Why predictive maintenance hasn’t taken off as expected

“Two years ago, predictive maintenance was forecast to be one of the most promising uses of the industrial Internet of Things (IoT).”That’s the lead of report based on a recent Bain & Company survey of more than 600 high-tech executives (Beyond Proofs of Concept: Scaling the Industrial IoT, by Bain partners Michael Schallehn, Christopher Schorling, Peter Bowen and Oliver Straehle). The report goes on to note that identifying precisely when equipment might fail “seemed like a no-brainer.” And yet, the report concludes, “predictive maintenance has failed to take off as broadly as expected.” In fact, industrial leaders were not as excited about predictive maintenance as they were back in a 2016 survey.To read this article in full, please click here

Like 4G before it, 5G is being hyped

Just as it did with 4G, AT&T has once again jumped the gun and announced that it was deploying 5G (actually, they’re calling it “5G E”) in twelve cities, only to be challenged by its three major competitors, who claim that AT&T was merely re-branding a faster version of 4G as 5G and misleading the public about the technology.To read this article in full, please click here(Insider Story)

Like 4G before it, 5G is being hyped

Just as it did with 4G, AT&T has once again jumped the gun and announced that it was deploying 5G (actually, they’re calling it 5G+) in 12 cities, while deploying so-called “5GE” in other cities, only to be challenged by its three major competitors, who claim that AT&T was merely re-branding a faster version of 4G as 5G and misleading the public about the technology.To read this article in full, please click here(Insider Story)

BrandPost: Edge Computing is Here to Unlock the Power of your IOT Applications

Gartner defines edge computing as “solutions that facilitate data processing at or near the source of data generation,” a nice, succinct explanation of this booming technology. If you don’t need it already, you most likely will soon as it’s a key enabler of cloud-based applications, including Internet of Things (IoT) applications and others supporting the digital transformation of business.“Organizations that have embarked on a digital business journey have realized that a more decentralized approach is required to address digital business infrastructure requirements,” says Santhosh Rao, principal research analyst at Gartner. “As the volume and velocity of data increases, so too does the inefficiency of streaming all this information to a cloud or data center for processing.”To read this article in full, please click here

Lenovo jumps into the pay-per-use server market

A year ago, every major vendor had a pay-per-use on-premises server as a way to counteract the popularity of cloud vendors — all but Lenovo.Well, no more. The company is launching TruScale, a pay-per-use system for its servers that it says offers true pay-per-use and no requirement of a minimum capacity purchase. TruScale is a subscription-based offering that allows customers to use and pay for data center hardware and services either on premises or at a customer-preferred location without having to purchase the equipment outright. Capacity can be scaled up or down to accommodate business needs automatically. It requires no minimum capacity purchase, which HPE and Dell do require.To read this article in full, please click here

BrandPost: Wi-Fi Next Steps: 802.11ax or 802.11ac?

With a new wireless standard ready and available, 2019 unwraps a wireless conundrum as 802.11ax solutions take their place in the market. You may also hear about Wi-Fi 6, which is just the new nomenclature used by the Wi-Fi Alliance (instead of 802.11ax) in the effort to simplify the naming convention. With a hat tip to iOS, this nomenclature is pretty familiar to mobile users so there’s a good chance we’ll see Wi-Fi 7, 8, and 9 in years to come. For the sake of consistency in our comparison of the two standards discussed here, I will refer to the new standard as 802.11ax.Outside what to call the new standard, Aruba and others have introduced APs that leverage the new performance capabilities of 802.11ax. The new Wi-Fi standard includes some clever engineering that improves performance and saves battery life, but it may not be the right choice, nor the only option, to meet the needs of your midsize organization.To read this article in full, please click here

Red Hat announces container flaw CVE-2019-5736

Red Hat announced a vulnerability this morning – one that can be exploited if a user runs malicious or modified containers. The flaw in runC (a lightweight portable container runtime) and Docker that this vulnerability exposes allows an attacker to escape a container and access the underlying file system. That might sound bad, but there's more.The good news is that this vulnerability cannot be exploited if SELinux is enabled and that this is the default on Red Hat systems. To check whether your Red Hat system is enforcing SELinux, use one of the following commands:$ /usr/sbin/getenforce Enforcing <== $ sestatus SELinux status: enabled <== SELinuxfs mount: /sys/fs/selinux SELinux root directory: /etc/selinux Loaded policy name: targeted Current mode: enforcing Mode from config file: enforcing Policy MLS status: enabled Policy deny_unknown status: allowed Memory protection checking: actual (secure) Max kernel policy version: 31 [ Read also: Linux hardening: A 15-step checklist for a secure Linux server ] This vulnerability also requires local access to the system. Affected Red Hat systems include:To read this article in full, please click here

Cisco pushes silicon photonics for enterprise, webscale networking

Cisco says it's closed its deal to buy optical-semiconductor firm Luxtera for $660 million bringing it the advanced optical technology customers will need for speed and throughput for future data-center and webscale networks.When Cisco announced the deal in December, Rob Salvagno, Cisco vice president of Corporate Business Development, said, “As system port capacity increases from 100GbE to 400GbE and beyond, optics plays an increasingly important role in addressing network infrastructure constraints, particularly density and power requirements.”To read this article in full, please click here

Dell CTO talks modern data centers, the edge, and digital disruption

Dell’s CTO has laid out the company’s vision of where enterprise technology is headed in 2019, and it’s not what people were predicting a few years ago.Gone is the talk of the demise of the data center. Instead, the data center is being repurposed, and some of its tasks are being moved to the edge, said Robert Hormuth, CTO and vice president of Dell EMC Server Infrastructure Solutions. This, he said, is a time to be disruptive before your competition.[ Read also: Edge computing best practices and Edge computing is the place to address a host of IoT security concerns | Get regularly scheduled insights: Sign up for Network World newsletters ] In a recent blog post, Hormuth said IT must be the enabler of the transformational journey for IT. “Businesses must transform and embrace the digital world, or get run over by a new, more agile competitor with a new business model benefiting from advanced technologies like data analytics, AI, ML, and DL. No business is safe from the wave of digital disruption,” he wrote.To read this article in full, please click here

Why are IoT platforms so darn confusing?

Lots of vendors are eager to sell enterprises an “IoT platform,” but it’s not always clear exactly what those “platforms” actually do, why you need one, and which one you should choose. As Hackernoon put it in April 2018: "We’re a cross-functional, fully integrated, full-stack, serverless, hardware agnostic, AI, IoT platform that offers you infinite infrastructure . . .“ said every confusing IoT platform website ever.To read this article in full, please click here

How AI can improve network capacity planning

Network capacity planning aims to ensure that sufficient bandwidth is provisioned, allowing network SLA targets, such as delay, jitter, loss, and availability, to be reliably met. It's a complex, error-prone task with serious financial implications. Until recently, the network data necessary for insightful capacity planning was generally only available via static, historical, after-the-fact reports. This situation is now rapidly changing.To read this article in full, please click here(Insider Story)
