A French company called Accelize has launched AccelStore, an app store specifically around providing custom programmed applications for FPGA accelerators.FPGAs are dedicated processors known for doing two things: very fast processing, and being reprogrammable. CPUs have to be general-purpose processors that run an OS, but an FPGA has the luxury of doing a dedicated task, so the architecture is different.The problem is that while FPGAs are reprogrammable to do new, specific tasks, they aren’t that easy to program. In fact, it’s often pretty hard to do. That’s Accelize’s sales pitch. Rather than writing the code to reprogram the FPGAs in your servers, it has the templates for you.To read this article in full, please click here
Last week, I received an email from Checkfluid, an Ontario, Canada-based enterprise that builds oil quality sensors and oil sampling valves for equipment condition monitoring and predictive maintenance. Like all executives who contact us with good Internet of Things (IoT) questions, Checkfluid’s President Mike Hall was asking my opinion of best-in-class IoT platforms to power his company's journey into IoT. “As we start the product development process, it is important to make the best IoT platform choice possible as this decision could be with us for a long time,” stated Hall. As we know, identifying a high quality, scalable, easy-to-use IoT platform makes a huge difference in an enterprise’s IoT deployment.To read this article in full, please click here
It isn’t hard to find what you’re looking for on a Linux system — a file or a command — but there are a lot of ways to go looking.7 commands to find Linux files
find
The most obvious is undoubtedly the find command, and find has become easier to use than it was years ago. It used to require a starting location for your search, but these days, you can also use find with just a file name or regular expression if you’re willing to confine your search to the local directory.$ find e*
empty
examples.desktop
In this way, it works much like the ls command and isn't doing much of a search.To read this article in full, please click here
The topic of network engineer re-skilling has been front and center for the past few years. Some network professionals have embraced the concept and are leading the network industry in a whole new direction. Others, though, are more resistant and show about as much enthusiasm for this new world as my wife does when I ask her to watch a Star Trek marathon with me.Network professionals need to become software-fluent
Part of the resistance to re-skilling is that change is scary and often hard. Many network engineers have been working a certain way for years, possibly decades, and now they are asking, "Do I need to throw those skills away and learn new ones?" To those people, I say an emphatic YES! It’s absolutely critical to learn new skills today, or you could find yourself quickly looking for a job.To read this article in full, please click here

Internet-based virtual private networks rose to popularity in the 1990s by providing cost-effective connections securely across an insecure internet, and along the way VPNs have provided the impetus for today’s SD-WAN technology.VPN definition
The definition of a virtual private network (VPN) is creating a secure network over network transport that is less secure, such as the internet. [ Click here to find out more about SD-WAN and why you’ll use it one day and learn about WANs and where they’re headed. | Get regularly scheduled insights by signing up for Network World newsletters. ]
VPNs are used to connect two or more nodes in a network and are most commonly used to connect individual users’ machines to sites or to connect sites to sites. It’s possible to connect users to each other, but the use case for that is very limited so such deployments are rare. To read this article in full, please click here
Ask a group of IT leaders to define what a hybrid cloud is, and their answers are likely to be as diverse as the companies they work for. Once a black-and-white definition describing organizations with a mix of apps that reside in both the public cloud and in enterprise data centers, a hybrid cloud has now become much more complicated as the number of apps used in the enterprise grows and their integration requirements mount. The average company uses more than 1,400 cloud services, according to Skyhigh Networks, often because lines of business are being pressured to innovate, leaving little time to develop a strategy for the most efficient and cost-effective way to run them.To read this article in full, please click here

Best-of-breed strategies have long since fallen out of favor in the enterprise, because the work required to stitch together the components proved to be too difficult. But best of breed is back with cloud. Companies today are hell-bent on buying the ideal SaaS, PaaS, and IaaS cloud services for the job, and while APIs make the integration work easier, the resultant cloud silos create a new challenge: How do you assure service performance in this multi-cloud world?The short answer: By maintaining global knowledge of what is happening (and where) across IT infrastructure, applications, and services. But we’ll get back to that.Companies use eight cloud providers on average, according to IHS Markit Ltd., a research firm in London. IHS’ survey of 155 companies in a range of industries shows that number swelling to 11 within two years. When you include any and all SaaS services, the average number of cloud applications that companies use explodes to almost 1,500, by some counts. To read this article in full, please click here
By now, it's pretty clear that cloud migration can yield big benefits. In fact, a recent survey from research firm ESG found that nearly 40% of respondents said migrating reduced data center build-out costs. It also increases resource elasticity and speeds up service provisioning.Reaping those benefits is by no means a sure thing, however. To attain cloud migration nirvana, companies must successfully navigate a host of challenges, including retaining visibility and control over service quality and performance.To read this article in full, please click here
Serverless computing is an emerging trend that is likely to explode in popularity this year. It takes the idea of a smaller server footprint to the next level. First, there were virtual machines, which ran a whole instance of an operating system. Then they were shrunk to containers, which only loaded the bare minimum of the OS required to run the app. This led to a smaller footprint.Now we have “serverless” apps, which is a bit of a misnomer. They still run on a server; they just don’t have a dedicated server, virtual machine, or container running 24/7. They run in a server instance until they complete their task, then shut down. It’s the ultimate in small server footprint and reducing server load.To read this article in full, please click here
Hundreds of megabytes of data have been encoded using DNA in the last few years by scientists. But more recently, not only has the media been stored perfectly in the synthetic variant of the genetic instructions that make up all organic life, but archived data files have been individually retrieved with zero errors, too.It appears that Microsoft Research’s target of a DNA storage system actually functioning within a data center by the turn of the decade, as reported by MIT’s Technological Review a year ago, might be becoming increasingly viable.To read this article in full, please click here

