IoT gets smarter but still needs backend analytics

One way of looking at IoT deployments is this – a large array of not-particularly-sophisticated endpoints, mindlessly sending individual data points like temperature and pressure levels to either an edge device somewhere on a factory floor, or all the way out to a cloud back-end or data center.And that’s largely correct, in many cases, but it’s increasingly not the whole story – IoT endpoints are getting closer and closer to the ability to do their own analysis, leading to simpler architectures and more responsive systems. It’s not the right fit for every use case, but there are types of IoT implementation that are already putting the responsibility for the customizing their own metrics on the devices themselves, and more that could be a fit for such an architecture.To read this article in full, please click here

Chip shrinking hits a wall — what it means for you

The semiconductor world is buzzing over the news that custom semiconductor manufacturer GlobalFoundries, the foundry born when AMD divested itself of its fabrication facilities, announced the sudden decision to drop its 7nm FinFET development program and restructure its R&D teams around “enhanced portfolio initiatives.”For now, GlobalFoundries will stick to 12 and 14nm manufacturing. All told, approximately 5 percent (of roughly 18,000 employees) will lose their jobs. But it also sets back AMD, a GlobalFoundries customer, in its bid to get ahead of Intel, which has struggled for two years to get to 10nm and won’t get there until 2020.“The vast majority of today’s fabless customers are looking to get more value out of each technology generation to leverage the substantial investments required to design into each technology node. Essentially, these nodes are transitioning to design platforms serving multiple waves of applications, giving each node greater longevity. This industry dynamic has resulted in fewer fabless clients designing into the outer limits of Moore’s Law,” said Thomas Caulfield, who was named CEO of GlobalFoundries last March, in a statement.To read this article in full, please click here

Data center staff are aging faster than the equipment

What is rapidly aging and largely male? If you said the heavy metal music scene, you wouldn’t be wrong (c’est moi), but that’s not the answer in this instance. It’s data center staffing.In its recent report on data center efficiency, Uptime Institute focused primarily on outages and the improvement in power efficiency, but there were other interesting findings, such as this:Data center staff are getting older on average, and women show no interest in the job.[ Now read: 20 hot jobs ambitious IT pros should shoot for ] New skills needed for hybrid IT environments According to the report, there is a growing need for new skills in an increasingly hybrid IT environment. New skills, such as overseeing and managing SLAs for off-premises workloads, are needed, but people don’t have them. Just 35 percent of survey respondents reported that they did not have any of the hiring or staffing issues identified by Uptime.To read this article in full, please click here

BrandPost: Is It Time to Replace Your Network’s Annual Check-Up?

Ciena Daniele Loffreda, Senior Advisor, Industry Marketing The evolution toward a more holistic, personalized health maintenance program will create an explosion of data putting more pressure on our communication networks. Is your network healthy enough to make the sharing of this information possible? Ciena’s Daniele Loffreda discusses.In the past, an annual visit to our primary care doctor was considered common practice. But in today's era of personalized, precision medicine, the annual checkup may not be as necessary for otherwise healthy adults. In fact, research conducted by the Cochrane Collaboration suggests that yearly visits in the absence of symptoms are not beneficial. According to the National Center for Policy Analysis, patients in the United States visit their physicians for annual checkups more than 44 million times per year despite having no medical issues or concerns.To read this article in full, please click here

NASA to use data lasers to beam data from space to Earth

Starting in 2019, NASA will begin using laser communications technology to "enable greater return of science data from space." The reason is laser is more bandwidth-friendly than classic radio for data delivery, plus it's more secure, NASA says in a newly released explainer of its plans.Laser signals from space will be much harder to hack than old-school radio because the signal is more concentrated, the agency says on its website. Plus, the higher frequencies provide more bandwidth — important for space data crunching. And laser equipment is lighter, allowing for longer missions, among other benefits.To read this article in full, please click here

BrandPost: Beyond the Firewall – Different Rules for East-West Traffic

Network firewalls were created to block unauthorized content and code from the network while ensuring the unimpeded flow of data packets vital to the operations of the enterprise. But they were designed to intercept external incursion, not prevent security issues inside the network.“As server virtualization has increased in popularity, the amount of traffic moving laterally across the data center (East-West) has dwarfed traditional client-server traffic, which moves in and out (North-South),” industry analyst Zeus Kerravala writes in Network World. “This is playing havoc with data center managers as they attempt to meet the demands of this era of IT.”To read this article in full, please click here

