the security complexity and opportunity for misconfiguration, which even he fingers as the culprit in Ethernet security lapses.

Where Josh really goes off the rail, however, is cost:

Next let’s debunk my buddy Michael’s point about cost. With 802.11n you can run 30-40 users per radio which means fewer expensive cable runs and fewer wireless switches. Combine that with mesh technology and you may not even need to run cable to all of the APs. This cost calculator from Aruba Wireless shows some great examples of how much you save. Mike, buddy, have you priced the costs of having an office wired with cat-6 lately? Even if you go all redneck, like I’m known to do, and run, terminate, and patch the cabling yourself it’s still incredibly expensive. In what universe is this not signicantly cheaper than a wired environment?

This is where he swallows the wireless vendors’ bait hook, line and sinker. A calculator, put out by a wireless vendor, shows that their products are cheaper than a competitive technology? Shocker! The problem is that, once you dive into the real numbers, you’re not going to stick 30 to 40 users on an AP, as Josh suggests. Sure, you could, and you could also use .11n to blanket a huge range, and provide throughput of 200 MBits/second, but it can’t do all those things as once, which a lot of calculators conveniently forget.

Another fact they conveniently forget: Even with .11n now an official standard, compatibility between sanctioned .11n devices is very imperfect when you’re talking about enterprise equipment. This means that no, you’re probably not going to save on all those pricey wiring costs because something, somewhere will need Ethernet.

But don’t take it from me: I tracked down Osaka Gas, hailed in 2007 by ComputerWorld’s Matt Hamblen as the largest “all-wireless” office, to get an update on what they’d learned and accomplished since becoming a poster child for cutting the cord.

There were some surprises:

1. This case study for the all-wireless office wasn’t then, and isn’t now, “all-wireless”!

Osaka Gas’ Toyoshi Matsumoto wrote to me:

We are using WAN for phones and PCs. Is that your definition of 100%? In fact we have NOT removed all LAN cables. Some fixed IP phones,  mainly used for receiving calls from customers or business partners are wired because the calls should be answered as the company not as an employee. Desktop PCs are also wired because they do not need mobility. Another use of wired LAN is the emergency use when WLAN gets unstable.

Three years as an all-wireless office, and a) It still makes more sense for some tethered IP phones b) Desktops are still wired and c) their WLAN still becomes unstable!

2. Toyoshi goes further, and says forget saving money simply by cutting the chord:

It’s not necessarily appropriate to suggest that wireless itself contributes to cost saving or improving efficiency. In many cases of  introducing wireless LAN as a replacement of wired LAN, you cannot expect cost savings.

Corner any wireless vendor for long enough on the cost savings issue, and they’ll invariably agree with this assessment. Sure, they have those nifty calculators Josh likes, but when you actually start computing the real totals, you’re maybe breaking even, but just as likely paying more for the Wi-Fi privilege.

3. Compatibility problems persist. Toyoshi puts a gentle spin on this one:

We have been using Meru since the project started. We have also other products from vendors such as Cisco, Aluba (sic), etc., to identify similarities and differences among them to determine their compatibility to our environment, because wireless technologies and standards continue to advance.

But the fact is, any major wireless deployment that’s dealing with more than students and their iPods has found the same compatibility issues. How often do you run into an Ethernet cord that isn’t compatibility with your laptop, projector, or other device (except those devices, naturally, that don’t have a port).

In the end, wireless is a great tool but it’s not the panacea that the industry makes it out to be. As Toyoshi put it, “‘Wireless’ is a means, but not a destination.” Don’t believe the hype otherwise.

Checking back with 2006’s largest “all-wireless” office.

Michael Morisy Michael Morisy Profile: Michael Morisy

Editor’s Note: Below is the e-mail exchange between me and  Toyoshi Matsumoto of Osaka Gas Co., which was hailed almost four years ago as the largest all-wireless office. For background, see here. I reproduce the exchange below unedited. -Michael Morisy

1) How did the wireless experiment in 2006 go?

It went very well.  The project proceeded as originally scheduled and we achieved the 50% cost saving and improved efficiency as projected.

2) Did you continue on with Meru in this project?

We have been using Meru since the project started. We have also other products from vendors such as Cisco, Aluba (sic), etc., to identify similarities and differences among them to determine their compatibility to our environment, because wireless technologies and standards continue to advance.

3) Is this office now 100% wireless, or was it just deskphones that were wireless?

We are using WAN for phones and PCs. Is that your definition of 100%? In fact we have NOT removed all LAN cables. Some fixed IP phones,  mainly used for receiving calls from customers or business partners are wired because the calls should be answered as the company not as an employee. Desktop PCs are also wired because they do not need mobility. Another use of wired LAN is the emergency use when WLAN gets unstable.

