How to use the Linux uniq command

In Linux, the uniq command can help find out the individual users who are logged into a given server, but it’s not a straightforward process.Yes, using the command on its own yields a list of who’s logged in, but it can list individual users more than once depending on what they’re doing.There are ways to get around this by sorting the results of uniq so they deliver only once the names of all the users. This 2-Minute Linux Tip video by Network World’s Unix as a Second Language blogger Sandra Henry Stocker shows how to do just that. Click below.

Space-data-as-a-service gets going

Upcoming space commercialization will require hardened edge-computing environments in a small footprint with robust links back to Earth, says vendor OrbitsEdge, which recently announced that it had started collaborating with Hewlett Packard Enterprise on computing-in-orbit solutions.OrbitsEdge says it’s the first to provide a commercial data-center environment for installing in orbit, and will be using HPE’s Edgeline Converged Edge System in a hardened, satellite micro-data-center platform that it’s selling called SatFrame.To read this article in full, please click here

Cisco targets hyperscalers with silicon, high-end routers

Cisco says it wants to change the future of the Internet and has rolled out the new silicon, hardware and software it says will move toward that goal.The centerpiece of Cisco’s strategy revolves around its custom Silicon One chip technology and new Cisco 8000 Series carrier-class routers built on that silicon, which the company says has been in development for more than five years, at a cost of over $1 billion. The 8000s feature a new operating system – IOS XR7 that runs the boxes and handles security.Network pros react to new Cisco certification curriculum The Cisco Silicon One Q100 optical-routing silicon brings up to 10Tbps of network bandwidth in its first iteration – with a future goal of 25Tbps – and support for large non-blocking distributed routers, deep buffering with rich QoS and programmable forwarding. To read this article in full, please click here

What’s hot at the edge for 2020? Everything

Few areas of the enterprise face as much churn as the edge of the network.  Experts say a variety of challenges drive this change – from increased SD-WAN access demand to cloud interconnected resources and IoT, the traditional perimeter of the enterprise is shifting radically and will continue to do so throughout 2020.One indicator: Gartner research that says by 2023, more than 50% of enterprise-generated data will be created and processed outside the data center or cloud, up from less than 10% in 2019.To read this article in full, please click here

IDG Contributor Network: Secure SD-WAN: The security vendors and their SD-WAN offerings

During its inception, we had the early adopters and pure SD-WAN players. Soon it became obvious that something was missing, and that missing component was “security.” However, security vendors have highlighted the importance of security from the very beginning.Today, the market seems to be moving in the direction where the security vendors are focusing on delivering SD-WAN features around pervasive security. The Magic Quadrant for WAN Edge Infrastructure has made a substantial prediction. It states, “By 2024, 50% of new firewall purchases in distributed enterprises will utilize SD-WAN features with the growing adoption of cloud-based services, up from less than 20% today.”To read this article in full, please click here

Passive optical networking: Its day is dawning

The concept of using passive optical LANs in enterprise campuses has been around for years, but hasn’t taken off taken off because most businesses consider all-fiber networks to be overkill for their needs. I’ve followed this market for the better part of two decades, and now I believe we’re on the cusp of seeing POL go mainstream, starting in certain verticals.The primary driver of change from copper to optical is that the demands on the network have evolved. Every company now considers its network to be business critical where just a few years ago, it was considered best effort in nature.  Downtime or a congested network meant inconvenienced users, but today they mean the business is likely losing big money.To read this article in full, please click here

Private 5G keeps Whirlpool driverless vehicles rolling

5G promises super-fast connections, low latency and better coverage. In the manufacturing realm, early adopter Whirlpool is deploying a private 5G network in one its Ohio factories to solve a major problem: Driverless vehicles inside the plant rely on Wi-Fi to navigate, and they stop dead when the factory environment causes the signal to degrade. The sidelined vehicles create traffic jams, slow down production, and require hands-on attention before they can resume delivering parts.To read this article in full, please click here

5G in 2020: Still just a private party

To hear the major mobile carriers talk about it, 5G is here. They’ve deployed it, it works, and it’s ready to start changing the world just about right away, with ultra-fast connectivity, low latency and a dramatically improved ability to handle huge numbers of different connections at once.Eventually, that will all be true – but, according to experts in the field, it isn’t yet, and most of it won’t take place within the coming calendar year. The 3GPP standards that will underpin all new-radio 5G technology are still not yet finalized, although that is expected to happen in early 2020, which means the much-touted 5G deployments in the U.S. are based partially on pre-standard technology.To read this article in full, please click here

Data centers in 2020: Automation, cheaper memory

It’s that time of year again when those of us in the press make our annual prognostications for the coming year. Some things we saw coming; the rise of the cloud and the advance of SSD. Others, like the return of many cloud migrations to on-premises or the roaring comeback of AMD, went right by us. We do our best but occasionally there are surprises.So with that, let’s take a peek into the always cloudy (no pun intended) crystal ball and make 10 data-center-oriented predictions.IoT spawns data-center growth in urban areas This isn’t a hard prediction to make since it’s already happening. For the longest time, data centers were placed in the middle of nowhere near renewable energy (usually hydro), but need is going to force more expansion in major metro areas. IoT will be one driver but so will the increasing use of data center providers like Equinix and DRT as interconnection providers.To read this article in full, please click here

