IT Departments Gone in 5 Years

IT Departments Gone in 5 YearsIT departments will be done in the enterprise within the next five years according to a group of CEOs and VPs. They predict that consumerization of IT and self-service trends will lead to a restructuring of today’s IT shop, leaving behind a hybrid model consisting of tech consultants and integrators. Brandon Porco, chief technologist & solutions architect at Northrop Grumman recently told a group at the CITE Conference and Expo.

The business itself will be the IT department. [Technologists] will simply be the enabler

IT Departments are targetsComputerworld reports that Kathleen Schaub, VP of research firm IDCs CMO Advisory Practice, echoed Mr. Porco. She said many corporate IT organizations now report to the head of the business unit it is assigned to. “The premise is that wherever IT sits in an organization will dictate what they care about,” she said. “If they’re in finance, they’ll care about cost-cutting. If they’re in operations, they’ll care about process management. If [the company] decides it wants to focus on the customer, they’ll put it in marketing.

John Mancini, CEO of the Association for Information and Image Management (AIIM), agreed with Mr. Porco, saying that in the consumer technology era, it’s the business side that has all the tools, so it will be able to trump IT’s desire to control who uses what and how.

functional business spending will outpace IT's spending.While the business can dictate the service or technology it wants, IT can influence the decision. Nathan McBride, VP of IT & chief cloud architect at AMAG Pharmaceuticals told Computerworld, “We’re not trying to be ahead of the technology curve and we don’t’ want to be behind, but we’re trying to maintain pace to know what they’re going to ask for next before they ask for it.

Help Net Security points out a recent IDC study that found 61% of enterprise technology projects are now funded by the business and not the IT department. IDC says IT spending driven by the functional business areas will outpace IT’s own spending. Today’s business executives who are more tech-savvy, have easier access to technology through the Cloud, and are under pressure to quickly implement new technology initiatives are driving this change.  The Help Net Security article states that today’s line of business employees are looking more and more like an extension of the IT department as, on average, 8% are technical staff.

Center of the universeAnother concern raised is whether IT is losing control as consumer technology becomes part and parcel of everyone’s work in the enterprise, and the data center is left behind. AMAG’s McBride told the audience, that in five years, companies will have to make sure they’re matching their enabling technology to the demographic of that time. He said 75 Fortune 100 companies now use Google (GOOG) Apps along with most Ivy League schools, meaning that the next generation of workers won’t be users of Microsoft (MSFT) Exchange or Office.

While the CIO position will likely stay in an enterprise, his or her role will morph into a technology forecaster and strategist, and not a technology implementer, according to Northrop Grumman’s Porco.

This sounds like a solid case for training technical staff in project principles and increasing the number of IT project managers. There have to be clear two-way communications between the business owner and the implementers.

Requirments ?Proper and detailed scope definition is one of the most critical steps for the success of any project. The business team, implementation team, and operations team must get together before the work starts to check the proposed solution and work through all the questions, concerns, and gotchas before the project even starts. This way problems can be discovered. Once the requirements are defined and the scope is complete and everyone agrees, then the project can be signed off and a formal kick-off meeting can be held.

In IT projects, it is important to look beyond the defined project to ensure success. Does the plan consider impacts on end-users?

  • Does the project need new policies or procedures? If something falls through the cracks, they blame your project.
  • Does the PC fleet meet requirements? Do they need more RAM? If they have to upgrade, they blame your project.
  • Does it work with your current server OS? If they have to upgrade, they blame your project.
  • What about the software? Are you locked into IE only? Do you need a specific level of .NET? Does it work on iOS and Android? If they don’t have the right software, they blame your project.
  • How much bandwidth does the new project require? Will it try to send a graphical interface to a remote office on a slow link? If it loads slow they blame your project.
  • Training? If the end-users can work the program, they blame your project.

Farewell Steve Tour

Farewell Steve Tour MicrosoftThe Bach Seat Steve Ballmer farewell tour continues as rumors swirl about Ford (F) CEO Alan Mulally taking over at Microsoft. Or will Bill Gates returning ala Steve Jobs to save Redmond. Whatever the grand poobah’s at MSFT are thinking. They will probably never find another CEO like Steve.

Here is newly minted CEO Ballmer opening up the company’s 25th Anniversary in September 2000, doing what he calls a “monkey dance” and shouting “give it up for me!” When he finally calms down, barely able to speak between gasps of air, he manages to shout four words: “I .. Love … This … Company!