4) Have you upgraded to .11n, and have you run into any challenges with that?

Not yet, but as stated above, we are trying various products and will try .11n in the near future because we are planning to replace the current wireless system in 2011 that is our Meru products’ economical end-of-life.

5) If you’ve moved to 100% wireless, why did you and what benefits did you see in terms of cost savings or efficiency?

6) If you’re not, what was behind the decision not to go 100% wireless?

It’s not necessarily appropriate to suggest that wireless itself contributes to cost saving or improving efficiency. In many cases of  introducing wireless LAN as a replacement of wired LAN, you cannot expect cost savings.

Our project started from the replacement of conventional PBXs. PBXs were so expensive that we could achieved 50% reduction of facility cost in terms of depreciation cost.

In terms of efficiency improvement, we not only introduced wireless LAN but also promoted to change our workstyle from paper-based one to full-digital one. Wireless environment and full-digital workstyle allow us to access, transmit and share real-time information anywhere, which leads to efficiency improvement.

7) Any other advice for companies considering going all wireless?

We believe that the use of wired and wireless systems and 3G and VoIP phones in optimal combinations is important for us to improve our work efficiency and thereby reducing operation costs.

“Wireless” is a means, but not a destination.

Time to start picking sides in the mobility wars

Michael Morisy Michael Morisy Profile: Michael Morisy

While the tech world has been hyperventilating about the patent tiff  between HTC plus Google against Apple, a more serious war has been brewing in IT departments for years: How do you build a reasonable strategy based upon shifting standards and where future market share is nearly impossible to accurately predict? Just a few years ago, IT departments were scrambling to adopt policies for the iPhone. Now, it’s the Droid. And possibly the Pre. And the Nexus One.

Remember the good old days when everything was BlackBerry, except for some Windows Mobile thrown in for your industrial-strength computing needs? Now even WinMo is getting all spiffy, with Windows 7 making its mobile debut this Winter on a phone that doesn’t even include windowing.

So how are you picking sides in the mobile wars? Do you let your users pick their own phone, have a list of supported devices, or simply parcel out devices from on high? I’d love to hear your thoughts about what problems you’re struggling with, simply post any thoughts in the comments or e-mail me at Michael@ITKnowledgeExchange.com.-

Don’t cut the cord yet: The truly wireless office is years away

Michael Morisy Michael Morisy Profile: Michael Morisy

I recently wrote about the paperless office and the post-e-mail era, two arguably worthwhile goals that share the fact that they’re nowhere close to reality except in a few small quirky progressive shops. The next myth I’d like to tackle is the wireless office: The dream of workers everywhere, but one we’ll have to wait on a bit before truly waking up to it.

The benefits of this supposed wireless wonderland, fueled by .11n and powered by pixie dust, is ease, accessibility and even cost savings. Imagine, users can just pony up to any office corral they want, pop onto the Wi-Fi, and even re-group with different colleagues with ease. No need to send an IT tech to reconfigure or troubleshoot their Ethernet jack, they just hop onto the same wireless connection no matter where they are. Those IT calls add up, and there’s a is a real cost. Several IT professionals estimated that each desk move runs a couple hundred dollars just in the time it takes to set the user up for access to the Internet and corporate network.

And the dream is nothing new: A few weeks after I started working at SearchNetworking.com in 2007, I was getting pitches about it. A quick search through my e-mail turned up tens of thousands of e-mails for “all wireless office,” from PR flacks, newsletters and mailing lists.

And flacks still tell me regularly: This is the time for the all-wireless office.

But the reality is, just like the paperless office and the e-mail-less office, we’ve got a long hard road ahead.

Take one of the top Google results for the topic, Matt Hamblen’s “All-wireless office launches for 6,000 users at Japanese company“.

Of course, once Matt dove into the details, he found that the office wasn’t really all wireless: A lot of workers still had traditional deskphones, and even the 6,000 wireless phone users had backups in case of a power outage.

But Michael, I hear you argue, that was three years ago. .11n has finally been ratified! Sure, and it’s brought a host of improvements, but in interview after interview with networking professionals, I’ve found that wireless companies routinely over-promise, under-deliver and leave customer after customer holding the bag.

Here’s three areas that give me pause:

Consistency: .11’s MIMO is a whole new ballgame for wireless, and the improvements are great. But they’re also overstated, because just as the greatest maximum reach has been extended, so has its unpredictability. That better-than-broadband throughput only comes through if you’re lucky, unless …

Cost: There’s a reason wireless vendors are so happy to pitch the all-wireless network: You’ll end up saturating your offices with access points. Access points that are “cheap” if they come in under $600. Access points that will have to be super-saturated once you discover that you have users clustering around in a meeting room. So much for saving on those desk moves.

