Hyperconvergence is winning over enterprises that are drawn to its potential to ease management, streamline the deployment of new workloads, and optimize infrastructure costs.As much as 20 percent of business-critical applications currently deployed on three-tier IT infrastructure will transition to hyperconverged infrastructure by 2020, predicts Gartner, which recently gave the technology its own magic quadrant.[ Check out our What is hyperconvergence? and learn whether your network and team are up to hyperconverged storage. ] The magic quadrant is Gartner’s signature format for tech market analysis, and in prior years, the research firm tackled hyperconvergence as part of its integrated-systems research.To read this article in full, please click here

IDG Contributor Network: Software-defined everything

Digital transformation is ushering in what the organizers of this year’s Pacific Telecommunications Council’s (PTC) 2018 global conference called “a new decade of connections.” The global trends driving digital include greater technology use, urbanization, data sovereignty, cybersecurity and global trade of digital services, as reported in the Global Interconnection Index, a market study published by Equinix. These macro trends are behind the creation of increasing amounts of data coming from new sources, such as digital media, artificial intelligence/machine learning (AI/ML), big data and security analytics, augmented/virtual reality and the Internet of Things (IoT).To read this article in full, please click here

What do ogres, onions and SD-WAN security have in common? Layers!

Remember this scene from the movie Shrek? The big ogre was explaining to Donkey that ogres are very complicated, and like onions, they have layers. Donkey, of course, didn’t like the analogy because not everyone likes onions and would have preferred cake as everyone likes cake, but he did seem to understand that ogres did indeed have layers after it was explained to him. Orges and onions have layers, but what else does? Or at least should? Security for SD-WANs — but that may not seem obvious to everyone.Also read: The case for securing the SD-WAN | Sign up: Get the latest tech news sent directly to your in-box This week SD-WAN provider, Aryaka, which is now neck and neck with VeloCloud/VMware in market share, according to IHS Markit, announced Passport, a multi-layered security platform and ecosystem that provides best-of-breed security at every level of a software-defined WAN (SD-WAN).To read this article in full, please click here

The internet of useful things

The industrial internet of things is growingImage by Peter Sayer/IDGWhen we talk about the internet of things, consumer applications too often get the lion’s share of the attention. But there are also a growing number of industrial applications for IoT technologies, from building better mousetraps to preventing theft of manhole covers.To read this article in full, please click here

IDG Contributor Network: Disposable IoT ready to open new opportunities

The Internet of Things (IoT) has transformed how industries operate and how people interact with one another. We have seen an impressive array of new IoT deployments from an explosion of smart city applications across the U.S., to sensors implanted in the horns of critically-endangered rhinos in Africa. The evolution of IoT has connected devices at record speed and provided useful business intelligence to solve complex, real-world problems.IoT devices outnumbered the world’s population for the first time this year. In a recent report, worldwide spending for IoT in 2017 is estimated to have grown 16.7% reaching $800 billion with an expected total of $1.4 trillion per year by 2021. The proliferation of IoT devices can be attributed to the fact that it is now much cheaper and easier to gather information from sensors.To read this article in full, please click here

Big trouble down on the IoT farm

You would think that modern farms would be fertile ground for the Internet of Things (IoT). And in many ways, you’d be right: Smart tractors and other farm equipment, coupled with GPS-equipped smart sensors tracking everything temperature to moisture to soil acidity, mean the IoT can help today’s high-tech farmers plant and harvest more efficiently than ever before.Who benefits from IoT on the farm? But if you believe a recent expose in Motherboard, all is not well down on the IoT farm. It turns out that many of the benefits of IoT — and the big data it generates — in agriculture fall not to the farmers, but to the so-called BigAg equipment makers and seed and fertilizer companies.To read this article in full, please click here

BrandPost: Can an SMB Really Afford IT Downtime

A recent blog post about the negative impact of a 1990s server room talked about downtime and its tremendous impact on any organization. It is now incumbent upon the IT team to do all it can to ensure that IT systems—and the infrastructure that supports them—are as reliable as possible. The spread of digital systems to every aspect of the business makes any service interruption a serious problem for all employees and many of your customers.Small and midsize businesses (SMBs) depend on their servers, storage, and network equipment to keep the company running, but failures do occur. In many cases, these outages result not from the equipment itself, but the racks, cooling, and power infrastructure on which this equipment depends. Based on research from the Institute, cooling and power failures that result from outmoded rack or data center infrastructure cause more than one-third of all unplanned outages. However, an outage is more than just an interruption in business operations; it can result in substantial data loss. To read this article in full, please click here