Whats a Petabit Network

Whats a Petabit NetworkSeems like it was a couple of months ago, we were excited about fiber optic cable that twisted light to carry data at 1.6 Tbps per strand. Now a Petabit network is the new benchmark. U.K. and Japanese researchers mashed up software-defined networking (SDN) and multicore fiber to produce the first Petabit pipe according to Kevin Fitchard at GigaOM. A Petabit is one quadrillion (1,000,000,000,000,000 or 1015) bytes binary digits or one thousand Terabits.

Petabit network uses multicore fibers

Whats a Petabit NetworkThe researchers mashed up multicore fibers and SDN to makes very high-speed networks programmable. GigaOM speculates this will allow carriers to adjust the network capacity and latency to meet the needs of traffic traveling over their networks. First, GigaOM explains that the fiber is unlike today’s single strands of glass, or cores, that carry a single beam of light down the fiber. Multicore fiber is exactly what its name implies: multiple cores each carrying a single core’s worth of capacity over the same link. Professor Dimitra Simeonidou at the University of Bristol called current single-core fiber a capacity bottleneck.

Space Division Multiplexed

The multicore group, led by NICT and NTT in Japan which built a 450 km (280 miles) section of fiber optics using 12 cores in two rings capable of transmitting 409 Tbps in either direction. That’s 818 Tbps in total. Which is within spitting distance of seemingly mythical Petabit speeds according to GigaOM. The MCF research relies on Space Division Multiplexed (SDM) provided by the multicore fibers.

ResearcherIn order to control the massive bandwidth, a team from the High Performance Networks Group at the University of Bristol created an OpenFlow software-based control element to manage those enormous capacities. The Brits implemented an interface that dynamically configures the network nodes so that it can more effectively deal with application-specific traffic requirements such as bandwidth and Quality of Transport.

According to the researchers, this was the first time SDN was used on a multicore network. The University of Bristol presser announcing the new technology says this technology will overcome critical capacity barriers, which threaten the evolution of the Internet.

OK, so that really – really – really fast. We also know from a 2011 New Scientist article that the total capacity of one of the world’s busiest routes, between New York and Washington DC, is only a few Terabits per second. With bandwidth-hungry applications like cloud computing, social media, and video-streaming continuously growing it forces network planners at firms like AT&T (T), Verizon (VZ), and the NSA to find new ways to grow their capacity.

Data center

Comcast (CMCSA) just finished a 1 Tbps network field trial on a production network between Ashburn, VA, and Charlotte, NC. Most likely the first place Pbps networking will be used is in the mega-data centers of the likes of Google (GOOG), Facebook (FB), or Microsoft (MSFT).

More Tech Trouble at School

More Tech Trouble at SchoolIt’s not a good time for tech in schools. The security woes at school are not limited to the iPad debacle at LAUSD. (rb- You can see my coverage here – Updates since the first article – LAUSD started confiscating the iPads and delayed the district-wide roll out one year until 2015.) GigaOM’s Ki Mae Heussner writes that Guilford County Schools in North Carolina has suspended its tablet program with Rupert Murdoch’s News Corp’s Amplify after reports of faulty equipment.

NC school district suspends tablet program

uspended its tablet programThe district reportedly spent $16.4 million ($299 / device + a 2-year subscription at $99 per year) of a $30 million Race to the Top grant to pay for the tablets and content. The device is a 10-inch ASUS (2357) tablet running the Google (GOOG) Jellybean Android operating system. It comes pre-loaded with content and apps curated by Amplify. It enables teachers to distribute content across a class or grade level and control the content on students’ screens.

GigaOM cites the school district’s website, which says they have sent 10% of their 15,000 devices back to Amplify because of broken screens. About 2,000 cases have also been problematic. In one instance, a student returned a defective charger, reporting that overheating caused the plastic to melt. While the district said it expected a few glitches with the rollout, school officials decided to pause the program for safety’s sake. GigaOM claims the pause is a big setback for Amplify, which launched its education-optimized tablet at hipster South by Southwest earlier this year.

NewsCorpSince its launch, skeptics have wondered how schools would respond to the privacy questions and the prospect of doing business with Amplify’s parent company News Corp. (given its phone-hacking scandal). Ms. Heussner speculates that the suspension could give schools more reason for pause when it comes to embracing the new technology.