Commodity: When you buy Ethernet cables, you pretty much buy Ethernet cables. And they’re a dirt chip commodity at this point. Forget that when it comes to wireless: You’ll have to pick a vendor and stick with them for a long, long time, bending over every upgrade cycle for whatever specific product they have to fit your need. And you’ll have to get the whole matching kit and caboodle, too: The controllers, the APs, the security consoles, the software that does your coverage mapping which, by the shows, shows you need even more of those proprietary controllers and APs.

I won’t argue that there’s not a lot of benefit that the ratified 802.11n standard brings, but be careful that your enterprise doesn’t get caught up in the spin.

If you’d like to read more, I highly recommend Lisa Phifer’s three-part series on .11n (registration maybe required), which advocates and explains a mixed network methodology, a compromise that, just like reduced paper offices, makes a lot of sense.

There is no Knight in Shining Armor in Cloud Computing

Michael Morisy Guest Author Profile: Guest Author

Editor’s Note: This guest post is from Ed Laczynski, founder and CTO of LTech. -MM

I talk to a dozen or so IT managers, CIO’s, and decision makers every week.  My sales and business development staff speaks to another hundred or so.  Looking back at the past year of business in cloud computing, we’ve come up with an anecdotal trend.  IT management falls into two camps: pioneers and damsels in distress.

“Pioneers” are ready, willing, and able to take the plunge into cloud computing. They know that their job function might change, their users may go through some unrest, and their management will be tentative.  However, they also know that the world is changing.  The disruptive cost savings, productivity, and functionality that cloud computing provides is not worth fighting against; instead embracing it with the right mind towards managing, integrating, and operating the technology is the correct course of action.  The pioneers we worked with in the early parts of 2009 are already seeing the benefits.  Pride in ownership of successful deployments, savings of hundreds of thousands, if not millions of dollars, and control of their own destiny in this new era of technology give the pioneers the confidence to continue the adoption cycle of cloud.

However, “Damsels in distress” aren’t so happy about all this cloud hullaballoo.  They say cloud is really all about private datacenters.  Or, it’s all about some new product coming out soon from your typically enterprise software company, that promises to be a knight in shining armor – allowing them to keep the status quo and innovate at the same time.  These IT folks are content with managing hundreds of servers, in costly real-estate, with even costlier software licensing.   When opportunities to move to cloud computing come knocking, they yell “Get off my lawn!” and hug their servers and enterprise software licenses that surely keep them warm at night.

But business is changing.  It is about interconnectedness, collaboration, and scalability.  The very things the Internet was born from.   The companies that were built on the Internet – like Google, Amazon, and Salesforce, have built the framework for IT and it’s ready.

We are moving from an era when your typical desk worker received 30 emails per day, to one where hundreds would be considered a quiet day.   The tools of yesteryear – Notes, Exchange, Outlook, aren’t going to solve the problems of information overload that companies are being saddled with.  Massively multi-tenant systems like Amazon Web Services and Google Apps have stellar uptimes and reliability when compared with on-premise or pretend cloud solutions like Microsoft BPOS, which has had enough outages to scare away only the most dyed-in-the-wool Microsoft fan.   None of this is lost on sales and marketing departments, who want to innovate and keep a leg up and not be told they have to wait weeks for procurement of licenses and servers to stand up technology to win market share.

The knight in shining armor won’t show up because he doesn’t exist.  The last thing companies like Microsoft can do is cannibalize their on-premise server and productivity business with cheap, effective, cloud alternatives.  Even if they were willing to do it, can they really deploy the data center and scaling capabilities that their Internet-born competitors already have a decade jump start on?

The Pioneer is going to look at an IT problem, like standing up a development environment, or deploying world-class CRM, and laugh at its simplicity and cost.  The damsel in distress will wait for Topaz Cloud Connection and Scalability Server 2011 Plus, Enterprise Edition (for Servers) while the competition spends more money on sales and innovation than keeping those servers warm.  If you think the companies of yesterday are going to chew their own arms off to deliver you highly scalable, internet powered, cheap cloud computing, you’ll be waiting a very long time.  So think hard about what technologies and IT providers you want to cast your lot with in 2010.

The company (www.ltech.com) provides products and services that connect business to the cloud. LTech has successfully completed hundreds of cloud deployments and our cloud enablement products are being used by hundreds of thousands of users worldwide.