What’s big in IT tech for the coming year

As the year winds down it's a good time to take a quick look ahead at what the new year might bring in order to be better prepared to make smart decisions.Nowhere is that more important than in IT, where the choices enterprise leaders make will have implications not only for themselves and their customers, but also for the overall economy, which depends more and more on corporate networks delivering business-critical services reliably.Here, we take a look how some of the most critical technologies will fare in 2020.What’s hot for Cisco in 2020 IDG Cisco is expected to continue its cloud, security, and SD-WANefforts in 2020, but there are hurdles to overcome. “Overall, I think it’s clear that Cisco needs to get into the cloud in a more effective way," said analyst Tom Nolle, president of CIMI Corp. "I think their recent reorg shows they understand that. Cloud Interconnect is a sideshow. What’s needed is infrastructure-independent development and deployment, which would relegate Cloud Interconnect to nothing but a network gateway.” (Read more.)To read this article in full, please click here

Counting down the days using bash

With some pretty important holidays right around the corner, you might need to be reminded how much longer you have to prepare.Fortunately, you can get a lot of help from the date command. In this post, we’ll look at ways that date and bash scripts can tell you how many days there are between today and some event that you’re anticipating.[Get regularly scheduled insights by signing up for Network World newsletters.] First a couple hints at how this is going to work. The date command’s %j option is going to show you today’s date as a number between 1 and 366. January 1st, as you’d expect, will be displayed as 1 and December 31st will be 365 or 366 depending on whether it’s leap year. Go ahead and try it. You should see something like this:To read this article in full, please click here

What’s hot for Cisco in 2020

As the industry gets ready to gear up for 2020 things have been a  little disquieting in networking land.That’s because some key players – Arista and Juniper in particular – have been reporting business slowdowns as new deals have been smaller than expected and cloud providers haven’t been as free-spending as in the past.[Get regularly scheduled insights by signing up for Network World newsletters.] Worldwide IT spending has been on the slow side, Gartner said in October that worldwide IT spending is projected to total $3.7 trillion in 2019, an increase of 0.4% from 2018, the lowest growth forecast so far in 2019. The good news: global IT spending is expected to rebound in 2020 with forecast growth of 3.7%, primarily due to enterprise software spending, Gartner stated.To read this article in full, please click here

Google Cloud bare-metal initiative targets migrating legacy apps from on-prem

In the cloud-services market, bare metal offerings have lagged behind virtualized ones, mostly because the use of the cloud for things like elastic apps and developer environments are better suited to instances with a native operating system.The term “bare metal” simply means no software of any kind, not even a hypervisor. Customers provide their own operating environments, and the provider offers nothing more than CPUs, memory, and storage. Up to now, IBM has led the charge with bare-metal services because SoftLayer, the major data-center provider it acquired in 2014, was heavily involved in that business.To read this article in full, please click here

Researchers experiment with glass-based storage that doesn’t require electronics cooling

Hard drives aren’t going to be capacious enough for future data archiving and retrieval requirements, scientists believe, as applications such as artificial intelligence, wide-scale Internet of Things connectivity, and virtual and augmented reality take hold. Glass could be the answer.Encoding in glass would have advantages over hard drives and other mediums, experts suggest. Holding capacity is greater, and the slivers of quartz being experimented with don’t need cooling or dehumidifying environments.Microsoft Research, working in the UK along with the University of Southampton, announced that it has been able to store an entire movie on a quartz, glass-based storage medium. The team stored and retrieved a full-length Superman film on a small slab of the special material that measures about 3 inches square and less than a tenth of an inch thick. .To read this article in full, please click here

Verizon, Amazon team to offer 5G edge cloud computing via AWS Wavelength

Amazon and Verizon will offer the ability to run AWS-based applications with ultra-low latency via the former’s new Wavelength edge service, the companies announced this week at AWS re:Invent, letting organizations realize the benefits of edge computing without having to roll their own edge devices.The idea is a pretty simple one: Place small data centers running AWS’ software next to Verizon’s 5G points of presence. What this means is that applications running in that 5G coverage area can send their data to those remote edge data centers for rapid processing, as opposed to traveling across Verizon’s network, to the Internet at large, to AWS, and all the way back down the chain.To read this article in full, please click here

AWS rolls out Outposts for on-premises hybrid cloud

Looking to further nudge the data-center crowd into the cloud world, Amazon Web Services announced the availability of its long-awaited Outposts hybrid-cloud service this week.Outposts delivers on-premises hardware and services that enables AWS cloud services inside enterprise data centers. That on-premises market is huge according to Amazon Web Services CEO Andy Jassy who told the AWS re:Invent 2019 conference audience 97% of the $3.7T IT market is still on-prem and that the industry is still at the very early stages of a shift from on premises to the cloud.To read this article in full, please click here