A few buckets of cold water on the Broadcom-Qualcomm-Intel merger talk

The M&A activity in the chip business isn’t restricted to the big guys snapping up promising startups. The titans are talking marriage, but really, there should be no merger between any of the three giants that are Intel, Broadcom, and Qualcomm.On Friday, The Wall Street Journal reported that Intel was closely watching Broadcom’s hostile bid for Qualcomm in the hopes that Broadcom would fail so it could buy Broadcom. The deal would be valued at an insane $170 billion.Intel issued a denial over the weekend, saying it was only looking to assimilate and absorb several recent acquisitions.The White House steps in, stops Broadcom-Qualcomm merger Meanwhile, the Broadcom-Qualcomm talks persisted despite Qualcomm’s resistance to the idea until Monday, when President Donald Trump issued an executive order blocking the merger, citing national security concerns. I didn’t think he could do that.To read this article in full, please click here

IDG Contributor Network: 11 ways to stabilize your infrastructure

What do you do if you’re struggling with infrastructure and stability? Maybe you’re a startup with no time for infrastructure. Maybe you’re a business that is reluctant to invest, with an IT gap that is hard to close. The stress, the worry and the escalation calls can keep you up at night – and then beat you down the next day.To regain your balance, first take a deep breath. Then consider these 11 steps to help you better align the people, processes and technology around your IT infrastructure: Reduce IT complexity. In a recent survey of 800 CIOs, more than three out of four say increased IT complexity could make it impossible to manage digital performance. Indeed, a single web transaction may now cross an average of 35 different technology systems, up from 22 five years ago. Is that sustainable? If you’re unable to handle your current level of complexity, review your operations, peel back the layers and make sure you’re building from a solid foundation. Delegate. Assign members of your team to key activities. Make sure they are enabled and understand they have authority to solve problems. It sounds simple, but many entry-level IT professionals worry that Continue reading

A new telepresence robot takes the stage

AvaⓇ Robotics, a startup with strong technical ties to iRobot, has just announced its telepresence robot. Her name is Ava and she’s likely to win a lot of hearts. For one thing, Ava is quite perceptive, using video technology from Cisco and integrating with Cisco Spark (which provides tools for team messaging, online meetings, and white boarding). Ava is also quite friendly. She allows her users to participate in remote meetings, wander down hallways at other facilities while chatting with colleagues, and enjoy face to face discussions with people who may physically be thousands of miles away.Telepresence robots provide a lot of benefits to companies that are spread across many locations – especially those spanning continents -- or with staff who work from home. They make work relationships considerably more productive -- even for individuals who may have never met in person. Carrying on casual conversations and checking remote data centers and manufacturing facilities (sometimes safer than being there in person) can make huge differences in how staffs coordinate and get important work done.To read this article in full, please click here

How Microsoft can enable the internet of things

As the Internet of Things (IoT) phenomenon continues to grow, Microsoft has responded by contributing two new editions of Windows 10 – Core and Enterprise –  that are aimed at radically different parts of the devices and systems market.Here's how Windows 10 IoT is used today, and where it might be going in the future.Windows 10 IoT Core The Core edition is a barebones Windows kernel that has been stripped down significantly in order to run on low-power hardware. It is not a full version of Windows, but it is enough to light up the hardware and run whatever application is being designed for that board. This version of Windows 10 has no shell and essentially supports only universal apps – those coded to run in the managed environment of the Universal Windows Platform (UWP) and NOT traditional x86 or x64 apps. This OS version supports a maximum of 256MB of RAM and 2GB of device storage and can run on the x86 chip platform or the ARM platform for low-power devices.To read this article in full, please click here

How to check your network connections on Linux

The ip command has a lot to tell you about the configuration and state of your network connections, but what do all those words and numbers mean? Let’s take a deep dive in and see what all the displayed values are trying to tell you.When you use the ip a (or ip addr) command to get information on all the network interfaces on your system, you're going to see something like this:$ ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: enp0s25: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 00:1e:4f:c8:43:fc brd ff:ff:ff:ff:ff:ff inet brd scope global dynamic enp0s25 valid_lft 57295sec preferred_lft 57295sec inet6 fe80::2c8e:1de0:a862:14fd/64 scope link valid_lft forever preferred_lft forever The two interfaces on this system — the loopback (lo) and network (enp0s25) — are displayed along with a lot of stats. The "lo" interface is clearly the loopback. We can see the loopback IPv4 address ( and the loopback Continue reading

IDG Contributor Network: The delivery challenges every SD-WAN project must consider

It’s no secret that enterprises are looking at SD-WAN as the means for evolving their networks. The technology improves on MPLS with better agility, more capacity increased resiliency and, of course, cost savings. Those advantages are in much need; just ask anyone who’s runs an MPLS network. They’ll tell you about its high costs, long provisioning times, and susceptibility to last-mile failures.But keep listening and MPLS customers are also bound to talk about the technology’s rock-solid reliability. They’ll hate the price and delays, but they’ll love their SLA-backed performance and how the MPLS provider takes care of everything — the last mile connectivity, managing the backbone, consolidated billing and more.To read this article in full, please click here