Asus told GigaOM that out of 500,000 chargers of its kind that they have shipped globally, only the one in Guilford overheated and melted. Justin Hamilton, Amplify’s SVP of corporate communications seems to be blaming the customer. He claimed the broken screen rate in Guilford is higher than in other school districts. “We’re working very closely with the district on this and hope to have things resolved and the program back up and running very soon,” Mr. Hamilton said.

Indiana mobile security fail

circumvented the security on district-issued Apple iPadsIn Indiana, Education Week reports that between 300 and 400 students in the Center Grove school district circumvented the security devices on district-issued Apple (AAPL) iPads within hours of receiving the devices according to a report last week in the Daily Journal.

Apparently, students found ways to reprogram the iPads so they could download games and apps for social media sites, according to the report. Center Grove officials attributed the problem to their security program not being able to handle the 2,000+ devices they distributed.

spread like wildfireKeith Krueger, the CEO for the Consortium for School Networking, said such problems are increasingly common as districts deploy an increasing number of devices. “Kids and adults find ways to hack through things, and it can spread like wildfire,” he said. “It’s frustrating, and it’s a huge challenge for any district.

Data center failures

In addition to the tablet troubles, Data Center Knowledge’s Rich Miller reports several school data center failures. According to DCK, two public school systems suffered data center failures that crippled their IT systems.

data center fire suppression systemIn Oregon, the Beaverton School District experienced several days of disruption after an errant alarm set off its data center fire suppression system. The fire suppression system damaged hard drives and servers. That left Beaverton schools unable to use email or access class lists, student schedules, and online textbooks. “It knocked all of the systems in the data center off-line,” said Steve Langford, chief technology officer. “All of the systems that staff needs to do their jobs.” District IT staff worked over the Labor Day weekend to replace the damaged systems.

In California, the Davis Unified School District started school without key IT services after the district’s servers overheated. DCK reports an air conditioner unit failed, allowing the temperature in the server room to rise to 120 degrees F. “There’s an incredible impact on everyone in the whole organization,” says the district’s Kim Wallace. “Students can’t access computers. Teachers can’t take attendance. Parents can’t email. We can’t email out.” The DCK article said staff were still troubleshooting damaged equipment and lost data.

The best strategy, COSN’s Krueger said, is to combine the best possible security filters and other technical measures with a comprehensive responsible or acceptable use policy that students and families must sign and a commitment to enforcement. “It’s not surprising that a school district would have some breaches,” he said. “The question is how do you leverage it into a teachable moment?”

Who needs the teachable moment? Sure the kids need to understand there are real consequences for their actions but, can the politicians administrators be taught to be serious about IT? Seems to me that most of these failures are management failures. It is probable that these failures could have been reduced with proper project management.

proper project managementIt is my experience that many administrators do not recognize project management professionals. It appears they would stick with the good ole boy network and hire their less qualified friends or the professional BSer’s.

Now about project management? Modern backup system? Disaster Recovery plan?  BCP?

A Close Look at 802.11ac Wi-Fi

TA Close Look at 802.11ac Wi-Fiech pundits argue that the new Wi-Fi standard 802.11ac will replace wired gigabit Ethernet networking. 802.11ac is a supercharged version of 802.11n, offering link speeds ranging from 433 Mbps, up to multiple gigabits per second.

Wi-FiTo make 802.11ac dozens of times faster than 802.11n, the new standard works exclusively in the 5GHz band uses a huge chunk of bandwidth (80 or 160MHz), operates in up to eight spatial streams (MIMO), and a technology called beamforming.

At its core, 802.11ac is essentially an updated version of 802.11n, according to Sebastian Anthony the author of an ExtremeTech article “What is 802.11ac WiFi, and how much faster than 802.11n is it?” 802.11n was a huge performance increase over 802.11a and g. 802.11n introduced some key technologies that brought massive speed boosts. Where 802.11n had support for four spatial streams (4×4 MIMO) and a channel width of 40MHz, 802.11ac can use eight spatial streams and has channels up to 80MHz wide, which can be combined to make 160MHz channels. This means that 802.11ac has 8 x 160MHz of spectral bandwidth to play with, versus 4 x 40MHz – a huge difference that allows 802.11ac to send vast amounts of data across the airwaves.