Ideas this bad could kill the Internet of Things

What’s the silliest, dumbest, most ridiculous Internet of Things (IoT) application you can think of? Smart toothbrushes? Internet-connected toilets? Digital notepads in the shower?Well, forget all that. Heck, you can even forget the "smart" Air Dresser wardrobe that Samsung announced earlier this month. (If you’re wondering, this digital closet is said to automatically "air" — whatever that means — steam, dry, and purify clothes so they don’t, you know, stink.)IBM has just patented an IoT device concept so incredibly inane that it makes all those earlier attempts to trivialize the IoT seem like cures for cancer. What could possibly be so ill-conceived as to make a smart hairbrush look, well, smart?To read this article in full, please click here

IDG Contributor Network: The future of devops for network engineers

If you still live in a world of the script-driven approach for both service provider and enterprise networks, you are going to reach limits. There is only so far you can go alone. It creates a gap that lacks modeling and database at a higher layer. Production-grade service provider and enterprise networks require a production-grade automation framework. In today's environment, the network infrastructure acts as the core centerpiece, providing critical connection points. Over time, the role of infrastructure has expanded substantially. In the present day, it largely influences the critical business functions for both the service provider and enterprise environments. To read this article in full, please click here

IDG Contributor Network: Preparing your network for the hybrid world – 4 imminent IT shifts and the role of NPMD

To the surprise of many not living it every day, a robust, resilient, and reliable network is one of the most important drivers behind success in today’s business world. Organizations must continuously improve their network infrastructure to better meet organizational requirements and offer the experiences their customers expect. Recent changes in the network market mean this continuous improvement needs to go beyond optimizations and extend all the way to re-architecting the network.The forces driving network re-architecture are twofold: new demands on the network, and innovations in network technology and solutions. These new demands on the network stem from enterprise-wide digital transformation initiatives such as cloud, SD-WAN, machine learning and AI, IoT, edge computing, and more. While these new requirements offer a host of business benefits, they’re also introducing disruptive complexity to the network, driving the need to simplify and accelerate the way all IT services are delivered today.To read this article in full, please click here

Dell EMC rolls out future-proofed high-performance servers

If a company needs more or less compute, it can reprovision that resource on the fly to avoid overprovisioning and wasted assets.To read this article in full, please click here

IDG Contributor Network: Does your network have a trade imbalance?

Network traffic, by nature, is often unbalanced. For example, a client that requests a video on demand may receive ten times more bandwidth than it sends for that service. Likewise, most web applications are very one-sided, with the bulk of the traffic being from server to client. The opposite is true for many backup applications, where the bulk of the traffic originates at the client and terminates at the server.The United States is like your network – suffering from a trade imbalance. For every packet we ship to a foreign network, we are receiving four or five in return. Just as there are barriers to trade, we apply barriers to our inbound traffic. The barrier for most of us is the actual size of our Internet service interface. Packets queue up and drop at our carrier’s equipment prior to even being seen by our equipment. If you purchase a 50Meg download speed, any packets that arrive at a faster rate (even for a sub-second of time) will be dropped without prejudice. This is a barrier, restriction and tariff on your services that limit your business. The only solution – buy more bandwidth!To read this article in full, please Continue reading

BrandPost: Why Smart Cities Need Adaptable Pipes

Daniele Loffreda, Senior Advisor, Industry Marketing For cities to evolve and realize the full benefits of becoming “smart,” they will require real-time access to multiple sources of data from different locations. Ciena’s Daniele Loffreda explains what is needed from the next-generation of networks to make smart cities a reality.Apple CEO, Tim Cook, said it best during a commencement address at the prestigious Massachusetts Institute of Technology (MIT) last year when he proclaimed science and technology are worthless, if they aren’t motivated by the desire to help people. This belief can be just as correctly applied to the planning and development of smart city initiatives.To read this article in full, please click here

DHCP defined and how it works

The ability to network devices quickly and easily is critical in a hyper-connected world, and although it has been around for decades, DHCP remains an essential method to ensure that devices are able to join networks and are configured correctly. DHCP greatly reduces the errors that are made when IP addresses are assigned manually, and can stretch IP addresses by limiting how long a device can keep an individual IP address. [ Now read 20 hot jobs ambitious IT pros should shoot for. ] DHCP definition DHCP stands for dynamic host configuration protocol and is a network protocol used on IP networks where a DHCP server automatically assigns an IP address and other information to each host on the network so they can communicate efficiently with other endpoints.To read this article in full, please click here