IDG Contributor Network: How edge computing makes voice assistants faster and more powerful

Voice is becoming a pervasive way to manage and interact with everyday tech devices, going from initial adoption in phones and smart speakers toward smartwatches, cars, laptops, home appliances and much more.Cloud platforms take most of the praise for enabling voice assistant services such as Amazon Alexa, Google Assistant or Microsoft Cortana – neglecting due credit to the increasing role that edge computing plays in enabling voice interfaces. A substantial amount of processing and analysis occur on devices themselves to allow users to interface with them by simply talking.Keyword detection Voice-enabled devices are not constantly recording audio and sending it to the cloud to determine if someone is giving them an instruction. That would not only be a privacy concern, but also a waste of energy, computing and network resources. Having to send all words to the cloud and back also introduces latency and slows the responsiveness of the system. Today’s voice interfaces typically use keyword or “wake-word” detection, dedicating a small portion of edge computing resources (i.e. computing done on the device itself or “at the edge”) to process microphone signals while the rest of the system remains idle. This is a power-efficient approach particularly important Continue reading

Marvell revs up Ethernet to 400Gbps with new ‘Alaska’ chips

Marvell Semiconductor is the first semiconductor to ship networking chips supporting the 802.3cd standard that will pump up Ethernet ports to 400Gbps max.The 802.3cd standard is designed to eventually replace the current physical Ethernet ports, which run at 25Gbps to 100Gpbs, with ports that will run at 50Gbps, 200Gbps, and 400Gbps.And Marvell is the first chip vendor out of the gate with support for the standard in its Alaska C 88X7120 transceivers. The chips aren’t fully cooked, but they are sampling to customers. Sampling is to semiconductors what beta testing is to software.To read this article in full, please click here

Cisco attacks SD-WAN with software from Viptela, Meraki acquisitions

Cisco this week took the wraps off new software packages it claims will help customers manage their biggest networking blind spot: the software-defined wide area network or SD-WAN.The SD-WAN is typically made of diverse networks and technologies that many times are outside the control of IT.  Add to that the increased use of multi-cloud services and other advances, and the traditional complexity of the WAN has been increased, Cisco stated.+RELATED: SD-WAN: What it is and why you'll use it some day; How to negotiate a Cisco Enterprise Agreement that works for you+To read this article in full, please click here

BrandPost: What is Programmable Infrastructure?

In an increasingly mobile world, network providers are grappling with a data explosion. Millions of mobile users are running video and other applications that require significant bandwidth.At the same time, those providers are saddled with legacy systems and protocols that leave them bloated and slow. Even to add simple services, they have to contend with hundreds of manual processes for set up, revisions, and tear down of even the simplest services.With challenges like that, anticipating and responding to dynamic traffic levels and service requests is nearly impossible. These legacy networks simply cannot handle the growing and unpredictable demands on providers, and the problem is only going to worsen.To read this article in full, please click here

VMware tackles complexity of multi-cloud environments

At the same time, VMware announced the first global expansion of VMware Cloud on AWS, its joint hybrid cloud service with Amazon Web Services.Complexity is on the rise for enterprises as they expand their use of cloud computing – which often is not limited to a single cloud provider. VMware estimates that nearly two-thirds of companies will use two or more cloud service providers in addition to their on-premises data centers.To read this article in full, please click here

Why a bare-metal cloud provider might be just what you need

Cloud services, particularly infrastructure- and platform-as-a-service, are well established, but in some cases customers demand more – more control, more access to hardware, more performance, and the ability to pick their own operating environment.In those cases they are looking to bare-metal servcies, a niche that is growing fast.As the name implies, bare metal means no software just CPUs, memory, and storage. Customers provide all of the software from the operating system on up. That means a dedicated CPU, full access to the hardware, and freedom to run custom operating systems.According to a 2016 Markets and Markets report, the bare metal cloud market is expected to grow from $871.8 million in 2016 to $4.7 billion in 2021, at an estimated compound annual growth rate of 40.1%.To read this article in full, please click here

New tech harvests electricity out of thin air

Ambient temperature changes, which take place natively in the environment, could power Internet of Things (IoT) sensors indefinitely, say researchers.The remarkable concept, which the inventors at the Massachusetts Institute of Technology (MIT) call thermal resonating, is highly flexible — unlike previous scientific attempts at developing similar things.It essentially harvests electricity out of thin air, the group claims. No batteries or solar panel-requiring sunlight is needed.To read this article in full, please click here
