More technologies that won’t be ignored, according to Gartner


Virtualization, cloud computing and social software are among the buzzier terms, but Gartner says storage, green technology, complex resource tracking and more will be top of mind in the coming months for high-tech leaders.

By Denise Dubie

IT executives could be buried in data, struggling to track resources and looking for ways to go green in the coming years, according to research firm Gartner, which advises high-tech leaders to pay attention to these technologies today.

Technologies that won’t be ignored

While virtualization, cloud computing and social software make it difficult for IT professionals to ignore them, other less hyped technologies could fall off the radar. Gartner recently hosted a Webinar, Technology Trends You Can’t Afford to Ignore, in which Managing Vice President Raymond Paquet detailed 10 technology trends that IT shouldn’t ignore.

To start, IT leaders can expect what Gartner dubbed a “data deluge.” Paquet said on the call that enterprise data growth is expected to growth 650% in the next five years, and that 80% of that data will be unstructured. That means what is budgeted for storage today is insufficient, according to Paquet.

Energy and green technologies should also be taking a higher priority for IT leaders. “We need to start developing metrics that force us to review the efficiency of IT,” he said. “And it causes us to work with facilities.”

Apple supports enterprise apps on iPhone - Insert your own iPun here.


June 16, 2007, Network World:

"We're telling IT executives to not support it because Apple has no intentions of supporting (iPhone use in) the enterprise," Gartner analyst Ken Dulaney says. "This is basically a cellular iPod with some other capabilities and it's important that it be recognized as such."

March 6, 2008, Network World:

During a media conference at its San Francisco headquarters today, Apple unwrapped a host of new features that are designed to make the iPhone more attractive to corporate users.

Six months is a long time in the tech world…

We've warned that eventually the iPhone would be appearing on corporate networks and that the new (at that time) devices would introduce vulnerabilities into the corporate network and take additional resources. What we weren't counting on was Apple making overtures to enterprise networking - we had assumed that, much like the original iPhone was hacked to run on multiple carriers, that those who wanted to use the iPhone for enterprise applications would have to provide their own, messy, stop-gap solutions.

Back in January of 2007, when the iPhone was first announced, we wrote:

"That's another question - will this device have VPN support so that traveling employees can get the information they need while on the road? And if they do - how do you secure the data? The iPhone, like all small devices, is easy to lose, and easy to steal. That makes it vulnerable to illicit access. Does the iPhone have cryptographic abilities to make sure data stays safe?"

Well, apparently, Apple didn't take that as a rhetorical question because the fruit-based tech company is going to support Cisco IPsec VPN in the next iPhone update - the same one that will bring secure Exchange support as well as the possibility of an "iTunes Store for iPhone apps" - current Apple plans are to allow third party development but that Apple would have the final say on whether or not the applications could run on the iPhone. (Of course, clever hackers have already found a way around that.)

At any rate, the iPhone now seems to be competing directly with the Blackberry, which is good in the sense that competition in technical markets lead to innovation, and companies will have to expect new types of devices using different types of traffic, which - well, isn't bad, but which can be frustrating, absent a network device monitor.

Personally, I'm a bit confused by Apple's insistence to cripple the iPhone into only running "acceptable" applications on the iPhone, as A) it's clear that people are going to use it the way they like anyway, and B) if Apple took the same attitudes with their Macintosh/OSX general purpose computers, some of the best Mac apps (Quicksilver, Colloquy, Transmission, Burn,) simply wouldn't exist. Perhaps this increases the security of the device but at the obvious cost of utility.

It's just rhetorical, and I'd love to get some comments on this, but is the tradeoff between security and utility a false one? I'm not sure - havening not worked much in the security side of technology - but it seems to me that if the iPhone can be hacked to make it more useful, it can also be hacked to make it malicious, and so the choice is not between security and utility, but rather between a lack of security with utility, or a lack of security without utility. Hmm… maybe I should ponder this more.

I, Phone: Could the Apple iPhone's broad consumer appeal present a formidable threat to enterprise networks?


brianboyko.jpgBy Brian Boyko

In an early Network Performance Daily post, we spoke a bit about the impact that the Apple iPhone is likely to have on the company's IT department, and we thought that with some of the announcements of WWDC, it would be worth taking a look back and revisiting some of those ideas.

Back in January, we opined:

  • People will use the iPhone at their jobs the way they use Blackberrys now.
  • To the end-user, the iPhone is a personal cellphone, with no more need of IT scrutiny then their current phones. To the IT department, the iPhone is a mobile computer, increasing the complexity of the network and creating an additional demand of resources.
  • The iPhone's rumored "phone over WiFi" capabilities means that even if you don't intend to roll out VoIP, you may still be dealing with converged traffic on your network.
  • The iPhone's web browsing capability may draw additional bandwidth.
  • The iPhone would be used as a gateway to SaaS software such as Google Docs and Salesforce.com.
  • The iPhone is small enough to steal, requiring data to be secured.

Now that we know a little bit more about it, we can start to revise some of our predictions of how the IT department will have to deal with the new iPhone.

Why Apple's iPhone means more work for the IT department


brianboyko.jpgBy Brian Boyko

"Jesus has come back, and he's a phone now."

The Apple iPhone might not be the second coming, but it will certainly be popular. Already the Web is being inundated by speculation, information, mis-information, rumor, innuendo, and anyone with an opinion on Apple writing about the iPhone.

So we thought: Why buck the trend?

The truth is that when this device comes out, many people are going to buy the iPhone, they will use it at their jobs - including those in a corporate IT environment - and that means it is going to become the responsibility of the IT manager.

PERFORMANCE TOOLBOX: NetStumbler
As WiFi continues to turn up in unusual ways (such as IBM's/Xing's Kyoku-NAVI wireless karaoke machines) locating these devices becomes increasingly necessary. From the system administrator perspective, there may be a rogue 802.11 device operating outside of administrative policy; from the adventurous spirit viewpoint, there may be an opportunity to observe and perhaps utilize 802.11 bandwidth on an access point that remains unsecured. Spotting them for either agenda requires nothing more than an 802.11 adapter and the relevant configuration program, but you will glean only so much viable information using standard issue desktop applications contained on companion driver and installation disks. You can stumble your way through the wireless bubble and determine more usable information with NetStumbler.

TECHNOLOGY BRIEF: WLAN Performance
[WLAN connections] are prone to interference and attenuation (degradation of signal) from building materials and other electronic devices that may use similar frequencies (such as cordless phones, Bluetooth devices, or microwaves). The further away a wireless user gets from a wireless access point (WAP), the more likely they are to be affected by attenuation and interference. But unlike a radio station’s audible signal, data that gets lost on a wireless network typically must be retransmitted, if only because most networked applications use Transmission Control Protocol (TCP) for transport. Retransmission of lost data also impacts performance, and reduces overall throughput for user application(s).
