Exactly six years ago today\u2014Sept. 5, 2013\u2014Network World published my very first TechWatch blog post. It addressed the introduction of Samsung's Galaxy Gear and the problem with smartwatches.\nSince then, I\u2019ve written hundreds of blog posts on a dizzying array of technology topics, ranging from net neutrality to phablets to cloud computing to big data to the internet of things (IoT)\u2014and many, many more. It\u2019s been a great ride, and I will be forever grateful to my amazing editors at Network World and everyone who\u2019s taken the time to read my work. But all good things must come to an end, and this will be my last TechWatch post for Network World.\nYou see, writing for Network World is not my day job. For the last five and a half years, I have been editor in chief of New Relic, a leader in the enterprise observability space. But this week, I\u2019ve taken a new position at director of content for Redis Labs, the home of the fast Redis database. I\u2019m super excited about the opportunity, but here\u2019s the thing: Redis Labs has a number of products in the IoT space, which could raise thorny conflict-of-interest questions for many blog posts I might write.\n\nLooking back: What technology has changed and what hasn\u2019t\nSo, for this good-bye post, I want to look back at some of the topics I\u2019ve touched on over the years\u2014and especially that first year\u2014and see how far we\u2019ve come, and maybe get a sense of what\u2019s coming next.\nObviously, there\u2019s no time or space to revisit everything. But I do want to touch on six key themes.\n1. Wearable tech\nBack when I wrote that first post on Samsung's Galaxy Gear, it seemed like wearable technology was about to change everything. Smartwatches and fitness trackers were being introduced by everyone from tech companies to sporting goods manufacturers to fashion brands and luxury watch companies. The epic failure of Google Glass hadn\u2019t yet set the category back a decade by permanently creeping out folks around the world.\nToday, things look very different. The Apple Watch is thriving in a limited role as a fitness and health tracking device, trailed by a variety of simpler, cheaper options. Google Glass and its ilk are niche products looking for industrial applications. And my grand vision of wearable tech fundamentally reshaping the technology landscape? Yeah, we\u2019re still waiting for that.\n2. Phones & phablets & tablets\nSix years ago, I had a lot of phun making puns about the rise of \u201cphablets,\u201d those giant phones (or miniature tablets) threatening to take over the mobile world. Well, that happened. In fact, it happened so thoroughly that no one even talks about increasingly ginormous phones as phablets anymore. They\u2019re just\u2026 phones.\n\n3. BYOD and shadow IT\nBack in 2013, shadow IT was still mostly thought of as Bring Your Own Device, but increasingly powerful online services have expanded the concept far beyond enterprise workers using their own phones on the corporate network. Now, shadow IT includes everything from computing power and storage in the cloud to virtually Everything-as-a-Service. And with the rise of Shadow IoT, the situation is only getting more complicated for IT teams. How do you maintain order and security while also empowering users with maximum productivity?\n\n4. Net neutrality\nHoo-boy. After endless arguments rooted in deeply differing versions of what freedom really means, ideological conflicts, all-out business battles between communications companies and online services, net neutrality was finally settled as official U.S. policy. And then, suddenly, all that was changed by a new administration and a new FCC leader. At least for now. Probably. Ahhh, who are we kidding? We\u2019re going to be arguing over net neutrality forever.\n\n5. The cloud\nWhen I started writing TechWatch, the cloud was still a good idea looking to find its rightful place in a world still dominated by private data centers. Today, everything has flipped. The cloud is now pretty much the default for new IT infrastructure workloads, and it is slowly but surely chipping away at all those legacy, mission-critical apps and systems. Sure, key questions around cost, security, compliance and reliability remain, but as 2019 begins to wind down, the cloud\u2019s promise of radical improvements in development speed and agility can no longer be questioned. As cloud providers keep growing like weeds on steroids, modern IT leaders increasingly have to justify notdoing things in the cloud.\n\n6. The internet of things\nTechWatch has been interested in the IoT for a while now (see How the Internet of Things will \u2013 and won't \u2013 change IT), but for the last couple years it has been the dominant topic for TechWatch. Over that time, the IoT has evolved from a concept with tremendous promise but limited real-world applications to one of the most important technologies on the planet, on pace to disrupt everything from brushing your teeth to driving (or not driving) your car to maintaining jet airplanes. It\u2019s been a wild ride, but serious barriers remain. IoT security concerns, especially on the consumer side, still threaten IoT adoption. Lack of interoperability and unclear ROI continue to slow IoT installations.\nBut those are just speed bumps. Like it or not, the IoT is going to keep growing. And that growth won\u2019t always come in nicely defined, easily understood and controlled ways. In many cases, IoT devices and networks are being deployed without established goals, metrics, controls, and contingency plans. It may be a recipe for trouble, but it\u2019s also how just about every important technology rolls out. The winners will be the organizations that figure out how to maximize the IoT\u2019s value while avoiding its pitfalls. I will be watching closely to see what happens!
