Ask Slashdot: What Will IT Look Like In 10 Years?
An anonymous reader writes "The IT industry is a lot different than it was 10 years ago; it underwent a huge boom in terms of labor and services required to keep up with the times. Now, we are entering a consolidation phase. The cloud makes it easier for companies to host e-mail, so now instead of organizations having their own Exchange guy, they will outsource it to the cloud. Instead of having a bunch of network engineers, they will deploy wireless and no longer need cabling or current levels of network engineering services. What do you think the long-term consequences of this will be? What skills do you think will be useful in 10 years? Is IT going to put its own out of work, like we did with the post office and libraries?"
Going to all wireless will require at least as many engineers as now, but they'll have to be even better at it. They'll trade in their cat-5 testers for radio analysers to help them track down leaky ovens, malfunctioning wifi cards, and rogue devices. They'll enter new depths of hell trying to explain to an administrative assistant that the new potted plant in the foil wrapped pot is blocking her network connectivity.
Meanwhile, IT will end up buying a golf cart to help hunt down freeloaders in the parking lot.
Almost every company depends on networked computers to perform critical daily tasks. IT's function is to provide and maintain the computing infrastructure.
Unfortunately, there's MBA types counting beans and looking for places to save money. They look at IT and see a cost center; IT adds nothing to the bottom line.
So let's start with a company with a healthy IT department; since they do their jobs, all the computing resources are up and running, problems are few and far between and quickly resolved.
The bean counters look at the situation and how much they're paying IT - and see that everything is working fine. What are we paying these folks for? Lay them off to save money.
Things keep running for months but start to fall apart around the edges; the users fix some of their PC problems and work around others. At about 18 months or so something critical goes down; the Exchange server takes a crap or something similar. Now they're in a panic; we need qualified IT staff, pronto. So they start hiring again (at a higher pay scale) and the cycle repeats.
Try not to confuse this cycle with the longer cycle that moves computing power from the server to the desktop, then back to the server, back to the desktop and now back to the server. "Cloud" is just BS talk; it's dumb terminals on the desk and everything on the servers (again).
Working in IT is like being in a big game of musical chairs. The pay is good when you're getting paid, but there are gaps between the jobs. Right now isn't good for IT people, but in a year or two...
There will be a lot more agile shops, most of them implementing extreme programming, and making the developer feel even more like they're just part of a production line.
Don't get me wrong, I think parts of Agile are OK, but I've been to far too many interviews in the past where the interviewer thinks that Agile is the be all and end all of programming.
Summation 2
Steve Jobs in his last single interview with Walt Mossberg had a very good example of what is happening with IT right now. It basically goes like this:
The very first cars were trucks. The very first chariots humans built were to hawl food from A to B. They were utility vehicles. Only later, when the vehicles of each age became a commodity, did they turn into everyday passenger vehicles that had a certain mass-availability.
The computer now is doing the same thing, moving from being a tool for workers to being a commodity for everyday use by everyone, not just experts. Experts like us don't like that very much right now, but that's the way it goes. Bizarre IBM age keyboard layouts are finally becoming a thing of the past, UIs are becoming more task focused and the need for abstraction whilst using a 'Post-PC Device' is demising quickly. Even the mouse and the file-system is quickly fading into a specialist tool.
Everyday commodity computing is basically going the way of the iPad.
IT will move to a stronger separation of end-user and expert computing. Workstation-Laptops will become more rare and expensive, purpose built for programmers and admins to use them whilst tablet and netback devices will become a dime a dozen in all kinds of varieties. People won't look for actually performance but for brands of services. Sales talks like this: 'Can my device Twitter, Facebook, Flickr and Netflix?' 'No, it can only Twitter and Facebook, you need an upgrade to Netflix with it.' will become normal at the HiFi-Store or carrier outlet.
Some vendors like Apple, Nintendo or Sony will have a strong vertical lock-in with cushy comfort solutions that require upgrading every 3rd year, others will be more open and more utility focused.
Carriers will get into bed with hardware, software and service brands more often. I expect branding and mindshare to become even more important than today in many places. To emphasize: I wouldn't be surprised if Microsoft moved to the Linux kernel in a few years time and nobody would really care or even notice.
Our kind will specialize more and the rich-client web will get a new boost - as it is happening right now - because the platform diversity mess will be very much 1980ies style also like it is right now again.
All in all I'm not to scared about the way of IT, crazy DRM & patents, Human Rights and eavesdropping laws aside.
It's going to be just as interesting then as it is today.
My 2 cents.