“Friends don't let friends build data centers.”That slogan wasn’t even printed on a real T-shirt you could buy. It was just one of the choices in an online poll to choose what Amazon Web Services CTO Werner Vogels should wear. But it pretty much captured the mood at the AWS Summit San Francisco last week, where Vogels gave the opening keynote to some 9,000 cloud-loving attendees.
On stage, Vogels crowed about multiple enterprises abandoning large numbers of data centers in order to move their workloads to the cloud. He cited Cox Automotive—the company behind Autotrader, Dealer.com, Kelley Blue Book, and many more car-shopping brands—“going all in on AWS” and closing more than 40 data centers. He noted that U.K. news provider News International is shutting down 60 data centers, and GE is closing approximately 30 data centers. And Vogels mentioned that the U.K.’s Ministry of Justice was moving to AWS, as well, though he didn’t say whether it was closing any data centers in the process.To read this article in full, please click here
When thin clients were first introduced to the market in 1995, there was a cultural backlash. Thin clients may have made working with company data less costly and more secure, but from the workers’ perspective, their PC was replaced by a little box connected by a serial cable, with limited graphics that was much slower than the PC they were used to working on every day.In those early days, even as we swapped the serial cables for network ones, shrunk the cases, and doubled the performance, it didn’t take long before thin clients were banished to niche use cases, becoming the territory of call centers, nurses’ stations and manufacturing plants—often to those workers’ disappointment.To read this article in full, please click here
It seems that every three to five years, the impact of inclement weather, storms, and floods appears to peak. And the periods in between weather events seem to be getting shorter. As the number and severity of storms continues to increase far beyond what we have typically experienced, many small and mid-size businesses (SMBs) are now forced to re-evaluate how well their IT infrastructure can continue to support the organization when there is a weather event. This is becoming a critical issue, as many SMBs may find themselves without power for multiple days, which has been the case with the recent nor-easters plaguing the East Coast.Too many SMBs have not assessed the ability of their power and cooling infrastructure to support critical IT equipment in the event of a short- or long-term power outage. Despite frequent and substantial changes at the hardware and application levels, power management and UPS solutions may be decades old. The impact of today’s digital business could not even be conceived of, let alone considered, in the design of these older, legacy backup systems. Further, many of the batteries that provide emergency power haven’t been changed or maintained in years. And many older UPS products Continue reading
IBM is widening its mainframe range with some narrower models – ZR1 and Rockhopper II – that are skinny enough to fit in a standard 19-inch rack, which will answer criticisms of potential customers that the hulking z14 introduced in July 2017 too big to fit in their data centers (see photo above).In addition to new, smaller, packaging for its z14 hardware, IBM is also introducing Secure Service Container technology. This makes use of the z14's encryption accelerator and other security capabilities to protect containerized applications from unwanted interference.[ 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. ]
When IBM introduced the z14 last July, with an accelerator to make encrypting information standard practice in the data center, there was one problem: The mainframe's two-door cabinet was far too deep and too wide to fit in standard data center aisles.To read this article in full, please click here
What’s old is new again. This statement rings true as the industry rallies behind fabric networking again. Fabrics are not a new technology; they’ve been around since 2011/2012. However, we’ve seen increased uptake for fabrics outside of the traditional data center and into the enterprise campus. As the use cases and the technology continue to evolve, this blog clarifies some common misconceptions you may have about fabric technology.1. They are only for the data center
Not anymore. Going back 5-6 years, network fabrics were originally designed to solve how to stretch L2 VLANs across subnets for VM migrations and mobility. We now see far more use cases for network fabrics that extend to the enterprise campus portion of the network. Examples include network automation, zero-touch provisioning, simplified network segmentation, and even high-performance multicast without the use of any complex PIM protocols.To read this article in full, please click here