Beamforming

What is new in Wi-Fi

802.11ac also introduces 256-QAM modulation (up from 64-QAM in 802.11n), which sends 256 different signals over the same frequency by shifting each signal to a slightly different phase. In theory, this quadruples the spectral efficiency of 802.11ac over 802.11n. Spectral efficiency is a measure of how well a given wireless protocol/modulation/multiplexing technique uses the bandwidth available to it.

802.11ac also introduces standardized beamforming Matthew Gast, Director of Product Management at AeroHive Networks published an article, “Investing in Beamforming: Is it worth it?” that explains beamforming.

Aerohive logoRather than transmitting a radio signal in all directions, beamforming figures out where the receiver is, and focus the energy towards the receiver. Instead of spraying radio energy all over the place, send packets as a “rifle shot” directly to the receiver’s antenna Mr.Gast explains.

Beamforming is a two-step process: First, figure out how to “aim” the transmission at the receiver, and second, send the transmission. With beamforming, a transmitter is betting that by paying the cost of the channel measurement process, the data transmission that follows will speed up enough to pay off the cost.

802.11n Beamforming was non-standardized, in 802.11ac, there is only one method of beamforming, called the Null Data Packet (NDP). (rb- Read the AeroHive article for a full description of NDP)

Aerohive’s Gast concludes that by steering the energy towards a receiver, beamforming enables you to take a step up to a higher data rate. Mr. Gast estimates that 802.11-based beamforming gives you a 3-5 dB gain.

802.11ac is speedyIn theory, at the 5GHz band with beamforming, 802.11ac should have the same or better range than 802.11n  However, Mr. Anthony says the 5GHz band, has less penetration power so it doesn’t have the same range as 2.4GHz (802.11b/g). The ExtremeTech article concludes that’s an acceptable trade-off: there simply isn’t enough spectral bandwidth in the cluttered 2.4GHz band to allow for 802.11ac’s gigabit-level speeds.

ExtremeTech‘s Anthony calculates there are two answers to how fast is Wi-Fi 802.11ac, the theoretical max speed, and the practical max speed that mere mortals will get surrounded by lots of signal-attenuating obstacles.

He calculates the theoretical max speed of 802.11ac is eight 160MHz 256-QAM channels, each of which is capable of 866.7Mbps – a grand total of 6,933Mbps, or just shy of 7Gbps. That’s a transfer rate of 900 megabytes per second. Compare this with 802.11n’s max theoretical speed, which was 600Mbps. He then says in practice, the current max speed of 802.11ac devices is 1.7Gbps.

ExtremeTech points out there will be a second wave of 802.11ac devices – due in 2014 after the standard is finalized – before 160MHz channels and multi-gigabit speeds become a reality. The max speed over an 80MHz channel is 433.3Mbps, and there aren’t any 802.11ac chipsets that support up to eight streams.

Broadcom logoKevin Fitchard at GigaOM reports that recently the Wi-Fi Alliance kicked off its 802.11ac certification program. First to get the official Wi-Fi stamp of approval was the Samsung Mega 6.3, followed by two other Samsung models.

As with the 802.11n certification process, the Wi-Fi equipment makers are moving faster than the standards bodies. The IEEE is actually still putting the finishing touches on the 802.11ac standard, which is not due until 2014.

Wi-Fi certifiedThe Wi-Fi Alliance expects the first batch of ac devices will support speeds of 433 Mbps and progress into more advanced levels of the standard. The Alliance has pre-certified systems from companies like Broadcom (BRCM), Qualcomm (QCOM), Realtek, and Marvell (MRVL). Cisco (CSCO) was one of the first vendors to get an access point certified.

“AC is going into mobile and portable devices first…,” Wi-Fi Alliance Marketing and Program Management Director Kelly Davis-Felner said. ABI Research estimates that 40 percent of all ac devices shipped in 2013 will be handsets.

Wi-Fi will replace wired Ethernet networkingWhile tech pundits argue that the new 802.11ac Wi-Fi will replace wired gigabit Ethernet networking at home and in the office. While the consumerization of IT and BYOD are strong forces, the life-cycle of cabling infrastructure is 25 years, a cost not lightly abandoned in the walls. it is more likely to happen at home first. Who wants all the crappy wires running all over the house?