And another factor with wireless is the limited bandwidth. When too many are using wireless at the same time in the same location things slows down considerably.
Even if you have 100Mbps but you share it with 20 people you may end up with 5Mbps. Wireless is also sensitive to electric noise, which makes things worse.
So wired networking will be the primary alternative even in the future. Especially considering that the applications we run today require more and more bandwidth.
If builders built buildings the way programmers wrote programs, then the first woodpecker would destroy civilization.
The anon who wrote this question really should stop eating buzzwords like they are candy, they are rotting what little brain he had to begin with.
Wireless to replace the networking guy? Because wireless is just plug and play right? You just setup one of those magic boxes and voila, the entire office building has zero-config access. That is the level this guy is thinking at, it shows he just hasn't got a clue. Just because you used wireless on your home router doesn't mean you are a networking expert, wireless or otherwise. Setting up wireless access is in fact harder for a big building then wired. Wired is simple, you got a cable, you draw it, you test it, it works. Cable doesn't get interference from a microwave or a factory nearby that runs something every monday. It has no dark spots, no interference. And you know what cable you plugged into which PC. I worked in offices where the visitors wifi was only working in the offices, not in the reception or meeting areas. That is helpful.
He also proposes to move your email into the cloud. Clearly he never worked with regulators who would throw such a fit at handing all your confidential data over to a third party.
This is just another post by some kiddy who heard some buzzwords and thinks his massive experience setting up his mom's computer gives him an insight into what IT support for even a medium sized company is all about.
The future is always just the same. Why? Because things don't change all that much. Take flying cars, do you think they are going to solve grid-lock magically? Right, because the entire skies will be open to them right? Do you want flying cars buzzing over YOUR house? No? Then they will be confined to corridors, highways in the sky, just as congested as roads. Proof? Airliners are already having trouble fitting enough planes into busy areas. Now imagine every jumbojet replaced by 300 individuals in the skies.
IT hasn't changed all that much. Even if you go wireless and into the cloud it will STILL require an admin on the ground to deal with it all. Just look at how often Amazon's cloud has been down. If you been in IT a little bit longer then this baby anon, you will know that IT is always changing and changing back again. From mainframe to PC's to the network to the cloud... it is just the latest craze. So the cable puller now pulls a cable to the wireless box and spends his time not checking cable but reception. Big whoop.

You may solo them, I prefer them in a group.
Some time in the next 10 years somebody will crack the "problem" of micropayments: fractions of a penny. Once that happens then pretty much every website will cost something to visit - the commercial imperatives are too high for it to be otherwise. Apps will also charge on a per-use basis, rather than a buy once and use forever principle.
Once sites can charge 0.05p for a visitor to view a page, both the need for advertisers and the attraction they offer will become obsolete. Websites will make their money directly, and the iron grip around their testicles will pass from the search engines that pass them advertising eyeballs, to the brokers that process their micropayments - though there will be huge battles between the old regime: of Google and it's friends and the newcomers, from wherever they come.
I would expect the transition to be particularly painful, especially during the time when there are two iron-grips (one on each 'nad?) pulling in different directions. The resolution will come when part of the micropayment can be passed on to the referrer - whether search engine or linking site, in lieu of their lost advertising revenue - though we can expect the landscape of the 202x's to be a lot different, in terms of which companies are dominant.

I nearly fell out of my chair laughing about wireless precluding the need for network engineers. Do you have even the slightest clue what your network engineers do? I'll give you a hint: not cable runs. You can get some guy making less than $15 an hour to pull cables through walls and climb in attics. Why would you need somebody with any technical inclination at all to do that?
Your network engineers are there for ensuring cross-node connectivity and security. When I set up your routes, manage your IPSEC tunnels, and design your firewall rules, I don't give two shits about what you are using for physical connectivity. You could have some cups attached together with strings and it wouldn't change my network design.
In fact, wireless gives me more work to do. Wireless setup, while easy, takes more configuration than plugging a wire into a port. And if your building is of any size and thick construction, I'm going to require a lot more networking nodes to service the whole thing adequately than I need when I can run 300 feet in any direction with a cable. Which means if your douchebag veeps want to be able to walk around the building with their iThingies, I have to make sure the pieces of junk can connect to any wifi hotspot in the building, which is its own set of headaches.
And then there's security. Wireless is an external attack vendor. Yes, it's cute that you think that encrypting your radio signals makes it impossible to eavesdrop. It's even more awesome when somebody somewhere demands that I reduce encryption levels because some older device they have can't even handle WPA2/AES. But here's the thing: bad guys can now sit out in the parking lot and collect your encrypted traffic undetectably. If they use some directional antennas and some feed horns, they might even be able to get farther away. After that, they can sit back and try to brute force your wireless key using their GPUs from the comfort of their homes. After that, they could perform corporate espionage from the cafe next door and if they play their cards right, there is not a damn thing you can do to even tell they are doing it.
I have never set up wireless that was directly attached to somebody's corporate network. When I set up a wifi hotspot at somebody's business, it gives them access to the internet and the internet only. They can securely VPN after that if they want to get to company data.
Does this all still sound like you can just plug in some Linksys routers you got from Fry's and fire your networking guy?
