Putting unused CPUs to work is nothing new. In the modern era, it started in 1999 when the SETI Institute launched SETI@Home, a screensaver that also examined slices of radio signals gathered by a giant telescope for signs of intergalactic life. Nineteen years later, and ET still hasn’t phoned us.But the concept grew to dozens of science and math-related projects. I took part in the World Community Grid run by IBM for years, letting my idle PC look for potential cures for AIDS and Ebola.To read this article in full, please click here
Five servers that exist thanks to the Open Compute ProjectImage by IDG News ServiceThe Open Compute Project began life when Facebook asked the question, “What if we could design our own servers, rather than having to take what vendors offer?”The answer was a series of designs for servers that would be cheaper to build and operate. Facebook decided that it stood a better chance of finding a manufacturer for its designs if others wanted to buy them too, so with the support of Intel and Rackspace, it opened up its designs and invited others to build and build on them too.To read this article in full, please click here
Reno-based analyst Synergy Research Group released a review of the 2017 cloud market on January 4th. The report, which estimated the total scope of the industry at $180 billion, gauged the year-over-year growth rate of infrastructure as a service (cloud hosting) and platform as a service (combined cloud hardware and software) at 47%. Such astronomical growth in the infrastructure of cloud is fueling growth of data centers. The extent to which cloud is becoming the new form of infrastructure cannot be overstated, with Cisco predicting 95% of data center traffic will be through cloud infrastructure by 2021.To read this article in full, please click here

The technology that powers businesses is evolving faster than ever before, allowing us to do more than we ever thought possible. Things that were once only seen in science fiction movies are actually coming to life.One of these areas is the field of artificial intelligence (AI). We’re on the verge of having machines diagnose cancer, map out the universe, take over dangerous jobs, and drive us around. The downside to the rapid evolution has been a rise in complexity. Putting together the infrastructure and software to power AI-based systems can often take months to build, tune, and tweak so that it runs optimally.Compounding the difficulty is that AI infrastructure is often deployed by data scientists who do not have the same level of technical acumen as the IT team.

Why now? The networking industry is being disrupted.There is an explosion in network demand, driven by ultramobile users who want the ability to access the cloud and consume high-definition content, video, and applications when and where they choose. This disruption of the network will only be exacerbated by the adoption of the Internet of Things (IoT) and 5G, the use of which involves billions of devices interacting with machines, users, and clouds to drive consumer and business interactions.For instance, what happens when users want to engage in a 4K-based virtual reality session hosted in the cloud, while traveling at high speed in their driverless cars? What happens when the physical devices currently used to support networking functions become virtual—and so do the user end-points? Network providers are now realizing the level of complexity and variability this type of demand will introduce, and that their current networks are not up to the challenge.To read this article in full, please click here
Tech companies of every stripe are staking their claim to the internet of things, and networking vendors like Aruba are no exception. But to hear co-founder and president Keerti Melkote tell it, his company’s pitch might have a little more heat on it than others.Aruba’s IoT credentials are based on a relatively simple premise – by definition, IoT devices have to be on the network, and they’re one of the bigger fish in that particular pool.[ Find out how 5G wireless could change networking as we know it and how to deal with networking IoT. | Get regularly scheduled insights by signing up for Network World newsletters. ]

A new study from the Economist Intelligence Unit (EIU) shows that consumers around the world are deeply worried about in how their personal information is collected and shared by the Internet of Things (IoT). But let’s be honest, the problem isn’t that unsophisticated consumers are panicking for no reason. In fact, consumers are merely picking up on the very real inherent risks and uncertainties surrounding IoT data.Businesses are also worried about IoT security
I’ll get into the results and implications of the survey in a moment, but first I want to note that business and professionals are equally concerned. Perhaps that’s why Gartner just predicted that IoT security spending will hit $1.5 billion by the end of the year, up 28 percent from 2017, and more than double to $3.1 billion by 2021.To read this article in full, please click here