A-Commerce: 10 Ways APIs will change IT Operations

Michael Morisy Guest Author Profile: Guest Author

Editor’s Note: Today’s guest post is by Sam Ramji, vice president of Sonoa Systems and former head of open source strategy for Microsoft. If you liked what you read, he has his own blog or you can follow him on Twitter. -MM

You’ve probably heard that Twitter’s API has been the primary driver for the fast growth and rapid morphing of Twitter’s service.  You may know that eBay and Salesforce.com get over 60% of their usage via APIs.  And in the last couple of months, you may have heard people at your company in marketing, business development, or software engineering talking about your own API.  If not, you will soon.

If you’re in the retail industry, this is going to make you very busy for the next few years.  APIs are a technology buzzword that basically equate to a new way to use the web.  In the 90s every retailer went “online” to take advantage of the cost of sales and margin improvements that came from having an e-commerce channel.  These sites enabled companies to “sell direct to millions of new customers”, and those who got online later had to race to catch up just to protect their businesses.

Now in the 2010’s there’s a new way to use the web – a-commerce, or commerce via APIs.  Mobile app and web app developers can use APIs to build very cool new applications that look and behave totally unlike your core website, but use your commerce engine just like a regular affiliate.  This lets them get to consumers who would never have come to your website, but love to use the app and therefore your company makes money.

While at first this may sound like nothing new, it turns out that there are a lot of new issues to manage.
The 10 New Factors of A-Commerce for IT Operations

1. Performance: API-driven demand patterns & load on infrastructure are really different from web-driven demand.  Developers will often wrap a database object directly in an API rather than shielding it with a web page that limits the number of rows that will be returned; programs will use that API in unpredictable ways that will load your system differently.  Added to that, many more new concurrent connections from thousands of new sources will be simultaneously hitting your backend servers.

2. Analytics: Channel sprawl is a good thing for margin, but tough on reporting.  There are multiple channels that affiliates are coming through – iPhone apps, tablets, web apps – and you’ll need to provide a combined view on their activity.  API traffic cannot be seen by Google Analytics or any existing web tool so you will need to figure this out.

3. Auditing: Recording the sources of the a-commerce transactions and integrating with affiliate management services to pay a-commerce partners is important.  Payment disputes will happen and you need to have a trail of data to show what happened in your systems.

4. Seasonality: Preparing for holiday rush is critical in order to run a trustworthy a-commerce service.  This requires not just performance forecasting and knowing what can be cached, but how to throttle low-value requests when high-value purchases are in the queue.

5. Security: The number of usernames and passwords are going to explode.  Don’t make users and developers build a new username and password to use your system.  By making OAuth the standard you can let users and developers log in using their Twitter or Facebook accounts.  This will save you a ton of hassle managing password resets and angry users.

6. Protection: Prioritizing traffic between web visitors and API users – who has priority when your infrastructure is under load?  Additionally, protecting against a-commerce threats requires filtering out XML header bombs, SQL injection attacks that come in via the API, and other new forms of attack.

7. Privacy: Ensuring that sensitive data isn’t exposed incorrectly requires knowing and controlling what customer and commerce data is leaving the firewall, staying in compliance, and ensuring PCI standards are met.  In an API world, this data is hidden in XML and JSON formats which you will need to scan and manage.

8. Evolution: Unlike a website which is under your control, or under the terms of “caveat emptor” when you are being webscraped, now there are affiliates who are depending on the API working a certain way.  When the development team changes their code and builds a new version of the API, you need to be prepared to manage apps that break.

9. Provability: SLAs multiply in this scenario.  Make sure that you can prove that your service was up and responding when upper management comes looking for who to blame when things go wrong for a high-priority a-commerce affiliate.

10. Debugging: this used to be something that just the internal development team handled by themselves; you may or may not have been involved.  Now there are a ton of new developers trying to figure out how to use your service, sending malformed requests, generating errors.

The specific combination of analytics, debugging, provability, and protection will come in extremely handy during the winter holiday season – being able to understand traffic spikes, identify misuse of your platform and removing that traffic while letting the good transactions continue to flow will be crucial in preventing downtime and maximizing revenue generating CPU cycles.

In the next articles in this series, we’ll dive deeper into each of the 10 issues listed above.  Let us know which ones you’re most interested in and we’ll cover those first!

Former SalesForce CEO: The Cloud is Coming

Michael Morisy Michael Morisy Profile: Michael Morisy

SalesForce.com has been the darling of the enterprise SaaS industry, with explosive growth that has eaten away at traditional CRM vendors’ marketshare. The company’s now poised, with Force.com, to extend its dominance even farther, but former CEO Steve Cakebread says that the cloud arena is just starting to get interesting.