The combination of new technology, the emergence of the digital generation, and technology that dramatically reduces the impact of distance on learning has fundamentally changed K-12 education. It’s no longer a case of “engaging with technology,” but technology that actually empowers the learning process.To start, device-based learning is the new normal. Unlike decades ago when the use of technology was limited to an hour a day in the “PC Lab,” devices are now used constantly. And unlike the PC days, these new devices depend on central servers, storage, and the network to deliver the apps and information used for coursework. If your central IT—either the systems or the supporting data center—cannot provide very high levels of reliability, teachers and students will lose valuable class time.To read this article in full, please click here
The Internet of Things (IoT) is projected to grow significantly over the coming years. Research firm Gartner Inc. has estimated that 8.4 billion connected things were in use worldwide in 2017, up 31% from 2016, and expects the number to reach 20.4 billion by 2020.This growth is being driven by the promise of increased insight, enhanced customer satisfaction, and greater efficiency. These benefits are made possible as sensor data from devices and the power of Internet-based cloud services converge. One of the key concerns related to the successful adoption of the IoT is having sufficiently strong security mechanisms in place throughout the ecosystem—to mitigate the increased security risks of connecting devices to the Internet.To read this article in full, please click here
As long as I have been an industry analyst, network engineers have tried to build multifunction boxes that are capable of addressing a wide range of network functions. These all-purpose network boxes have been lost to history as single-function platforms optimized for network performance (e.g., router or WAN optimization) dominated the market. The branch network is poised to benefit from the advances in software networking to collapse all network functions on to a single platform — the software-defined branch (SD-Branch).A total addressable market (TAM) analysis of the SD-Branch market starts with understanding the total spend on branch networking hardware and software. Worldwide spending on routers, WAN optimization, SD-WAN, network security, Wi-Fi, and ethernet switches at branch locations is approximately $15 billion, according to Doyle Research.

Pushing industrial control intelligence to the edge—closer to where manufacturing and production processes are happening—offers tremendous potential for increasing business efficiency and agility. Add in the ability to perform real-time analytics on the plant floor, and the possibilities for optimizing operations are endless.This is not lost on operational technology (OT) professionals. According to a recent market report by ARC Advisory Group, 91 percent of industrial automation users surveyed said that having better systems and connectivity at the edge will improve real-time decision making. Early adopters are moving aggressively to push intelligence to the edge as part of a larger Industrial Internet of things (IIoT) strategy. So why isn’t everyone jumping on the edge computing bandwagon?To read this article in full, please click here

The growth in cloud computing has shone a spotlight on data centers, which already consume at least 7 percent of the global electricity supply and growing, according to some estimates. This has led the IT industry to search for ways of making infrastructure more efficient, including some efforts that attempt to rethink the way computers and data centers are built in the first place.To read this article in full, please click here(Insider Story)
There’s no question that Wi-Fi networks continue to grow in importance for most companies. Workers rely on it to do their jobs, students are being educated on mobile tablets, doctors are pulling up records at a patients' bedside, and millions of Internet of Things (IoT) devices are now being connected to Wi-Fi. Wireless is no longer the connection of convenience — it’s mission critical, and a poor-performing wireless network means a key process is likely to fail.

Composable infrastructure treats compute, storage, and network devices as pools of resources that can be provisioned as needed, depending on what different workloads require for optimum performance. It’s an emerging category of infrastructure that’s aimed at optimizing IT resources and improving business agility.The approach is like a public cloud in that resource capacity is requested and provisioned from shared capacity – except composable infrastructure sits on-premises in an enterprise data center.[ Check out REVIEW: VMware’s vSAN 6.6 and hear IDC’s top 10 data center predictions . | Get regularly scheduled insights by signing up for Network World newsletters. ]
IT resources are treated as services, and the composable aspect refers to the ability to make those resources available on the fly, depending on the needs of different physical, virtual and containerized applications. A management layer is designed to discover and access the pools of compute and storage, ensuring that the right resources are in the right place at the right time.To read this article in full, please click here
In our last two columns, we’ve focused our discussion on industry trends that are impacting storage architectures, as well as a few “broad stroke” architectures that may help businesses address the issues those trends created. For this month’s column (as well as more than a few future ones), I’d like to instead focus on solution strategies for improving and modernizing the storage architectures for today’s businesses.Market drivers for SMB storage
Let’s start with looking at small and midsize businesses (SMBs). By our definition we’re talking about firms with less than 1,000 employees. While that’s hardly FORTUNE 500 territory, firms with hundreds of employees still have a deep need for enterprise-class file storage capabilities. Think design firms, software developers, architectural firms, creative businesses, etc. – all of these SMBs rely on their data and file storage as the lifeblood of their business.To read this article in full, please click here
The notion of disaggregation – separating the operating system and applications from the underlying hardware – has always been a conundrum for Cisco. In a nutshell, why would the company risk losing all of the millions of dollars in development and the key networking features tied up in current Cisco hardware and software packages?But in the new world of all-things software in which Cisco plans to be king, the disaggregation strategy is gaining momentum.

Rarely do I have a conversation about networking when the topic of software-defined WANs (SD-WANs) does not come up. It’s far and away the thing that network professionals care most about, even ahead of data center SDNs.In a data center, enterprises can steer people out of problems as there’s always an abundance of experienced engineers locally available to tackle any issue big or small. That luxury does not exist with the WAN because branch offices can be scattered across the globe and often, the best one can hope for in terms of a local resource is a branch administrator or someone who can check lights or confirm things are plugged in and powered up. Also, for many geographically distributed organizations, the WAN is their business – so having an agile, dynamic WAN that enables applications to perform better is a top priority.To read this article in full, please click here