He said that since leaving SalesForce.com, he’s been consulting with eHealth companies, portfolio managers and Xactly, a SaaS-based sales compensation company, where he is now the chief financial and administrative officer.

Almost all of those conversations focus on one topic: The cloud will change the future of enterprise IT.

“My long-term view of the [SaaS] industry is that over the next to 10-15 years, it replaces on-premise software completely,” Cakebread said in a recent interview with the IT Watch Blog. “There’s a lot that needs to come out before then, but I’m pretty convinced today that with the architectures being put in place that nothing needs to be run on premise.”

According to Cakebread, it just makes too much sense: “Every CIO is worried about redundancy and disaster recovery. if you’re using a couple different SaaS providers, that’s something you don’t have to worry about.”

Make sure they have a solid, distributed network of data centers, and CIOs can sleep a little easier knowing that even if a cable is cut by a careless backhoe or a data center burns down, their data is safe and accessible somewhere, somehow.

Of course, with cloud computing, one chief concern (just read the ITKE forums) is security. Denny Cherry captured a prevalent feeling when he wrote that, ” If you need to be sure that your data is secure, then a Cloud platform may not be the correct choice.”

Cakebread disagrees, however, saying that more cloud vendors are becoming open about their security practices and willing to work with companies.

“The larger companies allow your IT security people to come in and look at the setup, and they come away feeling comfortable the security was as good or greater than what they have internally,” he said. The same goes with uptimee. He had the same message on uptime, performance and interoperability: No, the cloud may not be perfect, and you’ll have downtime when your Internet is down, but the uptime and reliability is still, in many cases, better than what companies are getting today so why not go with cloud?

He also said that there’s one area ripe for SaaS conquest: ERP. While there are some players in the field, like NetSuite, it’s a hugely complicated problem because of the integration, security, and uptime required. That complexity means it’s also a huge potential win for whoever can master it first and seize marketshare.

“Right now, everyone builds their tools around their core ERP,” Cakebread said. “There are vendors there, but they need to make their applications worldclass and robust.”

Are you prepping for the post-E-mail era?

Michael Morisy Michael Morisy Profile: Michael Morisy

“You may say that I’m a dreamer, but I’m not the only one.” – Imagine, by John Lennon

It’s not uncommon for office workers to pine for the days before e-mail everywhere, particularly those workers tethered to the office 24/7 by the BlackBerry and its incessant e-mail chirps, buzzes or beeps. But maybe they can now start taking heart from the promise of a post-e-mail era.

Who else is dreaming with them? Well, Microsoft’s Outlook team for one. Microsoft’s Social Connector doesn’t quite put social networking on an even level with e-mail, but it’s getting pretty close: It crawls your social networks and even internal tools to present context relevant data right in Outlook, which for millions literally defines what e-mail is.

I use the term “post-e-mail” loosely and, even then, hesitatingly. For years, we’ve been promised the “post-paper” office, only to find that the proliferation of computers actually increased paper usage. But the importance of paper files certainly has decreased over the years, and by throwing social networking into it’s main communications mix, Microsoft is likely signaling that e-mail is likely taking the same path. In other words, your e-mail cup will still runneth well over, but you’ll have a wider selection at the bar to choose from.

Playing project management poker

Michael Morisy Michael Morisy Profile: Michael Morisy

Project management is incredibly simple until you actually have to do it, which is why books, seminars and other aids abound. I’d heard of T-Shirt Sizing before, where team members are asked to help estimate and prioritize project elements using relative measures, rather than guessing the absolute time or manpower needed. Yvette Francino uncovered another project estimation technique, Project management poker:

Planning Poker is a technique where each team member use cards with a range of numbers to estimate effort. Typically the numbers do not progress incrementally, but are more spread apart, the higher they get. The Fibonacci series (0, 1, 2, 3, 5, 8, 13, 21, …) can be used for this. The reasoning behind this is that the larger the numbers get, the more uncertainty there is.  Cohn gave us each a deck of cards and had us do an exercise in which we were given several tasks and then work in teams to estimate those tasks using the cards. If we didn’t agree on the first pass, we would explain our reasoning and vote again. In all cases, we were able to reach consensus quickly.  Cohn even has made a free planning poker tool available for distributed agile teams.

Yvette has posted some videos that more fully explain why poker planning works, and there’s even a free tool to try it with your team online. While that tool is specific for Agile development teams, I would love to hear if you think, or any other project estimation techniques, are useful in your department when plotting out major projects.
